Airworthiness Directive · Amendment 39-21205 · Engine oil
Pacific Aerospace Limited Airplanes
This AD applies to Pacific Aerospace Limited Model 750XL airplanes, all serial numbers up to 217, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) AD 2018- 04-09 for Pacific Aerospace Limited Model 750XL airplanes. 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 incorrectly marked and annunciated low oil- pressure indication warnings. 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) through (4) of this AD, as applicable:
