This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 727, 737, 757-200, 757-200CB, and 757-300 series airplanes. This AD requires modification of the latch assembly of the escape slides. For certain airplanes, this AD also requires installation of a cover assembly on the trigger housing of the inflation cylinder on the escape slides. This action is necessary to prevent failure of an escape slide to deploy or inflate correctly, which could result in the slide being unusable during an emergency evacuation and consequent injury to passengers or airplane crewmembers. 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.
