## Abstract

This document corrects information in an existing airworthiness directive (AD) that applies to certain Boeing Model 747 series airplanes. That AD currently requires an inspection of the flap drive transmission of the trailing edge flaps at positions 2 and 7 to determine if a discrepant torque brake is installed; and corrective action, if necessary. That AD also imposes certain restrictions on the installation of affected spare parts. This document corrects and clarifies that the spares requirement in paragraph (b) of the final rule applies to only positions 2 and 7 of the trailing edge flaps, as identified in the Boeing service bulletin. This correction is necessary to ensure that operators are made aware that the spares requirement does not apply to positions 4 and 5 of the trailing edge flaps.
