This AD was prompted by the development of a modification intended to address the unsafe condition. We are issuing this AD to detect and correct discrepancies of certain connectors located in the main wheel well. Those discrepancies 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.
