Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all Boeing Model 737-300, -400, and -500 series airplanes. This proposal would require repetitive inspections of certain connectors located in the main wheel wells to detect discrepancies; and corrective action, if necessary. This action is necessary to detect and correct such discrepancies, 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. This action is intended to address the identified unsafe condition.
