Airworthiness Directive · Amendment 39-12776 · Boeing Model 757-200, -200CB, and -200PF; and 767-200, -300, and -300F Series Airplanes
Boeing Model 757-200, -200CB, and -200PF; and 767-200, -300, and -300F Series Airplanes
Model 757-200, -200CB, and -200PF series airplanes, line numbers 1 through 895 inclusive; and Model 767-200, -300, and -300F series airplanes, line numbers 1 through 759 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200, -200CB, and -200PF; and 767-200, -300, and -300F series airplanes; that requires modification of the right main landing gear and auto-speedbrake control system to provide an air/ground signal to the system. This action is necessary to prevent uncommanded deployment of the auto-speedbrake spoilers during flight, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
