Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Turbofan 

Engines 

AGENCY: Federal Aviation Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new airworthiness directive (AD) for certain RollsRoyce Deutschland Ltd & Co KG (RRD) Tay 611-8 turbofan engines. This AD requires 

inspection and replacement, if necessary, of affected bolts. This AD was prompted by a 

quality review determination that bolts with reduced material properties may have been 

installed in some engines. We are issuing this AD to prevent uncontained turbine disc 

fracture and damage to the airplane. 

DATES: This AD becomes effective [Insert date 35 days after date of publication in the 

FEDERAL REGISTER]. 

ADDRESSES: The Docket Operations office is located at Docket Management Facility, 

U.S. Department of Transportation, 1200 New Jersey Avenue SE., West Building Ground 

Floor, Room Wl2-140, Washington, DC 20590-0001.
