Plain English Summary

1/10 complexity

What it is: A mandatory safety instruction (called an Airworthiness Directive) for owners and operators of specific Piper agricultural aircraft.

What it requires: If you operate a Piper PA-25 "Pawnee" aircraft fitted with specific rubber-lined fuel cells (part number 64747-00), you must modify the fuel cell vent system according to Piper Service Bulletin No. 247.

When it had to be done: Within 100 hours of flying time after 25 January 1968.

Why it matters: This prevents potential fuel system failures—critical for safety since the PA-25 is often used for crop-dusting and aerial application work where fuel leaks or ventilation problems could cause crashes or fires.
