Ainvorthiness Directives; Rolls-Royce pic Turbofan Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule; request for comments. 

SUMMARY: We are adopting a new airworthiness directive (AD) for certain serial 

numbers (SINs) of Rolls-Royce pic (RR) RB2 11-Trent 768-60, 772-60, and 772B-60 

turbofan engines. This AD requires initial and repetitive on-wing or in-shop inspections 

of the high pressure/intermediate pressure (H PIIP) turbine bearing suppo11 oil feed tube 

outer heat shield. This AD also requires installation of a revised HP/IP turbine bearing 

support structure as terminating action to the repetitive inspections of the HPIIP turbine 

bearing support oil feed tube outer heat shield. This AD was prompted by a report of high 

oil consumption due to an oil leak from the 1-IP/IP turbine bearing support oil feed tube. 

We are issuing this AD to prevent failure of the HP turbine disc, uncontained engine 

failure, and damage to the airplane. 

DATES: This AD becomes effective [Insert date 15 days after date of publication in the 

FEDERAL REGISTER].
