AD/FPE/11 - Engine and Auxiliary Power Unit Fire Extinguishers - CANCELLED

What this is: This document officially cancels a previous aviation safety rule (Airworthiness Directive FPE/11) that required fire extinguisher checks in aircraft engines and auxiliary power units.

What the old rule required: Aircraft operators had to inspect or replace certain fire extinguishers within 100 hours of flight time after 24 June 1993.

Why it matters: Because the compliance deadline was a one-time requirement that expired over a decade ago, all affected aircraft have already complied. This cancellation formally removes the obsolete rule from the aviation safety register, cleaning up the regulatory framework.
