The FAA has revised its proposed Airworthiness Directive (AD) to supersede AD 2022-04-04, which requires replacing the oil filter adapter gasket on certain Continental Aerospace Technologies Inc. engines.
NAAA reported on this in September 2022, when the FAA first proposed an applicability change to AD 2022-04-04 along with expanded replacement gasket part numbers.
This new proposed revision changes the applicability (again) of the AD to include all Continental model engines equipped with an F&M Enterprises Inc. or Stratus Tool Technologies LLC oil filter adapter installed per Supplemental Type Certificate SE8409SW, SE09356SC or SE10348SC. These F&M and Stratus oil filter adapters are known to be installed on Continental Model C–125, C– 145, GO–300, IO–360, IO–470, IO–520, IO– 550, O–300, O–470, TSIO–360 and TSIO– 520 series engines.
This proposed revision would continue to require the replacement of any F&M or Stratus oil filter adapter fiber gasket with a copper gasket part number (P/N) AN900–28 or P/N AN900–29, or a stainless steel PTFE gasket, P/N ST07.
