In plain language (FlightFinder summary)
The Federal Aviation Administration is asked to issue an airworthiness directive covering specific Cessna, Piper, and Robinson aircraft without full-flow engine oil filters. The directive would require installing Avco Lycoming full-flow canister or spin-on oil filter kits following Avco Lycoming Service Instruction No. 1319 B. Installation must occur at the next 100-hour or annual inspection, whichever comes first.
