Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 757 airplanes. This AD was prompted by a report of cracking in the fuselage frame. This AD requires inspections for cracking in the fuselage frame, left and right sides, and repair if necessary. We are issuing this AD to detect and correct fuselage frame fatigue cracking. Such cracking could result in loss of structural integrity and the inability to sustain loading conditions.
