14 CFR Part 39

[Docket No. FAA-2010-0734 Directorate Identifier 2010-CE-036-AD; 
Amendment 39-16474; AD 2010-21-14]

Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A Model 
PIAGGIO P-180 Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. 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:

    Due to a manufacturing error, some rivets, required by drawings, 
were not installed in the joints between two ceiling beams and the 
rear pressurized bulkhead.
    If left uncorrected, long term fatigue stress could locally 
weaken the structure, compromising the fuselage structural 
integrity.

We are issuing this AD to require actions to correct the unsafe 
condition on these products.

DATES: This AD becomes effective November 18, 2010.
    On November 18, 2010, the Director of the Federal Register approved 
the incorporation by reference of certain publications listed in this 
AD.

ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at Document Management Facility, U.S. 
Department of Transportation, Docket Operations, M-30, West Building 
Ground Floor, Room W12-140, 1200 New Jersey Avenue, SE., Washington, DC 
20590.

Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas 
City, Missouri 64106; telephone: (816) 329-4145; fax: (816) 329-4090.

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. 
That NPRM was published in the Federal Register on July 23, 2010 (75 FR 
43105). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    Due to a manufacturing error, some rivets, required by drawings, 
were not installed in the joints between two ceiling beams and the 
rear pressurized bulkhead.
    If left uncorrected, long term fatigue stress could locally 
weaken the structure, compromising the fuselage structural 
integrity.
    This AD requires the accomplishment of Piaggio Aero Industries 
(PAI) Service Bulletin (SB) 80-0268 original issue, which contains 
instructions to rework the affected area, thus restoring the 
fuselage design strength as well as the fatigue specifications of 
the structure.

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. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information

[[Page 63059]]

provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow FAA policies. Any such differences are 
highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 6 products of U.S. registry. 
We also estimate that it will take about 30 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts will cost about $100 per product.
    Based on these figures, we estimate the cost of this AD to the U.S. 
operators to be $15,900 or $2,650 per product.

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 DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and
    (3) 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 AD and placed it in the AD Docket.

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 (800) 647-5527) is in the ADDRESSES 
section. Comments will be available in the AD docket shortly after 
receipt.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 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 AD:

2010-21-14 PIAGGIO AERO INDUSTRIES S.p.A: Amendment 39-16474; Docket 
No. FAA-2010-0734; Directorate Identifier 2010-CE-036-AD.

Effective Date

    (a) This airworthiness directive (AD) becomes effective November 
18, 2010.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to PIAGGIO AERO INDUSTRIES S.p.A Model 
PIAGGIO P-180 airplanes, serial numbers 1166 through 1175, 
certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 53: 
Fuselage.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    Due to a manufacturing error, some rivets, required by drawings, 
were not installed in the joints between two ceiling beams and the 
rear pressurized bulkhead.
    If left uncorrected, long term fatigue stress could locally 
weaken the structure, compromising the fuselage structural 
integrity.
    This AD requires the accomplishment of Piaggio Aero Industries 
(PAI) Service Bulletin (SB) 80-0268 original issue, which contains 
instructions to rework the affected area, thus restoring the 
fuselage design strength as well as the fatigue specifications of 
the structure.

Actions and Compliance

    (f) Unless already done, within 200 hours time-in-service (TIS) 
after November 18, 2010 (the effective date of this AD), replace the 
rivets of the joint brackets on the right-hand and left-hand beam 
with ``Hi-Lok'' fasteners, following the accomplishment instructions 
of PIAGGIO AERO INDUSTRIES S.p.A. Service Bulletin (Mandatory) N.: 
80-0268, REV. 0, dated December 18, 2008.
