Airworthiness Directive 2000-18-03
one-timeAirworthiness Directives; Rolls-Royce plc RB211-524D4 Series Turbofan Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to Rolls-Royce plc models RB211-524D4-19, -524D4-B-19, - 524D4-B-39, -524D4X-19, and 524D4X-B-19 turbofan engines with a cold stream nozzle assembly Part Number (PN) LJ32826 installed. This action requires inspection for cracks and repair of the cold stream nozzle assembly longitudinal flange. This amendment is prompted by a report of the loss of a large section of cold stream nozzle assembly in flight. The actions specified in this AD are intended to detect cracks that could result in failure of the cold stream nozzle assembly, possible release of cold stream nozzle debris from the engine, and possible damage to airplane control surfaces.
Which aircraft AD 2000-18-03 applies to
Inspect cold stream nozzle assemblies (P/N LJ32826, both left and right) for cracks per RR Service Bulletin RB.211-78-C955 Revision 1 (dated June 20, 2000); initial inspection within 60 days or 100 cycles-in-service, repetitive inspections every 1,400 cycles-in-service thereafter. Repair per the SB is optional terminating action for the repetitive inspection requirement.
Whether AD 2000-18-03 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.
