Airworthiness Directive · Amendment 39-21188 · Flight controls
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Model 750XL airplanes, serial numbers 101 through to 215, 220, 8001, and 8002, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for certain Pacific Aerospace Limited Model 750XL 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 an incorrect illustration of the screw jack assembly in the airplane maintenance manual, which may cause potential errors with installation. The FAA is issuing this AD to address the unsafe condition on these products.
Unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD.
(1) Within 20 hours time-in-service after September 2, 2020 (the effective date of this AD), inspect the left hand (LH) and right hand (RH) flap screw jack assemblies for proper installation by following the Accomplishment Instructions, paragraphs A.1) through A.3), of Pacific Aerospace Mandatory Service Bulletin (MSB) PACSB/XL/117, Issue 2, dated August 21, 2019 (PACSB/XL/117, Issue 2). If a flap screw jack assembly is not properly installed as shown in figures 1 and 2 of PACSB/XL/117, Issue 2, before further flight, comply with the Accomplishment Instructions, Part B, of PACSB/XL/117, Issue 2.
(2) As of September 2, 2020 (the effective date of this AD), do not install a LH flap screw jack assembly P/N 11-45621-1 or RH flap screw jack assembly P/N 11-45622-1 on any airplane, unless it is installed in accordance with the Accomplishment Instructions, Part B, of PACSB/XL/117, Issue 2.
