AD NUMBER: 2006-25-13
MANUFACTURER: Rolls Royce
SUBJECT: Airworthiness Directive 2006-25-13
SUMMARY: The FAA is adopting a new airworthiness
directive (AD) for Rolls-Royce Corporation (RRC) AE2100D3 turboprop
This AD requires removing certain part number (P/N) compressor
cone shaft assemblies at a new reduced cyclic life limit of 5,000
This AD results from low-cycle-fatigue testing and analysis of
certain P/N compressor cone shaft assemblies, by RRC.
We are issuing this AD to prevent uncontained failure of the
compressor cone shaftassembly, leading to engine shutdown and
damage to the airplane.
