This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737 series airplanes. This action requires repetitive inspections to detect cracks of the lower gate hinge of the forward galley service door, and replacement of any cracked hinge. This action also provides an optional terminating replacement for the repetitive inspections. This amendment is prompted by reports of fatigue cracks found in the lower gate hinge on the forward galley service door. The actions specified in this AD are intended to prevent such fatigue cracking, which could lead to the failure of the lower gate hinge on the forward galley service door and subsequent loss of cabin pressure. If the hinge fails, the hinge and its associated mechanisms and the emergency escape slide could separate from the airplane and be ingested into the engine, or could strike and damage the flight control surfaces.
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.
