Airworthiness Directive 2022-03640
one-timeAirworthiness Directives; Continental Aerospace Technologies, Inc. and Continental Motors Reciprocating Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Continental Aerospace Technologies, Inc. C-125, C145, IO-360, IO-470, IO-550, O-300, O-470, TSIO-360, TSIO-520 series model reciprocating engines and certain Continental Motors IO-520 series model reciprocating engines with a certain oil filter adapter installed. This AD was prompted by reports of two accidents that were the result of power loss due to oil starvation. This AD requires replacing the oil filter adapter fiber gasket (fiber gasket) with an oil filter adapter copper gasket (copper gasket). The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2022-03640 applies to
Applies only to the reciprocating engine models identified in paragraphs (c)(1) and (2) of this AD (specific models not given in available text) equipped with an F&M Enterprises, Inc. or Stratus Tool Technologies, LLC oil filter adapter installed per Supplemental Type Certificate SE8409SW, SE09356SC, or SE10348SC.
Whether AD 2022-03640 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:
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.
