Boeing Proposes Airworthiness Directive for 737-100, -200, and -500 Series Airplanes to Detect Fatigue Cracking

Summary

Boeing is proposing an airworthiness directive to add inspections for cracks in the outboard chord of the frame and the radius of the auxiliary chord on certain 737-100, -200, and -500 series airplanes, in order to detect and correct fatigue cracking that could lead to reduced structural integrity and rapid decompression of the aircraft.
