## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to all Boeing Model 737-300, -400, and -500 series airplanes, that requires repetitive inspections of certain connectors located in the main wheel wells to detect discrepancies; and corrective action, if necessary. This amendment is prompted by reports indicating engine shutdown during flight due to uncommanded movement of the engine shutoff valve. These actions are necessary to detect and correct discrepancies of certain connectors located in the main wheel wells, which could result in electrical arcing of the connectors, uncommanded closure of the engine fuel shut-off valves, and consequent in-flight loss of thrust or engine shutdown from lack of fuel.
