AD 2007-13-18

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:

The aim of the Airworthiness Directive (AD) is to introduce a new life limit for engine and Nose Landing Gear (NLG) mounts installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as defined in the updated Airworthiness Limitations Section (ALS) of the relevant Aircraft Maintenance Manuals (AMM).

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

Final rule.

2007-13-18 SOCATA--Groupe Aerospatiale: Amendment 39-15122; Docket No. FAA-2007-27432; Directorate Identifier 2007-CE-017-AD.

Effective Date

(a) This airworthiness directive (AD) becomes effective August 10, 2007.

Affected ADs

(b) None.

Applicability

(c) This AD applies to Models TB 9, TB 10, and TB 200 airplanes, all serial numbers, certificated in any category.

Subject

(d) Air Transport Association of America (ATA) Code 5: Time Limits.

Reason

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

The aim of this Airworthiness Directive (AD) is to introduce a new life limit for engine and Nose Landing Gear (NLG) mounts installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as defined in the updated Airworthiness Limitations Section (ALS) of the relevant Aircraft Maintenance Manuals (AMM).

This AD requires introduction of the new 10,000 Flight Hour life limit for engine and NLG mounts into the operator's maintenance program through the Revision 18 of the AMM.

Actions and Compliance

(f) Unless already done, within the next 30 days after August 10, 2007 (the effective date of this AD), incorporate the life limits in the Airworthiness Limitations documents presented in paragraphs (f)(1), (f)(2), and (f)(3) of this AD into the FAA- approved maintenance program, as applicable. This may be done by updating the Airworthiness Limitations Section of the airplane maintenance manual (AMM) and inserting the following applicable revision. The owner/operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7) may do this action. Make an entry in the aircraft records showing compliance with this portion of the AD following section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).

(1) For Model TB 9 airplanes: Use SOCATA TB 9 Model Maintenance Manual, 04, Airworthiness Limitations, Revision 18, dated September 2006,or later revision that incorporates the same life limit for the engine mount and NLG mount as the above referenced Revision 18;

(2) For Model TB 10 airplanes: Use SOCATA TB 10 Model Maintenance Manual, 04, Airworthiness Limitations, Revision 18, dated September 2006, or later revision that incorporates the same life limit for the engine mount and NLG mount as the above referenced Revision 18; or

(3) For Model TB 200 airplanes: Use SOCATA TB 200 Model Maintenance Manual, 04, Airworthiness Limitations, Revision 18, dated September 2006, or later revision that incorporates the same life limit for the engine mount and NLG mount as the above referenced Revision 18.

FAA AD Differences

Note: This AD differs from the MCAI and/or service information as follows: No Differences.

Other FAA AD Provisions

(g) The following provisions also apply to this AD:

(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, has the authority to approveAMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Albert J.

Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. 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, under the provisions of the Paperwork Reduction Act(44 U.S.C. 3501 et seq.), the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.

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 April 24, 2007 (72 FR 20300). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states that:

The aim of this Airworthiness Directive (AD) is to introduce a new life limit for engine and Nose Landing Gear (NLG) mounts installed on EADS SOCATA TB 9, TB 10 and TB 200 airplanes, as defined in the updated Airworthiness Limitations Section (ALS) of the relevant Aircraft Maintenance Manuals (AMM).
This AD requires introduction of the new 10,000 Flight Hour life limit for engine and NLG mounts into the operator's maintenance program through the Revision 18 of the AMM.

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 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 146 products of U.S. registry. We also estimate that it will take about 0.5 work-hours per product to comply with basic requirements of this AD. The average labor rate is $80 per work-hour.

Based on these figures, we estimate the cost of this AD to the U.S. operators to be $5,840 or $40 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 developon 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://dms.dot.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.
