This AD results from a report of smoke and fumes in the cockpit of a Model 737-300 series airplane. We are issuing this AD 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, any of which could result in injury to the airplane flightcrew. We are also issuing this AD to detect and correct wire chafing, which could result in arcing, fire, and/or reduced controllability of the airplane.
