Summary
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.
