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.

Required Actions

Inspect the wiring harness in the rear baggage zone for chafing or contact with the airframe structure. If damage is found, contact ATR for repair instructions and perform the repair. Modify the routing of the electrical wires in the bulkhead area as specified.
