Airworthiness Directive 2003-14-23
one-timeAirworthiness Directives; Rolls-Royce plc RB211-524G2, -524G2-T, -524G3, -524G3-T, -524H, -524H-T, -524H2, and -524H2-T Series, and Models RB211 Trent 768-60, 772-60, and 772B-60 Turbofan Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce plc (RR) RB211-524G2, -524G2-T, -524G3, -524G3-T, -524H, - 524H-T, -524H2, and -524H2-T series, and models RB211 Trent 768-60, 772-60, and 772B-60 turbofan engines with high pressure compressor (HPC) rotor stage 1 through stage 6 drums, part numbers (P/Ns) FK25502 and FW20195 installed. This AD is prompted by reports of cracks found in loading slots of HPC rotor stage 1 through stage 6 drums. We are issuing this AD to prevent crack initiation and propagation leading to uncontained failure of the HPC rotor stage 1 through stage 6 drum, and damage to the airplane.
Which aircraft AD 2003-14-23 applies to
Applies only to engines with HPC rotor stage 1 through stage 6 drums, P/N FK25502 or FW20195, installed; engines installed on, but not limited to, Airbus A330, Boeing 747-400, and 767-300 series airplanes.
Whether AD 2003-14-23 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.
