Plain English Summary

2/10 complexity

What this is: A safety directive requiring owners of specific Piper aircraft to inspect their fuel pumps regularly to prevent engine failures.

Who it affects: Owners and operators of Piper PA-31P Navajo aeroplanes with serial numbers from 31P-1 to 31P-7400196 (specific older models manufactured up to 1974).

What you must do:

Inspect the submerged fuel pumps (the pumps located inside the fuel tanks) for defects
Complete the first inspection within 100 hours of flying time after 31 July 1974
Repeat this inspection every 100 hours of flying time thereafter
Follow the specific procedures outlined in Piper Service Letter No. 711

Why it matters: Fuel pumps sitting inside fuel tanks can develop faults that cause engine stoppage. Regular inspection prevents accidents by catching problems before they cause failure in flight.
