Airworthiness Directives; EADS 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) 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 a report of a master cylinder yoke failure. 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 December 28, 2006.
ADDRESSES: You may send comments by any of the following methods:

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
The FAA is implementing a new process for streamlining the issuance of ADs related to MCAI. The streamlined process will allow us to adopt MCAI safety requirements in a more efficient manner and will reduce safety risks to the public. This process continues to follow all FAA AD issuance processes to meet legal, economic, Administrative Procedure Act, and Federal Register requirements. We also continue to meet our technical decision-making responsibilities to identify and correct unsafe conditions on U.S.-certificated products.
This proposed AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The proposed AD contains text copied from the MCAI and for this reason might not follow our plain language principles.
Comments Invited
We invite you to send any written relevant data, views, or arguments about this proposed AD. Send your comments to an address listed under the
[[Page 68763]]
ADDRESSES section. Include ``Docket No. FAA-2006-26232; Directorate Identifier 2006-CE-62-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this proposed AD. We will consider all comments received by the closing date and may amend this proposed AD because of those comments.
We will post all comments we receive, without change, to http://dms.dot.gov , including any personal information you provide. We will
also post a report summarizing each substantive verbal contact we receive about this proposed AD.
Discussion
The European Aviation Safety Agency (EASA), which is the Technical Agent for the European Community, has issued AD No.: 2006-0189, dated July 4, 2006 (referred to after this as ``the MCAI''), to correct an unsafe condition for the specified products. The MCAI states there was a report of a master cylinder yoke failure. The AD requirements are to detect defective yokes on aircraft and replace them. The aim of this AD is to ensure that normal braking is available at any time to prevent possible runway excursions in the event of failure of the master cylinder yoke. You may obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
EADS SOCATA has issued TBM Aircraft Mandatory Service Bulletin SB 70-136, ATA No. 32, dated December 2005. 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 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 described in a separate paragraph of the proposed AD. These requirements, if ultimately adopted, will take precedence over the actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this proposed AD would affect about 270 products of U.S. registry. We also estimate that it would take about 1.5 work-hours per product to comply with the proposed AD. The average labor rate is $80 per work-hour. Required parts would cost about $600 per product. Where the service information lists required parts costs that are covered under warranty, we have assumed that there will be no charge for these costs. As we do not control warranty coverage for affected parties, some parties may incur costs higher than estimated here. Based on these figures, we estimate the cost of the proposed AD on U.S. operators to be $194,400, or $720 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:
-
Is not a ``significant regulatory action'' under Executive Order 12866;
-
Is not a ``significant rule'' under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); and
-
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.
List of Subjects in 14 CFR Part 39

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
-
The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
-
The FAA amends Sec. 39.13 by adding the following new AD:
EADS SOCATA: Docket No. FAA-2006-26232; Directorate Identifier 2006- CE-62-AD
Comments Due Date
(a) We must receive comments by December 28, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to SOCATA Model TBM 700 airplanes, all serial numbers, certificated in any category.
Reason
(d) The mandatory continuing airworthiness information (MCAI) states there was a report of a master cylinder yoke failure. The AD requirements are to detect defective yokes on aircraft and replace them. The aim of this AD is to ensure that normal braking is available at any time to prevent possible runway excursions in the event of failure of the master cylinder yoke.
[[Page 68764]]
Actions and Compliance
(e) Unless already done, do the following actions.
(1) For the serial numbers indicated below, within the next 100 hours time-in-service or 12 months after the effective date of this AD, whichever occurs first, do the following actions, unless already done:
(i) For airplane serial numbers 269 and 339 and up, check the aircraft records to determine whether cylinder yoke part number ZOO.N7134732200 or the yokes in master cylinder assembly part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281 (right hand side) have been replaced. This check can be done by an owner/ operator holding at least a private pilot certificate as authorized by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7).
(A) If you can positively identify that master cylinder yoke part number ZOO.N7134732200 or the yokes in master cylinder assembly part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281 (right hand side) have been replaced, then you must comply with paragraph (e)(1)(ii) of this AD.
(B) If you can positively identify that master cylinder yoke part number ZOO.N7134732200 or the yokes in master cylinder assembly part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281 (right hand side) have not been replaced, then make an entry in the aircraft records showing compliance with this AD per section 43.9 of the Federal Aviation Regulations (14 CFR 43.9).
(ii) For all airplane serial numbers, unless the action is shown not to apply per paragraph (e)(1)(i)(B) of this AD, inspect for misalignment of the master cylinder yokes from their threaded pins, as instructed in the EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-136, ATA No. 32, dated December 2005, accomplishment instructions paragraph.
(A) If a yoke is found satisfactory, proceed to its re- installation on aircraft.
(B) If a yoke is found defective, prior to further flight, discard the yoke and install a new part number T700A324004810000 (or FAA-approved equivalent part number) yoke in accordance with EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-136, ATA No. 32, dated December 2005.
(2) For all airplane serial numbers, as of the effective date of this AD, do not install part number ZOO.N7134732200 yokes or yokes in master cylinder assembly part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281 (right hand side), unless EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-136, ATA No. 32, dated December 2005, is complied with.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information as follows:
(1) It does not allow interim use of yokes found defective during inspection. FAA policy is to replace defective parts on critical systems.
(2) It applies to all serial numbers. This will assure that, if any of the airplanes had the affected part number yokes installed after delivery of the airplane, the unsafe condition is still addressed. It also will assure that any of the affected part number yokes are inspected per the AD and service bulletin before future installation of these parts.
Other FAA AD Provisions
(f) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Staff, FAA, ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
(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.
