Airworthiness Directive 2009-04-03
one-timeAirworthiness Directives; Rolls-Royce Corporation AE 3007A1E and AE 1107C Turbofan/Turboshaft Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Corporation (RRC) AE 3007A1E and AE 1107C turbofan/ turboshaft engines. This AD requires removal from service of certain 2nd stage, 3rd stage, and 4th stage compressor wheels, compressor cone shaft assemblies, and 1st to 2nd-stage turbine spacers at new, reduced, published life limits. This AD results from RRC applying an updated lifing methodology to the affected parts. We are issuing this AD to prevent low-cycle-fatigue failure of the parts listed in Table 1 of this AD, which could result in an uncontained engine failure and damage to the aircraft.
Which aircraft AD 2009-04-03 applies to
Applies only to AE 3007A1E (turbofan) and AE 1107C (turboshaft) engines with the specific compressor wheel, compressor cone shaft assembly, or turbine spacer part numbers in Table 1 installed, each subject to a new reduced life limit; the P/N 23065303 3rd stage compressor wheel is limited to 5,000 cycles (vs. 6,200 generally) only for the listed serial numbers (L72422, L72475, L72505, L130704, L130829, L130830, L138218, L138226, L138621, L206084, L206163).
Whether AD 2009-04-03 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
