Airworthiness Directives; Pacific Aerospace Limited Airplanes

What this AD requires

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.

Models750XL
Serial-conditional — narrows to serials 193–197, 199–199, 200–200, 203–203.

Applies to (1) all serial numbers equipped with modification PAC/XL/0582, and (2) serial numbers 193 through 197, 199, 200, and 203 regardless of modification status.

Whether AD 2018-07-14 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.
Date — When the work was done.
Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.
Signature & certificate — The A&P/IA who returned it to service, with certificate number.
Is AD 2018-07-14 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
