## Summary

This action withdraws a notice of proposed rulemaking that would have added a new airworthiness directive (AD), applicable to CFM International (CFMI) CFM56-3 and -3B series turbofan engines. That action proposed to amend an existing AD and would have required the installation of a riveted oil distributor, Part Number (P/N) 335-305- 804-0. Since the issuance of the NPRM, the manufacturer has advised the Federal Aviation Administration (FAA) that the entire CFM56-3 and -3B fleet has been retrofitted with the new riveted oil distributor, P/N 335-305-804-0, and that there are no oil distributors, P/N 335-305-800- 0, presently in service. The FAA has therefore reviewed its position, and has concluded that the proposed actions are unnecessary. Accordingly, the proposed rule is withdrawn.
