NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE APPLICABLE TO PIPER PA-31 SERIES AIRPLANES REQUIRING, AT THE NEXT SCHEDULED INSPECTION OR DISSASSEMBLY OF THE AILERON CONTROL SYSTEM, WHICHEVER OCCURS FIRST, AN INSPECTION OF THE AILERON BALANCE CABLE TERMINALS AND BELLCRANK LUGS. IF THE RED COLOR CODING OF THESE COMPONENTS HAS DETERIORATED, IT SHOULD BE REPLACED. IF RED COLOR CODING HAD NEVER BEEN INSTALLED, IT SHOULD BE INCORPORATED AND, WHERE APPLICABLE, THE SERVICE MANUALS AMENDED TO REFLECT THIS SUPPLEMENTAL MEANS OF VERIFYING CORRECT INSTALLATION OF AILERON CABLES.
In plain language (FlightFinder summary)
The FAA is asked to issue an airworthiness directive for Piper PA-31 series airplanes. The directive would require inspecting aileron balance cable terminals and bellcrank lugs at the next scheduled inspection or aileron control system disassembly, and if the red color coding is deteriorated or missing, it must be replaced or incorporated, with service manuals amended accordingly.
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.
