Airworthiness Directives; Boeing Model 737-100, -200, -200C Series Airplanes

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 737-100, -200, and -200C series airplanes. This action requires repetitive inspections to detect fatigue cracking and certain discrepancies of the forward engine mount support (FEMS) fitting and its attachments, and repair, if necessary. This amendment is prompted by reports of fatigue cracks on the lower flange of the FEMS fitting, broken bolts and bolts with loose or detached nuts on the upper inboard attachment of the FEMS fitting, and cracked or severed lugs at the outboard support link attachment of the FEMS fitting. The actions specified in this AD are intended to detect and correct fatigue cracking and certain discrepancies of the FEMS fitting and its attachments, which could result in an in-flight separation of an engine.
