Unsafe condition

This AD results from both the need to protect aircraft wiring left unprotected in the original design and a report of a Model 525B airplane experiencing in-flight loss of numerous systems, tripped circuit breakers, and burned wiring adjacent to the power distribution panel. We are issuing this AD to correct an incorrect wiring installation and to provide short-circuit protection for all wiring from the aircraft power distribution system. This condition could result in burned wiring and loss of various aircraft electrical systems.
