## Summary

This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD), applicable to Pratt & Whitney (PW) JT8D series turbofan engines. That action would have superseded an existing AD to require initial and repetitive borescope inspections for loss of fuel nozzle nut torque and nozzle support wear, and replacement or modification of the fuel nozzles at the next accessibility of the diffuser build group as terminating action to the inspections. That proposal was prompted by reports of loss of fuel nozzle nut torque and nozzle support wear. Since the issuance of that NPRM, the FAA has reevaluated the likelihood that the unsafe condition will exist or develop on other products of the same type design. Accordingly, the proposed rule is withdrawn.
