Unsafe Condition
Chafed wirings were found in the rear baggage zone, close to the forward side of the aft pressure bulkhead, due to contact with an understructure securing screw. The concerned wiring harness includes rudder trim, pitch trim, and stick pusher control wires. Damages on those wires might lead to the loss of fail-safe criteria for those critical functions, resulting in reduced controllability of the airplane.
