What this law does

This rule requires owners of specific Piper Apache and Aztec aircraft to inspect the fuel lines and electrical wiring located behind the engine firewall.

Who it affects

Owners and operators of Piper PA-23-250 model aircraft with serial numbers between 27-2505 and 27-7954119

What must be done

Inspect the area where the main electrical wiring rubs against fuel lines (this rubbing is called "chafing")
Complete the inspection within 100 hours of flight time after 31 December 1979
Follow the procedures in Piper Service Bulletin No. 663

Why it matters Overseas incidents showed that when electrical wires rub against fuel lines, it can wear holes in the fuel lines causing leaks, and potentially start in-flight engine compartment fires. This safety directive prevents those dangerous situations by mandating an inspection to catch the problem before it causes an accident.
