Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to all BAE Systems (Operations) Limited (Jetstream) Model 4101 airplanes. That action would have required revising the airplane flight manual to advise the flightcrew of special operating limitations associated with a reduction in airplane performance due to loss of propeller efficiency. That action also would have required installing placards in the flight compartment and operating the airplane per certain special operating limitations; or performing repetitive flight checks to verify the adequacy of the airplane's climb performance, and accomplishing follow-on actions if necessary. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has issued another NPRM applicable to certain propellers, which addresses the identified unsafe condition. Accordingly, the proposed rule is withdrawn.
