Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to all Saab Model SAAB SF340A and SAAB 340B series airplanes. That action would have required modifying or replacing flight data recorders (FDR) of a certain model. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that the identified unsafe condition has been corrected on all airplanes that would have been subject to the NPRM. Accordingly, the proposed rule is withdrawn.
