Availability and Summary of Documents for Incorporation by Reference

    This document proposes to amend FAA Order 7400.11B, Airspace
Designations and Reporting Points, dated August 3, 2017, and effective
September 15, 2017. FAA Order 7400.11B is publicly available as listed
in the ADDRESSES section of this document. FAA Order 7400.11B lists
Class A, B, C, D, and E airspace areas, air traffic service routes, and
reporting points.

The Proposal

    The FAA is considering an amendment to Title 14, Code of Federal
Regulations (14 CFR) part 71 to amend Class E surface area airspace,
and Class E airspace extending upward from 700 feet or more above the
surface due to the decommissioning of the Altoona VOR and cancelation
of associated approaches at Altoona-Blair County Airport, Altoona, PA.
    The Class E surface area airspace would be amended to within a 4.7-
mile (from a 4-mile) radius of the airport, with a segment 1.0-mile
each side of the 026[deg] bearing from the airport to 8.7 miles
northeast. The segment extending from the Altoona VOR to 7.4 miles
northeast of the VOR would be removed.
    The Class E airspace area extending upward from 700 feet above the
surface would be amended to within an 11.2-mile (from a 6.5-mile)
radius of the airport. The segment extending from the Altoona VOR to 16
miles northeast of the VOR would be removed. These changes would
enhance the safety and management of IFR operations at the airport.
    Class E airspace designations are published in Paragraphs 6002 and
6005, respectively of FAA Order 7400.11B, dated August 3, 2017, and
effective September 15, 2017, which is incorporated by reference in 14
CFR 71.1. The Class E airspace designations listed in this document
will be published subsequently in the Order.

Regulatory Notices and Analyses

    The FAA has determined that this proposed regulation only involves
an established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
It, therefore: (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);
and (3) does not warrant preparation of a Regulatory Evaluation as the
anticipated impact is so minimal. Since this is a routine matter that
will only affect air traffic procedures and air navigation, it is
certified that this proposed rule, when promulgated, will not have a
significant economic impact on a substantial number of small entities
under the criteria of the Regulatory Flexibility Act.

Environmental Review

    This proposal will be subject to an environmental analysis in
accordance with FAA Order 1050.1F, ``Environmental Impacts: Policies
and Procedures'' prior to any FAA final regulatory action.

Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all
PIAGGIO AERO INDUSTRIES S.p.A Model P-180 airplanes. This AD results
from mandatory continuing airworthiness information (MCAI) issued by an
aviation authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as cracks at the joint between the hinge pin sub-assembly and
the lock pin of the main landing gear lever hinge fitting. We are
issuing this AD to require actions to address the unsafe condition on
these products.

DATES: This AD is effective October 18, 2013.
    The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 18,
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
The NPRM was published in the Federal Register on June 19, 2013 (78 FR
36691). The NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:

    During scheduled maintenance, cracks have been detected at the
joint between the hinge pin sub-assembly and the lock pin of the
main landing gear (MLG) lever hinge fitting (LHF) of a Piaggio P.180
aeroplane.
    The results of the subsequent investigation revealed that the
cracks were initiated by an unforeseen friction in the MLG wheel
lever sub-assembly.
    This condition, if not detected and corrected, could lead to a
structural failure of the MLG, possibly resulting in loss of control
of the aeroplane during take-off or landing runs.
    To address this potential unsafe condition, Piaggio Aero
Industries (PAI) issued Service Bulletin (SB) 80-0345 to provide
instructions for early identification of cracks in the MLG LHF and,
in case of identification of the crack, replacement of the MLG.
    For the reasons described above, this AD required inspections of
the MLG LHF and, depending on findings, replacement of the MLG.
    This AD is considered to be an interim action, and based on
gathered experience, further AD action may follow.

You may obtain further information by examining the MCAI in the AD
docket.

Comments

    We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the proposal
and the FAA's response to each comment.

Request To Change Compliance Time From Hours Time-in-Service (TIS) to
Landings

    Carlo Cardu of PIAGGIO AERO INDUSTRIES S.p.A requested the
compliance time be changed from hours TIS to landing, as recommended in
the related service bulletin, to take into account actual landing gear
usage.
    We partially agreed with the commenter to include landings as a
measure for the compliance of this AD because the unsafe condition
addressed in this AD is a function of cycles on the landing gear. We
disagreed with only using landings because this class of airplane does
not require landings to be recorded. If an operator does document
landings, this is an acceptable measure. However, if an operator does
not record landings, TIS is also an acceptable measure for compliance.
    We have changed the final rule AD action based on this comment.

Request To Change the Requirement To Replace the Main Landing Gear
(MLG) Lever Hinge Fitting (LHF)

    Carlo Cardu of PIAGGIO AERO INDUSTRIES S.p.A requested we change
the corrective action from replacing the MLG LHF with a

serviceable part to replacing the MLG with a serviceable part based on
the description of a serviceable part in the related service bulletin.
    The commenter also requested we change the language from MLG LHF to
MLG when referring to the inspections required after replacement of the
MLG.
    We agreed with the commenter. Based on the description of a
serviceable part in the service bulletin, the operator has options to
meet the intent of a serviceable part that do not increase the burden
on the owners/operators of the affected airplanes. We have changed the
final rule AD action based on this comment.

Request To Clarify Inspection Requirements for Newly Installed MLG

    Carlo Cardu of PIAGGIO AERO INDUSTRIES S.p.A requested changing all
repetitive inspection language for newly installed MLG. The commenter
suggested changing this AD to specify that a newly installed MLG is
subject to specific inspection reqirements.
    We agreed with the commenter and have changed the final rule AD
action based on this comment.

Request To Expand Criteria for Determining a ``Serviceable'' MLG

    Carlo Cardu of PIAGGIO AERO INDUSTRIES S.p.A requested additional
language be added to clarify the definition of a ``serviceable'' MLG.
    We agreed with the commenter and have changed the final rule AD
action based on this comment.

Conclusion

    We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD with the changes described previously. We have determined that
these minor changes:
     [Agr]re consistent with the intent that was proposed in
the NPRM (78 FR 36691, June 19, 2013) for correcting the unsafe
condition; and
     Do not add any additional burden upon the public than was
already proposed in the NPRM (78 FR 36691, June 19, 2013).

We also determined that these changes will not increase the economic
burden on any operator or increase the scope of this AD.

Interim Action

    We consider this AD interim action. We are requiring inspection(s)
of the left and right MLG LHF with a report to the manufacturer of the
results if cracks are found. We will work with the type certificate
holder to evaluate the report results to determine repetitive
inspection intervals and subsequent terminating action. Based on this
evaluation, we may initiate further rulemaking action to address the
unsafe condition identified in this AD.

Costs of Compliance

    We estimate that this AD will affect 109 products of U.S. registry.
We also estimate that it will take about 11 total work-hours, which is
2 work-hours for the initial visual inspection; 2 work-hours for the
detailed visual inspection; and 7 work-hours for the fluorescent
penetrant inspection, per product to comply with the basic requirements
of this AD. The average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of this AD on U.S.
operators to be $101,915, or $935 per product.
    In addition, we estimate that any necessary follow-on actions will
take about 7 work-hours and require parts costing $21,540 to replace a
left-hand LHF, for a cost of $22,153, and $20,662 to replace a right-
hand LHF, for a cost of $21,257.
    According to the manufacturer, some of the costs of this 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 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 above, I certify this AD:
    (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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone<PHONE_NUMBER>) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

2. The FAA amends Sec.  39.13 by adding the following new AD:

2013-18-04 PIAGGIO AERO INDUSTRIES S.p.A: Amendment 39-17577; Docket
No. FAA-2012-0962; Directorate Identifier 2012-CE-033-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective October 18,
2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model P-180
airplanes, all serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 32: Landing
Gear.

(e) Reason

    This AD was prompted by results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority
of another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as cracks
at the joint between the hinge pin sub-assembly and the lock pin of
the main landing gear (MLG) lever hinge fitting (LHF). We are
issuing this AD to prevent structural failure of the MLG LHF, which
could result in loss of control during take-off or landing runs.

(f) Actions and Compliance

    Unless already done, do the following actions in paragraphs
(f)(1) through (f)(8), including all subparagraphs, of this AD:
    (1) Within the next 200 landings after October 18, 2013 (the
effective date of this AD), or within the next 3 months after
October 18, 2013 (the effective date of this AD), whichever occurs
first, and before further flight after each MLG replacement,
visually inspect each MLG LHF for cracks and verify freedom of
rotation of the MLG wheel lever subassemblies. Do the inspection
following Part 1 of the Accomplishment Instructions in PIAGGIO AERO
INDUSTRIES S.p.A. Mandatory Service Bulletin No. 80-0345, dated
September 20, 2012; and Paragraph A of the Accomplishment
Instructions in Appendix A of PIAGGIO AERO INDUSTRIES S.p.A.
Mandatory Service Bulletin No. 80-0345, dated September 20, 2012,
which includes Messier-Dowty Service Bulletin No. P180-32-32, dated
September 10, 2012. The compliance times for the entire AD are
presented in landings; however, it is not mandatory to track
landings for this class of airplane. If an operator does not track
landings, 1 hour time-in-service (TIS) corresponds to 1 landing for
compliance with this AD.
    (2) If, during the inspection required in paragraph (f)(1) of
this AD, freedom of rotation of the MLG wheel lever subassembly is
not assured, before further flight, mark the LHF on the affected MLG
as ``inspect as per SB-80-0345'' with an indelible pen, and replace
the MLG with a serviceable part as defined in paragraph (f)(7) of
this AD. Do the replacement following Part 1 of the Accomplishment
Instructions in PIAGGIO AERO INDUSTRIES S.p.A. Mandatory Service
Bulletin No. 80-0345, dated September 20, 2012. The newly installed
MLG is subject to the inspection requirement specified in paragraph
(f)(1) of this AD and all repetitive inspection requirements
specified in paragraphs (f)(3) and (f)(4) of this AD.
    (3) Within the compliance times specified in paragraphs
(f)(3)(i), (f)(3)(ii), and (f)(3)(iii) of this AD, and repetitively
thereafter at intervals not to exceed 200 landings, do a detailed
visual inspection of each MLG LHF for cracks. Do the inspection
following Part 2 of the Accomplishment Instructions in PIAGGIO AERO
INDUSTRIES S.p.A. Mandatory Service Bulletin No. 80-0345, dated
September 20, 2012; and Paragraph B of the Accomplishment
Instructions in Appendix A of PIAGGIO AERO INDUSTRIES S.p.A.
Mandatory Service Bulletin No. 80-0345, dated September 20, 2012,
which includes Messier-Dowty Service Bulletin No. P180-32-32, dated
September 10, 2012.
    (i) As of October 18, 2013 (the effective date of this AD), if
the MLG LHF has accumulated 2,300 landings or less since new,
inspect before exceeding 2,500 landings since new.
    (ii) As of October 18, 2013 (the effective date of this AD), if
the MLG LHF has accumulated more than 2,300 landings since new, but
less than 2,500 landings since new, inspect within the next 200
landings after October 18, 2013 (the effective date of this AD).
    (iii) As of October 18, 2013 (the effective date of this AD), if
the MLG LHF has accumulated 2,500 landings or more since new,
inspect within the next 200 landings after October 18, 2013 (the
effective date of this AD), or within the next 3 months after
October 18, 2013 (the effective date of this AD), whichever occurs
first.
    (4) Within the compliance times specified in paragraphs
(f)(3)(i), (f)(3)(ii), and (f)(3)(iii) of this AD and repetitively
thereafter at intervals not to exceed 750 landings, do a fluorescent
penetrant inspection on each MLG LHF for cracks. Do the inspection
following Part 3 of the Accomplishment Instructions in PIAGGIO AERO
INDUSTRIES S.p.A. Mandatory Service Bulletin No. 80-0345, dated
September 20, 2012; and Paragraph C in Appendix A of PIAGGIO AERO
INDUSTRIES S.p.A. Mandatory Service Bulletin No. 80-0345, dated
September 20, 2012, which includes Messier-Dowty Service Bulletin
No. P180-32-32, dated September 10, 2012.
    (5) If, during any inspection required by paragraphs (f)(1),
(f)(3), (f)(4), (f)(7), and (f)(8) of this AD, including all
subparagraphs, any crack is found, before further flight, replace
the MLG with a serviceable part as defined in paragraph (f)(7) of
this AD. Do the replacement following the Accomplishment
Instructions in PIAGGIO AERO INDUSTRIES S.p.A. Mandatory Service
Bulletin No. 80-0345, dated September 20, 2012. The newly installed
MLG is subject to the inspection requirement specified in paragraph
(f)(1) of this AD and all repetitive inspection requirements
specified in paragraphs (f)(3) and (f)(4) of this AD.
    (6) Within 30 days after each MLG replacement, submit an
inspection result report to PIAGGIO AERO INDUSTRIES S.p.A at the
address specified in paragraph (h) of this AD using the Confirmation
Slip attached to PIAGGIO AERO INDUSTRIES S.p.A. Mandatory Service
Bulletin No. 80-0345, dated September 20, 2012.
    (7) For the purpose of this AD, a ``serviceable'' MLG is defined
as an airworthy MLG that has had the freedom of rotation verified
