SUBJECT CATEGORY: Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes DATES: This AD becomes effective March 23, 2007.
DOCUMENT 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 cracks found on several main landing gear cylinders. We are issuing this AD to require actions to correct the unsafe condition on these products.
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 decisionmaking responsibilities to identify and correct unsafe conditions on U.S.certificated products. This AD references the MCAI and related service information that we considered in forming the engineering basis to correct the unsafe condition. The AD contains text copied from the MCAI and for this reason might not follow our plain language principles.
Comment Issue No. 1: Change the Required Parts Cost in the Compliance Section EADS SOCATA comments the cost for the parts required to do the actions in the proposed AD are totally out of proportion. EADS SOCATA states the application of SB 70130, ATA No. 32, dated January 2006, requires only two cotter pins and this cost is negligible. The proposed AD states it will take approximately $125,600 to comply with the AD.
In our cost estimate, we grouped all actions required to comply with the AD, including replacement of any MLG found cracked. We have since learned from EADS SOCATA that labor and parts costs for any cracked MLG will be provided under warranty. We will modify the Costs of Compliance section to reflect the 3 workhours to do the inspection and the warranty coverage for the replacement MLG.
Comment Issue No. 2: Change the Number of WorkHours in the Compliance Section EADS SOCATA comments they have established, by applying the service bulletin, it takes 2 workhours per product to perform an eddy current inspection, and it takes 3 workhours per product to perform a dye penetrant or fluorescent penetrant inspection. The proposed AD states it will take approximately 18 workhours to comply with the AD. In our cost estimate, we grouped all actions required to comply with the AD, including replacement of any MLG found cracked. We have since learned from EADS SOCATA that labor and parts costs for any cracked MLG will be provided under warranty. We will modify the Costs of Compliance section to reflect the 3 workhours to do the inspection and the warranty coverage for the replacement MLG.
EADS SOCATA comments that SB 70130, ATA No. 32, dated January 2006, specifies for MLG with forging body totaling more than 3,500 landings to inspect the forging body within 25 landings after issuance of the service bulletin. However, the proposed AD lowers the limit to 3,475 landings. EADS SOCATA states the limit of 3,500 landings was established by analysis considering all necessary margins. EADS SOCATA requests the FAA change paragraph (e)(2) to read, ``For MLG with forging body totaling more than 3,500 landings:'' or explain the reason for the difference in the FAA AD Differences section.
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 a U.S. court of law. 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 described in a separate paragraph of the AD. These requirements, if any, take precedence over the actions copied from the MCAI. Costs of Compliance We estimate that this AD will affect 272 products of U.S. registry. We also estimate that it will take about 3 workhours per product to comply with the basic requirements (inspection) of this AD. The average labor rate is $80 per workhour. Based on these figures, we estimate the cost of the basic requirements of this AD to the U.S. operators to be $65,280, or $240 per product. In addition, followon actions (possible MLG replacement) would be covered by EADS SOCATA under warranty (both parts and labor). We have no way of determining the number of airplanes that would need this action.
(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.

20070413 EADS SOCATA: Amendment 3914945; Docket No. FAA2006 26235; Directorate Identifier 2006CE65AD. Effective Date
(a) This airworthiness directive (AD) becomes effective March 23, 2007. [[Page 7578]] Affected ADs (b) None. Applicability
(c) This AD applies to Model TBM 700 airplanes, serial numbers 1 through 9999, certificated in any category. Reason
(d) The mandatory continuing airworthiness information (MCAI) states reports of cracks found on several main landing gear (MLG) cylinders. If not detected and corrected, fatigue cracks in the shock strut cylinder of the MLG could result in a collapsed MLG during takeoff or landing, and possible reduced structural integrity of the airplane. Actions and Compliance (e) Unless already done, do the following actions.
(i) Inspect the forging body for cracks within 100 landings after March 23, 2007 (the effective date of this AD) in accordance with the accomplishment instructions of EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70130, ATA No. 32, dated January 2006.
(i) Inspect the forging body for cracks within 25 landings after March 23, 2007 (the effective date of this AD) in accordance with the accomplishment instructions of EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70130, ATA No. 32, dated January 2006.
(4) If you do not know the number of landings, follow the instructions in the Compliance section of EADS SOCATA TBM Aircraft Mandatory Service Bulletin SB 70130, ATA No. 32, dated January 2006.
