Airworthiness Directive · Amendment 39-15255 · Boeing Model 767-200, -300, and -300F Series Airplanes
Boeing Model 767-200, -300, and -300F Series Airplanes
This AD applies to Boeing Model 767-200, -300, and -300F series airplanes, certificated in any category; as identified in Boeing Special Attention Service Bulletin 767-28-0087, dated February 5, 2007.
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 767-200, -300, and -300F series airplanes. This AD requires a one-time inspection of each fuel quantity indication system (FQIS) wire harness connector for corrosion of the shield-to-backshell connection, corrosion on the ground jumper, and damage to the ground jumper; a loop resistance test of each FQIS wire harness; and related investigative and corrective actions if necessary. This AD results from reports of corrosion of the out-tank wire harness of the spar connector backshell for the FQIS. We are issuing this AD to detect and correct corrosion of the out-tank wire harness, which could prevent correct grounding of the lightning shield and result in total 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 48 months after the effective date of this AD, do the actions in paragraphs (f)(1) and (f)(2) of this AD, and do all applicable related investigative and corrective actions, by accomplishing all the actions specified in the Accomplishment Instructions of Boeing Special Attention Service Bulletin 767-28-0087, dated February 5, 2007. Do all applicable related investigative and corrective actions before further flight.
(1) A detailed inspection of each FQIS wire harness connector for corrosion of the shield-to-backshell connection, corrosion on the ground jumper, and damage to the ground jumper.
(2) A loop resistance test of each FQIS wire harness.
Note 1: Boeing Special Attention Service Bulletin 767-28-0087, dated February 5, 2007, refers to Cinch Service Bulletin CN1156-28-02 as an additional source of service information for installing a backshell and assembly upgrade kit.
