Plain English Summary

1/10 complexity

What this does: This Airworthiness Directive (a mandatory safety rule issued by the aviation regulator) requires specific Twin Commander aircraft to physically separate electrical wiring from fuel lines to prevent fires and explosions.

Who it affects: Owners and operators of Twin Commander (also known as Gulfstream/Rockwell/Aero Commander) models 500B, 500U and 500S with serial numbers between 893 and 3115.

What must be done: The aircraft must be modified to ensure electrical wiring is kept away from fuel lines, following the manufacturer's Service Letter No. 240. This work must be completed within 200 hours of flight time after 31 December 1971.

Why it matters: Electrical sparks near fuel lines create a severe fire risk. This rule mandates a physical barrier or distance between potential ignition sources (electrical wiring) and flammable fuel systems to prevent catastrophic accidents.
