Start Preamble

AGENCY:

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

ACTION:

Final rule.

SUMMARY:

We are adopting a new airworthiness directive (AD) for 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 the baggage door lockpins not engaging properly and the baggage door open light illuminating when the baggage door is not open, which could lead to the pilot disregarding a valid warning. We are issuing this AD to require actions to address the unsafe condition on these products.

DATES:

This AD is effective January 17, 2012.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the AD as of January 17, 2012.

ADDRESSES:

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 September 29, 2011 (76 FR 60396). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

One event of in-flight baggage door opening occurred on an in-service aeroplane due to a defective locking mechanism or installation thereof; the BAG DOOR warning light went on properly before the event, but was ignored by the pilot, who misinterpreted it as a false warning.

NOTE: false in-service BAG DOOR warnings had occurred on other P.180 aeroplanes, and Piaggio Aero Industries (PAI) had issued Service Bulletin (SB) No. 80-0223 revision 1 to improve the installation of the baggage door warning microswitch and to modify the locking mechanism if necessary.

This condition, if not detected and corrected, could lead to in-flight detachment of the door, which could hit and damage the left propeller and/or the vertical or horizontal stabilizer, possibly resulting in loss of control of the aeroplane, or in injuries to persons or damage to property on the ground.

This AD requires an inspection of the locking mechanism of the baggage door and its proper adjustment, in accordance with PAI SB No. 80-0289 revision 1; if baggage door lockpins do not reach the correct engagement, or false BAG DOOR warnings were reported by flight crew, this AD requires also a modification of the door mechanism in accordance with PAI SB No. 80-0223 revision 1.

Instances of the baggage door open light illuminating have occurred when the baggage door was not open. This condition, if not corrected, could result in the pilot disregarding a valid warning. 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 (76 FR 60396, September 29, 2011) 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 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 102 products of U.S. registry. We also estimate that it would take about 29 work-hours per product to comply with the basic requirements of this AD. The average labor rate is $85 per work-hour. Required parts would cost about $4,482 per product.

Based on these figures, we estimate the cost of the AD on U.S. operators to be 708,594, or $6,947 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 Start Printed Page 77370Executive 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 (76 FR 60396, September 29, 2011), 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.

Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

(3) Reporting Requirements: For any reporting requirement in this AD, a federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to a 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 Start Printed Page 77371valid OMB Control Number.
