Unsafe condition
This AD was prompted by a fatal accident where evidence of thermal damage in the area below the main circuit breaker panel was found. We are issuing this AD to detect and correct rubbing/chafing of wiring with other wires, adjacent structure, and/or flammable fuel lines, which could lead to electrical arcing and possible inflight fire in an area that is not accessible by the crew.
Affected ADs
None.
