This AD applies to Aerospatiale Model SN-601 (Corvette) airplanes, certificated in any category, all serial numbers.
We are adopting a new airworthiness directive (AD) for the products listed above. This 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:
Unless already done, do the following actions.
(1) Within 90 days after the effective date of this AD, do a general visual inspection to verify the proper position of the lock washer (located opposite the nut notch) and check the tightening torque of the nut of the shock absorber locking system on both the left-hand and right-hand main landing gear, in accordance with the Accomplishment Instructions of Airbus Corvette Service Bulletin 32-19, dated January 9, 2009.
(2) In case of findings of improper assembly during the inspection required in paragraph (f)(1) of this AD, before further flight, replace the lock washer, install the main landing gear shock absorber body, and install the main landing gear shock absorber, in accordance with the Accomplishment Instructions of Airbus Corvette Service Bulletin 32-19, dated January 9, 2009. Within 120 flight cycles but not before 100 flight cycles, repeat the inspection specified in paragraph (f)(1) of this AD.
(3) In case of no findings during the inspection required in paragraph (f)(1) of this AD, no further inspections are required.
(4) After the effective date of this AD, no person may install a main landing gear shock absorber on which the locking system (nut and lock washer) is not compliant with the approved configuration as identified by Airbus Corvette Service Bulletin 32-19, dated January 9, 2009.
