Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain BAE Systems (Operations) Limited Model BAe 146 and Model Avro 146-RJ airplanes. This proposed AD would require a one-time detailed inspection for corrosion of the hinge bracket assembly of the left and right main landing gear (MLG) doors, and corrective action if necessary. This proposed AD results from in-service reports of hinge bracket failures on the MLG doors. We are proposing this AD to prevent failure of the hinge bracket on the MLG door, which could result in separation of the door, consequent structural damage to the airplane, and possible injury to people on the ground.
