ACTION: Final rule; correction. 

SUMMARY: 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. 

DATES: This final rule revision is 

effective January 17, 2012.

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 § 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.

Airworthiness Directives; Rolls-Royce 

plc (RR) RB211–524 Series Turbofan 

Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

the products listed above. That AD 

currently requires initial and repetitive 

borescope inspections of the head 

section and meterpanel assembly of the 

combustion liner, and replacement if 

necessary. This new AD requires those 

same inspections, and replacement. 

This AD also expands the applicability 

to include part numbers (P/N) of 

additional combustion liners. This AD 

was prompted by an inquiry submitted 

by an operator, which resulted in RR 

performing a complete review of the 

affected front combustion liner part 

numbers. We are issuing this AD to 

prevent deterioration of the engine 

combustion liner, which can result in 

combustion liner breakup, case burnthrough, engine fire, and damage to the 

airplane. 

DATES: This AD is effective February 13, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of February 9, 2005 (70 FR 680, 

January 5, 2005). 

ADDRESSES: For service information 

identified in this AD, contact RollsRoyce plc, P.O. Box 31, Derby, DE24 

8BJ, United Kingdom; phone: 011–44– 

1332–242424; fax: 011–44–1332– 

249936, for the service information 

identified in this proposed AD. You

service information at the FAA, Engine 

& Propeller Directorate, 12 New England
