EADS SOCATA Model TBM 700 Airplanes
This AD applies to Models TBM 700 airplanes, serial numbers 434 through 455, certificated in any category.
We are superseding an existing 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:
Unless already done, do the following before further flight after May 9, 2008 (the compliance date retained from AD 2008-10-13):
(1) Position to “OFF” the air-conditioning “AIR COND” switch.
(2) Inspect for oil leakage in the pulley drive assembly by following EADS SOCATA Service Bulletin (SB) No. 70-156 Amendment 1, dated March 2008.
(i) If any leak is found, before further flight after the inspection, replace the pulley drive assembly part number (P/N) T700G215504900000 with P/N T700G215505710000 following EADS SOCATA Service Bulletin (SB) No. 70-156 Amendment 1, dated March 2008.
(ii) If no leak is found, before further flight, remove the compressor drive belt from the pulley drive assembly following either EADS SOCATA Service Bulletin (SB) No. 70-156, original issue; or EADS SOCATA Service Bulletin (SB) No. 70-156, Amendment 1; both dated March 2008.
(3) The air-conditioning “AIR COND” switch must be in the “OFF” position and the compressor drive belt must remain removed until the pulley drive assembly part number (P/N) T700G215504900000 is replaced with P/N T700G215505710000 following EADS SOCATA Service Bulletin (SB) No. 70-156 Amendment 1, dated March 2008. This replacement must be done before further flight if any leak is found and may be done at any time as terminating action to this AD.
(g) Within the next 12 months after September 23, 2008 (the effective date of this AD), unless already done, replace the pulley drive assembly P/N T700G215504900000 with P/N T700G215505710000 and reinstall the compressor drive belt, following EADS SOCATA Service Bulletin (SB) No. 70-156 Amendment 1, dated March 2008.
