Airworthiness Directives; Boeing Model 767 Series Airplanes

This document corrects information in an existing airworthiness directive (AD) that applies to all Boeing Model 767 series airplanes. That AD currently requires repetitive inspections to detect discrepancies of the wiring and surrounding Teflon sleeves of the fuel tank boost pumps and override/jettison pumps; replacement of the sleeves with new sleeves, for certain airplanes; and repair or replacement of the wiring and sleeves with new parts, as necessary. This document corrects the date for the relevant service information referenced in that AD. This correction is necessary to ensure that operators use the correct source of service information to accomplish the actions required by the existing AD, which are intended to ensure adequate protection from chafing for the fuel pump wire insulation.
