Plain English Summary

2/10 complexity

What this is: A safety rule (Airworthiness Directive) for Piper PA-25 Pawnee agricultural aircraft.

Who it affects: Owners and operators of PA-25 and PA-25-235 model aeroplanes and their variants.

What it requires: You must replace the flexible fuel hose connecting the fuel filter to the carburettor (the device mixing fuel and air for the engine) with an approved fire-resistant hose assembly.

Why it matters: Ordinary rubber fuel lines can melt or burst if exposed to engine heat or fire, causing catastrophic in-flight fires. This modification ensures the fuel line can withstand high temperatures long enough for the pilot to detect the problem and land safely.
