The Boeing Company Proposes Supersession of Airworthiness Directive AD 2008-13-12 R1 for Certain 737-100 to -500 Series Airplanes

The Boeing Company is proposing to supersede Airworthiness Directive AD 2008-13-12 R1, which requires repetitive inspections for cracking of the upper frame to side frame splice of the fuselage, due to reports of additional fatigue cracking and severed frames, and proposes new modifications and reduced inspection thresholds to detect and correct fatigue cracking and ensure structural integrity.
