Airworthiness Directives; The Boeing Company Model 757 Airplanes

요약

The FAA is adopting a new airworthiness directive (AD) for Model 757-200, -200PF, -200CB, and -300 series airplanes. This AD requires an inspection of the two spring arms in the spin brake assemblies in the nose wheel well to determine if the spring arms are made of aluminum or composite material, and repetitive related investigative/corrective actions if necessary. This AD also provides options for terminating the repetitive actions. This AD results from reports of cracked and broken aluminum springs. We are issuing this AD to detect and correct cracked or broken springs. A cracked or broken spring could separate from the airplane and result in potential hazard to persons or property on the ground, or ingestion into the engine with engine damage and potential shutdown, or damage to the airplane.
