Airworthiness Directive · Amendment 39-15338 · 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 717-28-0012, Revision 1, dated June 7, 2006.
We are adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires electrical bonding of the fill valves for the right and left main fuel tanks, the fill valve and pipe assembly for the center wing fuel tank, and the defuel shutoff valve. This AD results from a fuel system review conducted by the manufacturer. We are issuing this AD to prevent improper bonding of the fill valves and defuel shutoff valve for the main fuel tanks and center wing tank, which, in combination with a lightning strike, 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 60 months after the effective date of this AD, accomplish the electrical bonding of the fill valves for the right and left main fuel tanks, the fill valve and pipe assembly for the center wing fuel tank, and the defuel shutoff valve, in accordance with the Accomplishment Instructions of Boeing Service Bulletin 717-28-0012, Revision 1, dated June 7, 2006.
Actions accomplished before the effective date of this AD in accordance with Boeing Service Bulletin 717-28-0012, dated April 16, 2004, are considered acceptable for compliance with the corresponding actions specified in paragraph (f) of this AD.
