Airworthiness Directives; SOCATA Model TBM 700 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the products listed above. This proposed AD 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:
It has been discovered that the foam inside the towing bar box is not conformed to the certification specification, and especially the flame resistance properties.
In case of fire, in the front baggage compartment, the non conformed foam could rapidly propagate the flames and/or emit toxic fumes in the cabin.
The proposed AD would require actions that are intended to address the unsafe condition described in the MCAI.
DATES: We must receive comments on this proposed AD by February 18, 2010.
ADDRESSES: You may send comments by any of the following methods:
Federal eRulemaking Portal: Go to http:// www.regulations.gov. Follow the instructions for submitting comments.
Fax: (202) 493-2251.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
AD No.: 2009-0238-E, dated October 30, 2009 (referred to after this as
``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states:
It has been discovered that the foam inside the towing bar box is not conformed to the certification specification, and especially the flame resistance properties.
In case of fire, in the front baggage compartment, the non conformed foam could rapidly propagate the flames and/or emit toxic fumes in the cabin.
For the reason stated above the Airworthiness Directive (AD), as a temporary measure, mandates the removal of the foam, pending a foam change.
You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
SOCATA has issued Mandatory Service Bulletin SB 70-179, dated
October 2009. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they have notified us of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all information and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.
Differences Between This Proposed 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
Page 90
substantively from the information provided in the MCAI and related service information.
We might also have proposed 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 proposed AD.
Costs of Compliance
We estimate that this proposed AD will affect 164 products of U.S. registry. We also estimate that it would take about 0.5 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $80 per work-hour.
Based on these figures, we estimate the cost of the proposed AD on
U.S. operators to be $6,560, 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 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); 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 proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES 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] 2. The FAA amends Sec. 39.13 by adding the following new AD:
SOCATA: Docket No. FAA-2009-1256; Directorate Identifier 2009-CE- 064-AD.
Comments Due Date
(a) We must receive comments by February 18, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to model TBM 700 airplanes, serial numbers
(S/N) 331 through 9999, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 9: Towing and Taxing.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:
It has been discovered that the foam inside the towing bar box is not conformed to the certification specification, and especially the flame resistance properties.
In case of fire, in the front baggage compartment, the non conformed foam could rapidly propagate the flames and/or emit toxic fumes in the cabin.
For the reason stated above the Airworthiness Directive (AD), as a temporary measure, mandates the removal of the foam, pending a foam change.
Actions and Compliance
(f) Unless already done, within the next 20 hours time-in- service after the effective date of this AD or within the next 30 days after the effective date of this AD, whichever occurs first, remove the foam from the towing bar stowage box following SOCATA
Mandatory Service Bulletin SB 70-179, dated October 2009.
Note 1: Airplanes delivered after October 13, 2009, may have had
SOCATA SB 70-179, dated October 2009, incorporated at the factory
(S/N 510 and S/N 529 through 9999).
FAA AD Differences
Note 2: 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 Office, FAA, has the authority to approve AMOCs for this
AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Albert Mercado, Aerospace Engineer, FAA, Small
Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4119; fax: (816) 329-4090. 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.
