Airworthiness Directive 2005-17-11
one-timeAirworthiness Directives; The Cessna Aircraft Company Models 525, 525A, and 525B Airplanes
What this AD requires
The FAA adopts a new airworthiness directive (AD) for certain The Cessna Aircraft Company (Cessna) Models 525, 525A, and 525B airplanes. This AD requires you to install identification sleeves on the wiring for both engine fire extinguisher bottles. This AD results from reports of incorrectly connecting wires to the engine fire extinguisher bottles. We are issuing this AD to prevent incorrect installation of the wires to the engine fire extinguisher bottles, which could result in failure of the engine fire extinguisher bottles to discharge when activated. This failure could lead to the inability to control an engine fire.
Which aircraft AD 2005-17-11 applies to
Whether AD 2005-17-11 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
