Airworthiness Directives; Aerospatiale Model ATR 42, et al.; Series Airplanes

摘要

This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to various smaller transport category airplanes certificated for operation with a main deck Class B cargo compartment. That action would have required either the conversion of all main deck Class B cargo compartments to the Class C configuration; or the use of flame penetration-resistant containers with smoke detection and fire extinguishing systems to carry all cargo; or the accomplishment of certain operational and equipment changes and design modifications to maximize cargo fire detection and control. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data and is undertaking alternative rulemaking action. Accordingly, the proposed rule is withdrawn.
