British Aerospace Model Avro 146-RJ85A and RJ100A Series Airplanes: Proposed Airworthiness Directive

Summary

The Federal Aviation Administration (FAA) proposes a new airworthiness directive for certain British Aerospace Model Avro 146-RJ85A and RJ100A series airplanes, requiring a one-time inspection for machining undercuts on the wing's integral stringers and corrective actions if necessary, to prevent reduced wing strength and stiffness.
