In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an airworthiness directive for airplanes with Cessna Aircraft Company spin-on oil filter adapter P/N 1250922 or similar designs. The directive would require periodic inspection of torque paint or putty during oil changes, and if broken or misaligned, reinspect the adapter-to-oil pump threads, verify torque, and reapply torque paint or putty as outlined in previous recommendations.
This plain-language summary is written by FlightFinder to explain the recommendation above. It is not the official wording — the verbatim NTSB text is quoted above.
