Airworthiness Directive · Amendment 39-15701 · Boeing Model 767-200 and -300 Series Airplanes
Boeing Model 767-200 and -300 Series Airplanes
This AD applies to Boeing Model 767-200 and -300 series airplanes, certificated in any category; as identified in Boeing Alert Service Bulletin 767-28A0064, Revision 2, dated October 27, 2005.
We are adopting a new airworthiness directive (AD) for certain Boeing Model 767-200 and -300 series airplanes. This AD requires replacing the wire segments of the four Fuel Quantity Indicating System (FQIS) wire bundles with new, improved wire segments. This AD results from operator inspections of the FQIS wire bundles that revealed corrosion at the connections between the ground wire and shield of each of the four FQIS wire bundles. We are issuing this AD to prevent this corrosion, which could reduce system protection of the lightning shield and result in loss of the electrical grounding between the lightning shield and the airplane structure. This condition, in combination with flammable fuel vapors, could result in fuel tank explosions 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 36 months after the effective date of this AD: Replace the wire segments of the four FQIS wire bundles with new, improved wire segments, in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 767-28A0064, Revision 2, dated October 27, 2005.
Actions accomplished before the effective date of this AD in accordance with Boeing Alert Service Bulletin 767-28A0064, Revision 1, dated February 21, 2002, are considered acceptable for compliance with the corresponding actions specified in this AD.
