Airworthiness Directives; Continental Aerospace Technologies, Inc. and Continental Motors Reciprocating Engines

FAA / Federal Register · 2021-22095

The FAA proposes to adopt 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 proposed AD was prompted by reports of two accidents that were the result of power loss due to oil starvation. This proposed AD would require removal of the oil filter adapter fiber gasket and its replacement with a copper gasket. The FAA is proposing this AD to address the unsafe condition on these products.
