AD NUMBER: 2002-16-22
MANUFACTURER: Boeing (CORRECTION)
SUBJECT: Airworthiness Directive 2002-16-22
SUMMARY: This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 727 series airplanes that have been converted from a passenger-to a cargo-carrying (''freighter'')configuration, that requires, among other actions, installation of a fail-safe hinge, redesigned maindeck cargo door warning and power control systems, and 9g crash barrier. This amendment isprompted by the FAA's determination that the main deck cargo door hinge is not fail-safe; thatcertain main deck cargo door control systems do not provide an adequate level of safety; and thatthe main deck cargo barrier is not structurally adequate during an emergency landing. Theactions specified by this AD are intended to prevent structural failure of the main deck cargo door hinge or failure of the cargo door system, which could result in the loss or opening of the cargodoor while the airplane is in flight, and consequent rapid decompression of the airplane, includingpossible loss of flight control or severe structural damage; and to prevent failure of the main deck cargo barrier during an emergency landing, which could injure occupants.
