Rolls-Royce, plc Models Tay 650-15 and 651-54 Turbofan Engines
Superseded. A later AD replaced this one: AD 2003-22-14. Comply with the one in force.
This airworthiness directive (AD) is applicable to Rolls-Royce, plc (R-R) models Tay 650-15 and 651-54 turbofan engines. These engines are installed on, but not limited to, Fokker Model F.28 Mark 0100 and Boeing 727-QF series airplanes.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
