Airworthiness Directive 2001-22-18
recurringAirworthiness Directives; Rolls-Royce, plc Models Tay 650-15 and 651-54 Turbofan Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), that is applicable to Rolls-Royce, plc models Tay 650-15 and 651-54 turbofan engines. This amendment requires initial and repetitive visual and ultrasonic inspections of fan blades for cracks, and, if necessary, replacement with serviceable parts. In addition, this AD requires recording instances when engines are operated in a stabilized manner in newly prohibited ranges. This amendment is prompted by reports of fan blade failures. The actions specified by this AD are intended to prevent fan blade failures, which can result in an uncontained engine failure, engine fire, and damage to the airplane.
Which aircraft AD 2001-22-18 applies to
Applies to Rolls-Royce Tay 650-15 and 651-54 turbofan engines; requires recordkeeping of stabilized operation in prohibited N1 ranges (per RR SB Tay-72-1447) and initial/repetitive fan blade inspections (per RR SB Tay 72-1442) to prevent fan blade cracking/failure.
Whether AD 2001-22-18 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.
