RIN 2120-AA64

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of
comment period.

-----------------------------------------------------------------------

SUMMARY: We are revising an earlier proposed airworthiness directive
(AD) for certain The Boeing Company Model 767-200, -300, and -400ER
series airplanes. The NPRM proposed an inspection for plastic
couplings, corrective actions if necessary, and installation of new
spray shrouds. The NPRM was prompted by a report of the engine
indication and crew alerting system (EICAS) display system
malfunctioning during flight. This action revises the NPRM by adding,
for certain airplanes, a general visual inspection of the spray shield
and related investigative and corrective actions if necessary. We are
proposing this supplemental NPRM (SNPRM) to prevent an uncontrolled
water leak from a defective potable water system coupling, which could
cause the main equipment center (MEC) line replaceable units (LRUs) to
become wet, resulting in an electrical short and potential loss of
several functions essential for safe flight. Since these actions impose
an additional burden over that proposed in the NPRM, we are reopening
the comment period to allow the public the chance to comment on these
proposed changes.

DATES: We must receive comments on this SNPRM by May 31, 2016.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that
would apply to certain The Boeing Company Model 767-200, -300, and -
400ER series airplanes. The NPRM published in the Federal Register on
August 14, 2014 (79 FR 47597) (``the NPRM''). The NPRM proposed to
require an inspection for plastic couplings, corrective actions if
necessary, and installation of new spray shrouds.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM, Boeing has issued Boeing Alert Service
Bulletin 767-38A0073, Revision 2, dated August 10, 2015. Boeing Alert
Service Bulletin 767-38A0073, Revision 2, dated August 10, 2015, adds,
for certain airplanes, a general visual inspection of the spray shield
to determine if it has two slits and is installed correctly, and
related investigative and corrective actions if

necessary. We added a new paragraph (h) to require this inspection and,
if necessary, related investigative and corrective actions as
applicable. We redesignated subsequent paragraphs accordingly.

Comments

    We gave the public the opportunity to comment on the NPRM. The
following presents the comments received on the NPRM and the FAA's
response to each comment.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing (APB) stated that the installation of
winglets per supplemental type certificate ST01920SE (http://
rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect
the accomplishment of the manufacturer's service instructions. APB also
expressed that it would provide supporting data to the FAA upon
request.
    We agree with the commenter that STC ST01920SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect
the accomplishment of the manufacturer's service instructions.
Therefore, the installation of STC ST01920SE does not affect the
ability to accomplish the actions required by this proposed AD. We have
not changed this proposed AD in this regard.

Request To Include Latest Service Information

    Boeing requested that we revise the NPRM to refer to Boeing Service
Bulletin 767-38A0073, Revision 1, dated November 5, 2014, and to note
that no more work is necessary on any airplanes on which the actions
specified in Boeing Alert Service Bulletin 767-38A0073, dated November
12, 2013, have been done (the NPRM referred to Boeing Alert Service
Bulletin 767-38A0073, dated November 12, 2013, as the appropriate
source of service information). Boeing also stated that the revision
includes some minor changes in the Work Instructions and corrects some
part numbers in the Material Information section. Boeing noted that the
revised service information includes the statement ``no more work is
necessary on any airplane(s) changed in accordance with the original
issue of the service bulletin.''
    We agree to include the latest revision of the service information
in this proposed AD. As stated previously, Boeing Alert Service
Bulletin 767-38A0073, Revision 2, dated August 10, 2015, has been
issued. This proposed AD would require that all actions be completed
using Boeing Alert Service Bulletin 767-38A0073, Revision 2, dated
August 10, 2015. We have also added a new paragraph (k) to this
proposed AD to give credit for actions done before a certain date using
Boeing Alert Service Bulletin 767- 38A0073, dated November 12, 2013,
and Boeing Service Bulletin 767-38A0073, Revision 1, dated November 5,
2014. We have redesignated subsequent paragraphs accordingly.

Request To Revise the Inspection and Installation Paragraph (Paragraph
(g) of the NPRM)

    Boeing requested that we revise the ``Inspection and Installation''
paragraph (paragraph (g) of the proposed AD (in the NPRM)) to delete
the following sentence:

    Do all applicable corrective actions within the compliance time
identified in paragraph 1.E., ``Compliance,'' of Boeing Alert
Service Bulletin 767-38A0073, dated November 12, 2013, except as
required by paragraph (h) of this AD.''

Boeing claimed that the sentence is repetitive and that it adds no new
information beyond what is captured in the first two sentences of
paragraph (g) of the proposed AD (in the NPRM).
    We do not agree to revise this proposed AD to delete the sentence
as requested because the sentence is necessary to indicate the
compliance time for the corrective actions. We have made no changes to
this proposed AD in this regard.

Request To Revise Costs of Compliance Section by Adding Leak Test Costs

    Boeing requested that we revise the Costs of Compliance section of
the NPRM to account for the hours to perform the leak test on each
airplane. Boeing explained that Boeing Alert Service Bulletin 767-
38A0073, dated November 12, 2013, contains estimates of 3 work-hours
for the leak test. Boeing reasoned that the hours to perform the leak
test following any coupling replacement were not included in the cost
estimate.
    We agree to revise the Costs of Compliance section of this SNPRM to
add the costs to perform a leak test, for the reason indicated by
Boeing. We have included this cost in the ``Related investigative
actions'' row of the on-condition costs.

Request To Revise Parts Installation Prohibition Paragraph

    United Airlines (UA) requested that we revise the ``Parts
Installation Prohibition'' paragraph (paragraph (i) of the proposed AD
(in the NPRM)) to refer to part number (P/N) ``CA620 series'' or P/N
``CA625 series,'' instead of simply ``P/N CA620'' or ``P/N CA625.'' UA
explained that calling out P/N CA620 or P/N CA625 comprises only a
portion of the part number.
    We agree to revise the ``Parts Installation Prohibition'' paragraph
(paragraph (j) of this proposed AD, which was referred to as paragraph
(i) of the proposed AD (in the NPRM)) to specify P/N ``CA620 series''
or P/N ``CA625 series,'' for the reason explained by UA. A complete
part number is formatted to provide information; e.g., for ``CA620XX-
YYZZ,'' XX identifies the size, YY identifies the material, and ZZ is a
color code; this proposed AD would prohibit P/N CA620 and P/N CA625
regardless of size, material, and color.

Request To Allow Use of Airplane Maintenance Manual (AMM)

    UA explained that Boeing Alert Service Bulletin 767-38A0073, dated
November 12, 2013, refers to Subject 38-10-00, Potable Water System, of
Chapter 38, Water/Waste, of the Boeing 767 AMM as an accepted procedure
to do a potable water system leak test on any replaced coupling and
repair any leak. UA stated that the leak test on ``any replaced
coupling'' in the potable water supply lines is only a portion of the
referenced procedure, yet Subject 38-10-00, Potable Water System, of
Chapter 38, Water/Waste, of the Boeing 767 AMM encompasses the water
system as a whole. Steps (a) through (c) of paragraph G.9 in AMM 38-10-
10 apply to the fill, drain, and overflow port, whereas step (d)
applies to the water lines that supply lavatory and galley water. UA
interpreted this requirement as referencing the steps in the Subject
38-10-00, Potable Water System, of Chapter 38, Water/Waste, of the
Boeing 767 AMM that apply to any replaced coupling for compliance
purposes.
    We agree to clarify. Only the steps in the AMM for a leak test that
apply to any replaced coupling must be done for compliance purposes. We
have made no changes to this proposed AD in this regard.

Request To Include an Alternative Leak Test or Protection

    UA requested that we revise paragraph (g) of the proposed AD (in
the NPRM) to add an alternative leak test, or protection of the
electronics during the leak test. UA stated that Boeing Alert Service
Bulletin 767-38A0073, dated November 12, 2013, specifies a

potable water supply line leak test in the electronic/equipment (EE)
bay after repairs, which may produce leaks into the EE. UA advised
providing protection from water spray in the event of a leak, since the
shrouds may not have been installed at this point. When a sleeve is
installed over the O-rings, sometimes the sleeve tends to ``walk'' or
jam unevenly over the O-rings, causing an unexpected leak.
    We disagree with the commenters request to add an alternative leak
test, or to require protection of the electronics during the leak test.
However, we agree that operators can take optional protective measures
to cover or shield their equipment against water spray during the leak
test. We have added note 1 to paragraph (g) of this proposed AD for
clarification. We have determined that an alternative leak test is not
necessary, and no requirement for electronics protection is needed. If
present after the couplings have been swapped, the leak should be
detected soon after the leak test is initiated, so the potential amount
of water leaked would be minimal. If the sleeve was not properly
installed, it should be obvious because the coupling could not be fully
closed without the secondary retention strap secured. If damage to the
O-ring occurred when the sleeve was installed, the leakage would be
minimal. The electronics are contained inside panels and racks, and
minimal water leakage should not be a problem. Only an undetected leak
for extended duration, or major leaks spraying water all over, would be
problematic since the racks/panels are not waterproof.

FAA's Determination

    We are proposing this SNPRM because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of these same type
designs. Certain changes described above expand the scope of the NPRM.
As a result, we have determined that it is necessary to reopen the
comment period to provide additional opportunity for the public to
comment on this SNPRM.

Proposed Requirements of This SNPRM

    This SNPRM would require accomplishing the actions specified in the
service information described previously. For information on the
procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0571.
    The phrase ``related investigative actions'' is used in this
proposed AD. ``Related investigative actions'' are follow-on actions
that (1) are related to the primary action, and (2) further investigate
the nature of any condition found. Related investigative actions in an
AD could include, for example, inspections.
    The phrase ``corrective actions'' is used in this proposed AD.
``Corrective actions'' are actions that correct or address any
condition found. Corrective actions in an AD could include, for
example, repairs.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 767-38A0073, Revision 2,
dated August 10, 2015. The service information describes procedures for
a general visual inspection for plastic potable water couplings and
applicable related investigative and corrective actions; installation
of new spray shrouds; and a general visual inspection of the spray
shield to determine if it has two slits, and is installed correctly,
and applicable related investigative and corrective actions. This
service information is reasonably available because the interested
parties have access to it through their normal course of business or by
the means identified in the ADDRESSES section.

Costs of Compliance

    We estimate that this proposed AD affects 136 airplanes of U.S.
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
             Action                  Labor cost        Parts cost     Cost per product    Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Part 1--General visual           Up to 3 work-hours              $0  Up to $255........  Up to $34,680.
 inspection (Groups 1 through     x $85 per hour =
 3, 9, and 11, Configuration 1;   $255.
 Groups 4-8, 10, and 12-13)
 (136 airplanes).
Part 2--General visual           2 work-hours x $85               0  $170..............  $5,440.
 inspection (Group 9,             per hour = $170.
 Configuration 1, and Group 10)
 (32 airplanes).
Part 3--Install spray shrouds..  3 work-hours x $85             330  $585..............  $79,560.
                                  per hour = $255.
Part 4--General visual           2 work-hours x $85               0  $170..............  $5,100.
 inspection (Groups 1 through     per hour = $170.
 3, 9, and 11, Configuration 2)
 (30 airplanes).
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition
actions that would be required based on the results of the inspection.
We have no way of determining the number of aircraft that might need
these actions:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                 Action                          Labor cost            Parts cost         Cost per  product
----------------------------------------------------------------------------------------------------------------
Related investigative actions..........  3 work-hours x $85 per                  $0  $255.
                                          hour = $255.
Corrective actions.....................  Up to 1 work-hour x $85                 53  Up to $138.
                                          per hour = $85.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed
AD may be covered under warranty, thereby reducing the cost impact on
affected individuals. We do not control warranty coverage for affected
individuals. As a result, we have included all costs in our cost
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation Programs''
describes in more detail the scope of the Agency's authority.
    We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701: ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect on the States, on the relationship
between the national Government and the States, or on the distribution
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed
regulation:
    (1) Is not a ``significant regulatory action'' under Executive
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness
directive (AD):

The Boeing Company: Docket No. FAA-2014-0571; Directorate Identifier
2014-NM-059-AD.

(a) Comments Due Date

    We must receive comments by May 31, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 767-200, -300, and -

specified in paragraph (g) of this AD, if those actions were
performed before the effective date of this AD using Boeing Alert
Service Bulletin 767-38A0073, dated November 12, 2013; or Boeing
Service Bulletin 767-38A0073, Revision 1, dated November 5, 2014;
which are not incorporated by reference in this AD.

(l) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO),
FAA, has the authority to approve AMOCs for this AD, if requested
using the procedures found in 14 CFR 39.19. In accordance with 14
CFR 39.19, send your request to your principal inspector or local
Flight Standards District Office, as appropriate. If sending
information directly to the manager of the ACO, send it to the
attention of the person identified in paragraph (m)(1) of this AD.
Information may be emailed to<EMAIL_ADDRESS>    (2) Before using any approved AMOC, notify your appropriate
principal inspector, or lacking a principal inspector, the manager
of the local flight standards district office/certificate holding
district office.
    (3) An AMOC that provides an acceptable level of safety may be
used for any repair,

modification, or alteration required by this AD if it is approved by
the Boeing Commercial Airplanes Organization Designation
Authorization (ODA) that has been authorized by the Manager, Seattle
ACO, to make those findings. To be approved, the repair method,
modification deviation, or alteration deviation must meet the
certification basis of the airplane, and the approval must
specifically refer to this AD.
    (4) For service information that contains steps that are labeled
as Required for Compliance (RC), the provisions of paragraphs
(l)(4)(i) and (l)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step
and any figures identified in an RC step, must be done to comply
with the AD. An AMOC is required for any deviations to RC steps,
including substeps and identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted
methods in accordance with the operator's maintenance or inspection
program without obtaining approval of an AMOC, provided the RC
steps, including substeps and identified figures, can still be done

Airworthiness Directives; Agusta S.p.A. (Agusta) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

-----------------------------------------------------------------------

SUMMARY: We are superseding airworthiness directive (AD) 2014-02-08 for
Agusta Model A109C, A109S, A109K2, A109E, and AW109SP helicopters. AD
2014-02-08 required inspecting the lock wires securing the tail rotor
(T/R) duplex bearing locking nut (locking nut) to determine whether any
lock wires are missing or damaged. This AD retains some of the
requirements of AD 2014-02-08 but removes the terminating action,
expands the applicability, and adds a daily pilot check. This AD was
prompted by reports of loosening T/R locking nuts. These actions are
intended to prevent failure of the T/R and subsequent loss of control
of the helicopter.

Discussion

    On January 16, 2014, we issued AD 2014-02-08, Amendment 39-17736
(79 FR 5257, January 31, 2014) for Agusta Model A109C, A109S, and
A109K2 helicopters, and certain serial-numbered Model A109E and AW109SP
helicopters. AD 2014-02-08 required repetitively inspecting the lock
wires securing the T/R locking nut to determine whether any lock wires
are missing or damaged, installing a second lock wire if only one was
installed, and reassembling the housing and slider group of the T/R
rotating controls as terminating action for the inspections. AD 2014-
02-08 was prompted by reports of loosening T/R locking nuts. Those
actions are intended to prevent failure of the T/R and subsequent loss
of control of the helicopter.
    AD 2014-02-08 was prompted by AD No. 2012-0195-E, dated September
24, 2012, and corrected September 25, 2012, issued by EASA, the
Technical Agent for the Member States of the European Union, to correct
an unsafe condition for certain Agusta Model A109E, A109LUH, A109S,
AW109SP, A109C, and A109K2 helicopters. EASA advised of the T/R locking
nut loosening on Model A109 helicopters and that one or both of the
lock wires securing the locking nut were either damaged or absent from
the T/R. EASA states that this condition could lead to failure of the
T/R function and subsequent loss of control of the helicopter. AD No.
2012-0195-E requires repetitively inspecting the lock wires and
removing and reassembling the housing and slider group of the T/R
rotating controls, which is terminating action for the inspections.

Actions Since AD 2014-02-08 Was Issued

    Since we issued AD 2014-02-08 (79 FR 5257, January 31, 2014), a
failure of a T/R duplex bearing ring nut installation occurred after
the housing and slider group of the T/R rotating controls had been
reassembled. Therefore, we are superseding AD 2014-02-08 to remove the
reassembly as terminating action. Because of additional reports of the
loosening of the bearing locking nut and the increased risk of failure
of a lock wire, we are retaining the 25-hour TIS inspection. We are
also requiring a daily pilot check to enhance detection of a failure of
a T/R duplex bearing ring nut installation. AD 2014-02-18 did not apply
to certain serial-numbered helicopters because the terminating action
had already been performed on those models. Because we have determined
that the terminating action does not correct the unsafe condition, we
have expanded the applicability to include all serial-numbered
helicopters for the Model A109C, A109S, A109K2, A109E, and AW109SP.
EASA has not changed any of the requirements in its AD, and Agusta has
not revised its service information.
    We have also corrected the design holder's name from AgustaWestland
S.p.A. to Agusta S.p.A., as specified by the current FAA type
certificate.

FAA's Determination

    These helicopters have been approved by the aviation authority of
Italy and are approved for operation in the United States. Pursuant to
our bilateral agreement with Italy, EASA, its technical representative,
has notified us of the unsafe condition described in its AD. We are
issuing this AD because we evaluated all known information provided by
EASA and determined that an unsafe condition is likely to exist or
develop on other helicopters of these same type designs.

Related Service Information

    Agusta issued Bollettino Tecnico (BT) Nos. 109-134, 109EP-121,
109S-48, 109K-54, and 109SP-051, all dated September 21, 2012, for
Model A109C, A109E, A109S, A109K2, and AW109SP helicopters. These BTs
specify inspecting for the presence and condition of the two locking
wires. The BTs also specify if one lock wire is present and no damage
is reported, installing a second lock wire. The BTs specify if one or
both of the lock wires are damaged, removing and disassembling the
housing and slider group of the T/R controls.

AD Requirements

    This AD expands the applicability to include all serial-numbered
helicopters. This AD retains the initial and repetitive inspections
required by AD 2014-02-08 (79 FR 5257, January 31, 2014) and retains
the requirement to remove and reassemble the housing and slider group
of the T/R rotating controls if one or both lock wires are damaged.
This AD also requires a daily pilot check of each lock wire securing
the T/R locking nut. An owner/operator (pilot) may perform the required
visual check and must enter compliance with the applicable paragraph of
the AD into the helicopter maintenance record in accordance with 14 CFR
43.9(a)(1) through (4) and 14 CFR 91.417(1)(2)(v). A pilot may perform
this check because it involves only looking at the visible area of the
lock wire securing the T/R locking nut to the housing. This check is an
exception to our standard maintenance regulations.

Differences Between This AD and the EASA AD

    This AD requires a daily pilot check of the lock wire, while the
EASA does not. The EASA AD requires removing and reassembling the
housing and slider

group of the T/R rotating controls as terminating action, regardless of
whether the lock wire is damaged, and this AD does not. The EASA AD
applies to certain serial-numbered helicopters, and this AD applies to
all serial-numbered helicopters of each model.

Interim Action

    We consider this AD to be an interim action. If final action is
later identified, we might consider further rulemaking then.

Costs of Compliance

    We estimate that this AD affects 122 helicopters of U.S. Registry.
We estimate that operators may incur the following costs to comply with
this AD. The average labor rate is estimated to be $85 per work-hour.
Inspecting the lock wire takes about 0.25 work-hour, and the required
parts cost is negligible, for a cost per helicopter of $22 and a total
cost to U.S. operators of $2,684 per inspection cycle. Removing and
reassembling the housing and slider group of the T/R rotating controls
requires about 8 work-hours for a cost per helicopter of $680.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting
these AD requirements would delay implementing the safety actions
needed to correct this known unsafe condition. Therefore, we find that
the risk to the flying public justifies waiving notice and comment
prior to adopting this rule because the previously described unsafe
condition can adversely affect the controllability of the helicopter.
Since cases of loosening of the T/R duplex bearing locking nut continue
to occur, we are requiring a daily pilot check, which must be performed
within 24 hours.
    Since an unsafe condition exists that requires the immediate
adoption of this AD, we determined that notice and opportunity for
public comment before issuing this AD are impracticable and that good
cause exists for making this amendment effective in less than 30 days.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, section 106, describes the
authority of the FAA Administrator. ``Subtitle VII: Aviation
Programs,'' describes in more detail the scope of the Agency's
authority.
    We are issuing this rulemaking under the authority described in
``Subtitle VII, Part A, Subpart III, Section 44701: General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications
under Executive Order 13132. This AD will not have a substantial direct
effect on the States, on the relationship between the national
Government and the States, or on the distribution of power and
responsibilities among the various levels of government.
    For the reasons discussed, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order
12866;
    2. Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska to the extent that
it justifies making a regulatory distinction; and
    4. Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
    We prepared an economic evaluation of the estimated costs to comply
with this AD and placed it in the AD docket.
