Airworthiness Directive · Amendment 39-15866 · 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 Alert Service Bulletin 717-29A0009, dated July 31, 2008.
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires modifying the wire installation of the auxiliary hydraulic pump in the right wheel well of the main landing gear (MLG). This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent a tire burst when the MLG is in the retracted position from causing damage to the wire assembly of the auxiliary hydraulic pump and subsequent electrical arcing, creating the potential of an ignition source to the center wing tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Comply with this AD within the compliance times specified, unless already done.
Within 60 months after the effective date of this AD: Modify the wire installation of the auxiliary hydraulic pump in the right wheel well of the MLG by doing all the applicable actions specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 717-29A0009, dated July 31, 2008.
