Airworthiness Directive · Amendment 39-15342 · McDonnell Douglas Model 717-200 Airplanes
McDonnell Douglas Model 717-200 Airplanes
This AD applies to McDonnell Douglas Model 717-200 airplanes, certificated in any category; as identified in Boeing Service Bulletin 717-28-0007, Revision 1, dated September 23, 2003.
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires modification of the conduit for the forward boost pump of the center fuel tank. This AD results from the finding that a potential chafing condition exists in the volute assembly of the forward boost pump for the center fuel tank. We are issuing this AD to prevent chafing of the fuel boost pump wiring that could lead to arcing to the inside of the 45-degree angle fitting, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 78 months after the effective date of this AD, modify the conduit for the forward fuel boost pump of the center fuel tank, by accomplishing all of the actions specified in Boeing Service Bulletin 717-28-0007, Revision 1, dated September 23, 2003.
Actions done before the effective date of this AD in accordance with Boeing Service Bulletin 717-28-0007, dated August 22, 2002, are acceptable for compliance with the requirements of paragraph (f) of this AD provided that a leak check of the conduit is accomplished in accordance with Boeing 717 Airplane Maintenance Manual (AMM) Task 28-22-28-700-801, “Leak Test of the Fuel Pump Electrical Conduit.”
