Airworthiness Directives; The Cessna Aircraft Company Models 525, 525A, and 525B Airplanes

Riepilogo

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.
