Superseded. A later AD replaced this one: AD 2012-10-12. Comply with the one in force.
This AD applies to Rolls-Royce plc RB211 Trent 553-61, 553A2-61, 556-61, 556A2-61, 556B-61, 560-61, 560A2-61, 768-60, 772-60, 772B-60, 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 turbofan engines.

We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions:
(1) Applicable to RR Trent 800 engines not previously inspected per Rolls-Royce RB211 Propulsion System Alert Non Modification Service Bulletin RB.211-72-AF260, Revision 2, dated July 4, 2007; or earlier issue: Within 400 flight cycles of the Effective Date of this AD inspect the IP Compressor rotor rear balance land for cracks in accordance with Rolls-Royce RB211 Propulsion System Alert Non Modification Service Bulletin RB.211-72-AF313, dated February 22, 2007 section 3 Accomplishment Instructions. Engines on which cracking is found should be rejected from service.
(2) Applicable to RR Trent 500, 700 and 800 engines at each shop visit in which the engine is sufficiently disassembled to access the IP Compressor Module rear face: Inspect the IP Compressor rotor rear balance land for cracks in accordance with Rolls-Royce RB211 Propulsion System Alert Non Modification Service Bulletin RB.211-72-AF260, Revision 2, dated July 4, 2007; or earlier issue section 3 Accomplishment Instructions.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
