Airworthiness Directive 2004-04-05
recurringAirworthiness Directives; Rolls-Royce Corporation (Formerly Allison Engine Company) AE 3007 Series Turbofan Engines
What this AD requires
The FAA is superseding an existing airworthiness directive (AD) for Rolls-Royce Corporation (RR) (formerly Allison Engine Company) AE 3007A, AE 3007A1/1, AE 3007A1/2, AE 3007A1, AE 3007A1/3, AE 3007A1P, and AE 3007A3 turbofan engines. That AD currently requires initial and repetitive inspections for bearing material contamination of the engine oil system. This AD requires the same inspections but with an extended repetitive inspection interval, and adds terminating actions to the repetitive inspections required by this AD. This AD is prompted by design changes introduced by the manufacturer that reduce the axial load on the No. 1 bearing. We are issuing this AD to prevent the rapid failure of the No. 1 bearing, which could result in smoke in the cabin and an uncommanded in-flight engine shutdown.
Which aircraft AD 2004-04-05 applies to
Formerly Allison Engine Company; engines installed on, but not limited to, Embraer EMB-145, EMB-145ER, EMB-145MR, EMB-145LR, EMB-135ER, and EMB-135LR airplanes
Whether AD 2004-04-05 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.
