Airworthiness Directive · Amendment 39-18601 · Flight controls
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Models FU24-954 and FU24A-954 airplanes, all serial numbers, that are:
(1) Equipped with an elevator torque tube, part number (P/N) 242837, 242527, 242835, or 242646; and
(2) Certificated in any category.
We are adopting a new airworthiness directive (AD) for Pacific Aerospace Limited Models FU24-954 and FU24A-954 airplanes. This AD results from mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracked elevator torque tubes. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, do the following actions.
(1) Within the next 25 hours time-in-service after September 8, 2016 (the effective date of this AD), do a detailed visual inspection of the elevator torque tube for cracks.
(2) Before further flight after the inspection required in paragraph (f)(1) of this AD, replace the elevator torque tube with a serviceable elevator torque tube if any cracks are found. Do the replacement following Chapter 27, Flight Controls, dated May 1980, of the Maintenance Manual for the Fletcher FU24 and FU24A Post-954, Pacific Aerospace Corporation, Ltd.
Note 1 to paragraph (f) of this AD: This AD does not affect the required repetitive inspections of the control column/elevator torque tubes as specified in the FAA-approved maintenance program.
