The FAA has proposed an Airworthiness Directive (AD) for certain Continental engines with an F&M Enterprises Inc. (F&M) or Stratus Tool Technologies LLC (Stratus) oil filter adapter installed. This proposed AD was prompted by reports of two accidents resulting from power loss due to oil starvation.
Continental Aerospace Technologies Inc. C-125, C145, IO-360, IO-470, IO-550, O-300, O-470, TSIO-360 and TSIO-520 series model engines and Continental Motors IO-520 engines may be affected. These engines are used in some Cessna agricultural aircraft. If adopted, the proposed AD would require removing the oil filter adapter fiber gasket and replacing it with a copper gasket. This action would be required before accumulating 50 flight hours after the effective date of the AD or at the next scheduled oil change after the effective date of the AD, whichever comes first.
Comments are due by Nov. 26. You may comment by going to the above link and clicking on the “Submit a Formal Comment” button or other methods outlined in the AD.
