Airworthiness Directive · Amendment 39-19245 · Flight controls
Pacific Aerospace Limited Airplanes
This AD applies to the following Pacific Aerospace Limited Model 750XL airplanes, certificated in any category:
(1) All serial numbers equipped with modification PAC/XL/0582; and
(2) serial numbers 193 through 197, 199, 200, and 203.
We are 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 insufficient engagement of the couplings with the flex drive of the rudder trim drive system. We are issuing this AD to require actions to address the unsafe condition on these products.
Unless already done, within 60 days after April 30, 2018 (the effective date of this AD), remove the rudder and elevator drive shaft couplings, part number (P/N) 11-49023-1, and replace with P/N 11-49023-3 at fuselage stations 115.34 and 180.85, ensuring proper engagement of the drive ends. Follow the Accomplishment Instructions in Pacific Aerospace Mandatory Service Bulletin PACSB/XL/085, Issue 1, dated January 8, 2018.
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.
