Airworthiness Directives; Boeing Model 777-200, -300, and -300ER Series Airplanes

The FAA is correcting a typographical error in an existing airworthiness directive (AD) that was published in the Federal Register on June 16, 2006 (71 FR 34808). The error resulted in a reference only to the left main fuel tank in paragraph (f)(2) of that AD rather than to both the left and right main fuel tanks. This AD applies to certain Boeing Model 777-200, -300, and -300ER series airplanes. This AD requires a one-time inspection of the first bonding jumper aft of the bulkhead fitting to detect damage or failure and to determine the mechanical integrity of its electrical bonding path, and repair if necessary; measurement of the bonding resistance between the fitting for the fuel feed tube and the front spar in the left and right main fuel tanks, and repairing the bonding if necessary; and application of additional sealant to completely cover the bulkhead fittings inside the fuel tanks.
