Airworthiness Directives; Boeing Model 747 Series Airplanes

This document corrects information that appeared in airworthiness directive (AD) 97-25-06, amendment 39-10230, that was published in the Federal Register on December 1, 1997 (62 FR 63622). The error resulted in an advertent omission in reference to acceptable replacement components. This AD, applicable to certain Boeing Model 747 series airplanes, requires disconnection of the electrical connector to the scavenge pump of the center wing tank. This AD also requires a one- time inspection to identify the part number of the electrical connector; and replacement of the pump with a new or serviceable pump, if necessary.
