Airworthiness Directives; Boeing Model 737 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 737 series airplanes, that requires a one-time detailed visual inspection of the upper decompression panel on the flight deck door to verify that a minimum overlap dimension exists, and corrective action, if necessary. This amendment is prompted by reports indicating that, during production, some upper decompression panels were installed incorrectly on the flight deck door. The actions specified by this AD are intended to detect an incorrectly installed upper decompression panel, which could cause the emergency exit panel on the flight deck door to become inoperable, thereby preventing crewmembers from performing essential duties during an emergency evacuation.
