SUPPLEMENTARY INFORMATION: 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 Sec. 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.
