2017-05242. Airworthiness Directives; CFE Company Turbofan Engines

AGENCY:

Federal Aviation Administration (FAA), DOT.

ACTION:

Proposed rule; withdrawal.

SUMMARY:

The FAA is withdrawing a notice of proposed rulemaking (NPRM). The NPRM proposed a new airworthiness directive (AD) for certain CFE Company (CFE) turbofan engines that published in the Federal Register on January 5, 2017. The proposed action that published in the Federal Register on January 5, 2017 was a duplicate of an NPRM, Directorate Identifier 2016-NE-21-AD, that published in the Federal Register on January 3, 2017. Accordingly, we withdraw the proposed rule that published in the Federal Register on January 5, 2017.

DATES:

As of March 22, 2017, the proposed rule published January 5, 2017 (82 FR 52) is withdrawn.

SUPPLEMENTARY INFORMATION:

The FAA proposed to amend 14 CFR part 39 with a proposed AD (82 FR 1258, January 5, 2017). Since we published the NPRM, Directorate Identifier 2016-NE-21-AD, in the Federal Register on January 5, 2017 (82 FR 1258), we discovered that it was a duplicate of an NPRM, Directorate Identifier 2016-NE-21-AD, that published in the Federal Register on January 3, 2017 (82 FR 52). This duplication created overlapping comment periods with different comment period closing dates, which is confusing to commenters.

Withdrawal of the NPRM (82 FR 1258, January 5, 2017) constitutes only such action, and does not preclude the agency from issuing another notice in the future, nor does it commit the agency to any course of action in the future.

Since this action only withdraws a notice of proposed rulemaking, it is neither a proposed nor a final rule. Therefore, Executive Order 12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979) do not cover this withdrawal.

Issued in Burlington, Massachusetts, on March 8, 2017.
