Airworthiness Directive · Amendment 39-14854 · Rolls-Royce Corporation AE 2100D3 Turboprop Engines
Rolls-Royce Corporation AE 2100D3 Turboprop Engines
This AD applies to Rolls-Royce Corporation (RRC) AE 2100D3 turboprop engines with a compressor cone shaft assembly, part number 23050728, 23070729, or 23076017, installed. These engines are installed on, but not limited to, Lockheed Martin C-130J military transport airplanes.
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 2100D3 turboprop engines. This AD requires removing certain part number (P/N) compressor cone shaft assemblies at a new reduced cyclic life limit of 5,000 engine cycles. 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 shaft assembly, leading to engine shutdown and damage to the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified unless the actions have already been done.
After the effective date of this AD, remove compressor cone shaft assemblies from service at the new reduced life limit of 5,000 engine cycles.
