Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to certain Lockheed Model L-1011-385 series airplanes. That action would have required the replacement of the flap position indicator with an improved flap position indicator. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate that currently there are adequate annunciation provisions and crew procedures to safely detect and accommodate slat drive failures. Accordingly, the proposed rule is withdrawn.
