Airworthiness Directive · Amendment 39-14895 · EADS SOCATA TBM 700 Airplanes
EADS SOCATA TBM 700 Airplanes
This AD applies to SOCATA Model TBM 700 airplanes, all serial numbers, certificated in any category.
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 a report of a master cylinder yoke failure. We are issuing this AD to require actions to correct the unsafe condition on these products.
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:
(i) For airplane serial numbers 269 and 339 and up, check the aircraft records to determine whether the original cylinder yoke or yokes in the master cylinder assembly (both left-hand and right-hand) delivered with the airplane are installed. 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 the original yokes in the master cylinder assemblies (both left-hand and right-hand) delivered with the airplane are installed, 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).
(B) If you cannot positively identify that the original yokes in the master cylinder assemblies (both left-hand and right-hand) delivered with the airplane are installed or if any of the master cylinder yokes have been replaced, then proceed to paragraph (e)(1)(ii) of this AD.
(ii) For all airplane serial numbers, unless the action is shown not to apply per paragraph (e)(1)(i)(A) 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.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
