Airworthiness Directives; Boeing Model 757-200 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 757-200 series airplanes, that requires repetitive inspections for fatigue cracking of certain areas of the forward and aft frames of the cargo doorways and repair, if necessary. The actions specified by this AD are intended to find and fix such cracking, which could lead to rapid depressurization of the airplane and result in reduced structural integrity of the cargo doorway. This action is intended to address the identified unsafe condition.
