| Compliance: | As specified in the Requirement document, with a revised effective date of27 October 2005. |
| This Amendment becomes effective on 27 October 2005. | |
| Background: | The FAA received several reports of incidents involving the reinforced flight deck door on certain Model 737-300, -500, and -800 aircraft. In these incidents, slamming the flight deck door caused the decompression latch to release and the decompression panel in the door to open. This Directive requires modification of the upper and lower pressure relief latch assemblies.Amendment 1 is issued in response to a new FAA AD, which was prompted by reports of discrepancies with the reinforced flight deck door. The actions required by this Directive are intended to prevent inadvertent release of the decompression latch and consequent opening of the decompression panel in the flight deck door, or penetration of the flight deck door by smoke or shrapnel, any of which could result in injury to the aircraft flight crew. This Directive also requires detecting and correcting wire chafing, which could result in arcing and consequent fire. |
