Final rule; correction.


The FAA is correcting an airworthiness directive (AD) that was published in the Federal Register. That AD applies to Turbomeca Arriel 1 series turboshaft engines. The AD number is incorrect in the preamble and in the Regulatory text. This document corrects those errors. In all other respects, the original document remains the same.


This final rule revision is effective January 17, 2012.


You may examine the AD docket on the Internet at; or in person at the Docket Management Facility between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains this AD, the regulatory evaluation, any comments received, and other information. The address for the Docket Office (phone: (800) 647-5527) is Document Management Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590.

Airworthiness Directive 2011-26-02, Amendment 39-16892 (76 FR 77378, December 13, 2011), currently requires removing from service certain gas generator second stage turbine discs, part number (P/N) 0 292 25 040 0, that are not marked with “CFR” before the discs exceed 4,000 cycles-in-service (CIS) since new. That AD also requires removing from service certain gas generator second stage turbine discs, P/N 0 292 25 040 0, that are marked with “CFR” before the discs exceed 6,500 CIS since new.

As published, the AD number 2011-26-02 in the preamble of the AD and under § 39.13 [Amended], is incorrect.

No other part of the preamble or regulatory information has been changed; therefore, only the changed portion of the final rule is being published in the Federal Register.

The effective date of this AD revision remains January 17, 2012.
