Airworthiness Directive 2013-26-06
one-timeAirworthiness Directives; Rolls-Royce Corporation Turbofan Engines
What this AD requires
We are superseding airworthiness directive (AD) 2010-19-01 for certain Rolls-Royce Corporation (RRC) AE 3007A series turbofan engines. AD 2010-19-01 required removing certain high-pressure turbine (HPT) stage 2 wheels, or performing inspections on them, and reduced their approved life limits. This new AD clarifies the AE 3007A turbofan engine model applicability, further reduces the approved life limits of affected HPT stage 2 wheels, and eliminates the inspections required by the existing AD. This AD was prompted by additional analysis that concluded that lower life limits for the affected HPT stage 2 wheels are necessary. We are issuing this AD to prevent uncontained failure of the HPT stage 2 wheel, damage to the engine, and damage to the airplane.
Which aircraft AD 2013-26-06 applies to
Applies to engines with an installed HPT stage 2 wheel, P/N 23084520; or P/N 23069438, 23069592, 23074462, 23074644, or 23075345, except for HPT stage 2 wheels with a serial number listed in Table 2 through Table 5 of RRC Alert Service Bulletin (ASB) No. AE 3007A-A-72-414, Revision 1, dated December 5, 2012 (those wheels retain their existing approved life limits).
Whether AD 2013-26-06 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.
