AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for
Honeywell International Inc. TFE731-4, -4R, -5AR, -5BR, and -5R
turbofan engines. This proposed AD was prompted by a report of certain
interstage turbine transition (ITT) ducts failing to meet containment
capability requirements. This proposed AD would require replacing
certain ITT ducts. We are proposing this AD to prevent failure of the
ITT duct, which could lead to an uncontained part release, damage to
the engine, and damage to the airplane.

Discussion

    While the Honeywell Aerospace Olomouc facility in the Czech
Republic was reworking certain ITT ducts, forgings that were not
properly heat treated were installed on the affected engines. The heat
treatment is necessary for the ITT ducts, part number (P/N) 3075292-4,
to meet mechanical properties and the containment capability
requirements of the ITT duct design. ITT ducts with unacceptable
containment capability, if not corrected, could result in an
uncontained part release, damage to the engine, and damage to the
airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Honeywell Service Bulletin (SB) No. TFE731-72-3789,
dated March 23, 2015. The SB describes procedures for removing affected
ITT ducts. 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 of this
NPRM.

FAA's Determination

    We are proposing this NPRM because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.

Proposed AD Requirements

    This NPRM would require replacing certain ITT ducts, P/N 3075292-4.

Costs of Compliance

    We estimate that this proposed AD affects 47 engines installed on
airplanes of U.S. registry. We also estimate that it would take about 2
hours per engine to comply with this proposed AD. The average labor
rate is $85 per hour. We estimate that replacement parts would cost
$15,000 per engine. Based on these figures, we estimate the total cost
of the proposed AD to U.S. operators to be $712,990. Our cost estimate
is exclusive of possible warranty coverage.

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 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.

Airworthiness Directives; ATR--GIE Avions de Transport
R[eacute]gional Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 2009-18-
18, which applies to certain ATR--GIE Avions de Transport
R[eacute]gional Model ATR42 and ATR72 airplanes. AD 2009-18-18 requires
repetitive inspections for damage and absence of repair of the cockpit
forward side windows, and replacement if necessary. Since we issued
that AD, we received reports of a cockpit forward right-hand side blow
out during flight. This proposed AD would require repetitive detailed
inspections of the cockpit forward side window for damage and
discrepancies; replacement if necessary. Replacing both cockpit forward
side windows with approved windows would terminate the repetitive
detailed inspections. This proposed AD would also expand the
applicability of AD 2009-18-18. The actions required by AD 2009-18-18
are not required by this AD. We are proposing this AD to detect and
correct air/water leakage of the cockpit forward side window, which
could lead to rapid cabin decompression, resulting in loss of control
of the airplane.

DATES: We must receive comments on this proposed AD by January 13,
2014.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    On August 26, 2009, we issued AD 2009-18-18, Amendment 39-16014 (74
FR 46336, September 9, 2009). That AD required actions intended to
address an unsafe condition on certain ATR Model ATR42 and ATR72
airplanes.
    Since we issued AD 2009-18-18, Amendment 39-16014 (74 FR 46336,
September 9, 2009), we received reports of a cockpit forward right-hand
side blow out during flight. We also received reports of an air/water
leak, which is an indication that structural components within the
window have begun to deteriorate. The European Aviation Safety Agency
(EASA), which is the Technical Agent for the Member States of the
European Community, has issued EASA Airworthiness Directive 2013-0087,
dated April 9, 2013 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for the specified products. The MCAI states:

    In 2009, a Left-Hand (LH) forward side glass window of an ATR
72-212 aeroplane blew out while performing a ground pressure test.
The investigation results revealed some anomalies on the forward
side window at the level of the z-bar on the windows external side
and at the level of the inner retainer on the windows internal side.
Such anomalies are considered as precursors of this kind of failure.
Air or water leakages between the z-bar and the outer glass ply, or
between the inner retainer and inner glass ply indicate the presence
of deteriorating structural components in the window.
    Neither ATR nor PPG Aerospace have authorized repairs on the
window z-bar or z-bar sealant. Any attempted repairs on these
forward side window z-bars and/or z-bar sealants could lead to a
similar event as described above.
    In-flight loss of a forward side window would cause rapid cabin
decompression, possibly resulting in flight crew incapacitation and
consequent reduced control, or loss of control of the aeroplane, and
cause the risk of injury to persons on the ground. The loss of a
forward side window while the aeroplane is on the ground, due to

differential cabin pressure, could result in injury to aeroplane
occupants or to persons outside the aeroplane.
    To address this potential unsafe condition, EASA issued AD 2009-
0159-E [dated July 20, 2009] [(http://ad.easa.europa.eu/blob/easa_ad_2009_0159E_superseded.pdf/EAD_2009-0159-E_1)] [which
corresponds to FAA AD 2009-18-18, Amendment 39-116014 (74 FR 46336,
September 9, 2009)] to require repetitive inspections of the
affected LH and right-hand (RH) cockpit forward side glass windows
and, in case discrepancies are found as defined in PPG Aerospace
Service Bulletin (SB) NP-158862-001, the replacement of the
window(s).
    Since that [EASA] AD was issued, a cockpit forward RH-side
window blew out during flight on an ATR72-212 aeroplane. Degradation
of the window is considered to have been the cause for this failure.
    * * * [T]his [EASA] AD * * * requires to accomplish the
[detailed] inspections in accordance with the instructions of
Revision 1 of PPG Aerospace SB NP-158862-001, which provides more
information on examples of [damaged and] discrepant conditions.
    This [EASA] AD also requires the removal from service of the
affected Part Number (P/N) NP158862-1 and P/N NP158862-2 cockpit
forward side windows, which constitutes terminating action for the
repetitive inspections required by this AD.

    The corrective action is replacing windows, if damage and
discrepancies are found. Damage and discrepancies to detect during the
inspection include z-bar existing sealant repair, z-bar deformation,
separation or gap in the sealant bond between the retainer and inner
glass ply, z-bar deformation and retainer gap at same location, or z-
bar deformation and retainer gap in window corner.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating it in Docket No.
FAA-2013-0975.

Relevant Service Information

    PPG Aerospace has issued Service Bulletin NP-158862-001, Revision
1, dated January 10, 2013. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.

Differences Between This AD and the MCAI or Service Information

    Although EASA AD 2013-0087, dated April 9, 2013, specifies to
replace affected window(s) in accordance with the instructions of
ATR42/72 Job Instruction Card airplane maintenance manual (AMM) JIC 56-
12-00 RAI 10000, this proposed AD would require replacement of affected
window(s) using a method approved by the Manager, International Branch,
ANM-116, Transport Airplane Directorate, FAA; or the EASA (or its
delegated agent, or the Design Approval Holder with EASA design
organization approval).
    While paragraph (6) of EASA AD 2013-0087, dated April 9, 2013,
specifies to replace each PPG Aerospace P/N NP-158862-1 LH and P/N NP-
158862-2 RH cockpit forward side window with another approved cockpit
forward side window, this proposed AD would require that replacement
windows and procedures for their installation be approved by the
Manager, International Branch, ANM-116, Transport Airplane Directorate,
FAA; or the EASA (or its delegated agent, or the Design Approval Holder
with EASA design organization approval).

Costs of Compliance

    Based on the service information, we estimate that this proposed AD
would affect about 43 products of U.S. registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost on U.S.
             Action                   Labor cost        Parts cost     Cost per product          operators
----------------------------------------------------------------------------------------------------------------
Detailed Inspection............  1 work-hour x $85                $0  $85 per inspection  $3,655 per inspection
                                  per hour = $85 per                   cycle.              cycle.
                                  inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
this replacement.

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                Cost per
                Action                                 Labor cost                   Parts cost        product
----------------------------------------------------------------------------------------------------------------
Replacement...........................  4 work-hours x $85 per hour = $340......         $18,546         $18,886
----------------------------------------------------------------------------------------------------------------

    Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these costs. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not
required to respond to, nor shall a person be subject to penalty for
failure to comply with a collection of information subject to the
requirements of the Paperwork Reduction Act unless that collection of
information displays a current valid OMB control number. The control
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in
the Costs of Compliance section of this document and includes time for
reviewing instructions, as well as completing and

reviewing the collection of information. Therefore, all reporting
associated with this AD is mandatory. Comments concerning the accuracy
of this burden and suggestions for reducing the burden should be
directed to the FAA at 800 Independence Ave., SW., Washington, DC
20591. ATTN: Information Collection Clearance Officer, AES-200.

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 proposed 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.
    We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.

2009-18-18, Amendment 39-16014 (74 FR 46336, September 9, 2009), and
adding the following new AD:

ATR--GIE Avions de Transport R[eacute]gional: Docket No. FAA-2013-
0975; Directorate Identifier 2013-NM-082-AD.

(a) Comments Due Date

    We must receive comments by January 13, 2014.

(b) Affected ADs

    This AD supersedes AD 2009-18-18, Amendment 39-16014 (74 FR
46336, September 9, 2009).

(c) Applicability

    This AD applies to all ATR--GIE Avions de Transport
R[eacute]gional Model ATR42-200, -300, -320, and -500 airplanes; and
Model ATR72-101, -201, -102, -202, -211, -212, and -212A airplanes;
certificated in any category; all manufacturer serial numbers.

(d) Subject

    Air Transport Association (ATA) of America Code 56, Windows.

(e) Reason

    This AD was prompted by reports of a cockpit forward right-hand
side blow out during flight. We are issuing this AD to detect and
correct air/water leakage of the cockpit forward side window, which
could lead to rapid cabin decompression, resulting in loss of
control of the airplane.

(f) Compliance

    You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.

(g) Inspections

    For airplanes that are equipped with any PPG Aerospace cockpit
forward side glass window having part number (P/N) NP158862-1 or P/N
NP158862-2: At the applicable time specified in paragraph (g)(1) or
(g)(2) of this AD, do a detailed inspection of the cockpit forward
side window to detect any damage and discrepancies (z-bar existing
sealant repair, z-bar deformation, separation or gap in the sealant
bond between the retainer and inner glass ply, z-bar deformation and
retainer gap at same location, or z-bar deformation and retainer gap
in window corner), in accordance with the Accomplishment
Instructions of PPG Aerospace Service Bulletin NP-158862-001
Revision 1, dated January 10, 2013. Repeat the inspection thereafter
at intervals not to exceed 550 flight hours or 750 flight cycles,
whichever occurs first, except as required by paragraph (h) of this
AD.
    (1) For windows for which the total flight cycles can be
established, inspect within 2,000 flight cycles since first
installation of the cockpit forward side window, or within 10 days
after the effective date of this AD, whichever occurs later.
    (2) For windows for which the total flight cycles cannot be
established, inspect before the accumulation of 2,000 total flight
cycles on the airplane, or within 10 days after the effective date
of this AD, whichever occurs later.

(h) Conditions for Reduced Interval

    If any of the conditions specified in paragraphs (h)(1), (h)(2),
and (h)(3) of this AD is found during any inspection required by
paragraph (g) of this AD, reduce the interval of each subsequent
inspection as required by paragraph (g) of this AD to 50 flight
cycles or 7 days, whichever occurs later.
    (1) Sealant separation between the Z-bar and the outer glass
ply, with depth less than 4 millimeter (mm) (0.160 inches (in)).
    (2) Sealant separation between the inboard retainer and inner
glass ply, with depth less than 7.5 mm (0.300 in) and cumulative
length less than 300 mm (12.000 in).
    (3) Window showing both sealant separation between the Z-bar and
the outer ply, and separation between inboard retainer and inner
glass ply, common to the same hole location with a length less than
225 mm (8.860 in), and not covering the entire arc of a window
corner.
