Airworthiness Directive · Amendment 39-14088 · Boeing Model 737-300, -400, and -500 Series Airplanes
Boeing Model 737-300, -400, and -500 Series Airplanes
This AD applies to all Boeing Model 737-300, -400, and -500 series airplanes, certificated in any category.
The FAA is superseding an existing airworthiness directive (AD), which applies to all Boeing Model 737-300, -400, and -500 series airplanes. That AD currently requires repetitive inspections of certain connectors located in the main wheel well to detect discrepancies, and corrective action if necessary. This new AD instead mandates a modification. This AD is prompted by the development of a modification intended to address the unsafe condition. We are issuing this AD to prevent 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.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
At the applicable time specified in paragraph (f)(1) or (f)(2) of this AD: Modify the electrical connectors located in the main wheel well by doing all the actions in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 737-28-1196, Revision 3, dated April 1, 2004. Any corrective action must be done before further flight in accordance with the service bulletin.
(1) For airplanes on which no inspection required by AD 2001-14-06 has been done as of the effective date of this AD: Accomplish the modification within 12 months after the effective date of this AD.
(2) For airplanes on which any inspection required by AD 2001-14-06 has been done as of the effective date of this AD: Accomplish the modification at the later of the times specified in paragraph (f)(2)(i) or (f)(2)(ii) of this AD.
(i) Within 18 months after accomplishing the last inspection.
(ii) Within 6 months after the effective date of this AD.
Modifications done before the effective date of this AD in accordance with Boeing Special Attention Service Bulletin 737-28-1196, dated December 5, 2002; Revision 1, dated March 13, 2003; or Revision 2, dated August 21, 2003; are considered acceptable for compliance with paragraph (f) of this AD.
