PILATUS Aircraft Ltd. Model PC-7 Airplanes
This AD applies to PILATUS Aircraft Ltd. Model PC-7 airplanes, manufacturer serial numbers (MSN) 101 through 618, 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:
Unless already done, do the following actions:
(1) Within 1 month after December 3, 2010 (the effective date of this AD), check the airplane maintenance records to determine if the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane. Do this check following paragraph 3.A. of Pilatus Aircraft Ltd. PC-7 Service Bulletin No. 57-015, Rev. No. 1, dated July 23, 2010.
(2) If an entry is found during the airplane maintenance records check required in paragraph (f)(1) of this AD or it is unclear whether or not the left and/or right aileron outboard bearing supports have been removed at any time during the life of the airplane, before further flight, do the actions specified in paragraphs 3.A.(2) through paragraph 3.E of Pilatus Aircraft Ltd. PC-7 Service Bulletin No. 57-015, Rev. No. 1, dated July 23, 2010.
Note: This AD differs from the MCAI and/or service information as follows: No differences.
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.
