Rolls-Royce Deutschland Ltd. & Co. KG. (RRD) Tay 650-15 Turbofan Engines
Superseded. A later AD replaced this one: AD 2010-17-12. Comply with the one in force.
This AD applies to RRD Tay 650-15 turbofan engines that have a serial number listed in Table 1 or Table 2 of this AD, and low-pressure (LP) turbine module M05300AA installed. These engines are installed on, but not limited to, Fokker F28 Mark 0100 airplanes.

We are superseding an existing airworthiness directive (AD) for the products listed above. That AD currently requires initial and repetitive inspections of the low-pressure (LP) turbine discs stage 2 and stage 3 for corrosion, on certain serial number engines. This AD requires the same actions, but extends the applicability to additional engine serial numbers. This AD results from mandatory continuing airworthiness information (MCAI) issued by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Prior to accumulating 11,700 flight cycles (FC) since new, and thereafter at intervals not exceeding 11,700 FC of the engine, inspect the LP turbine disks stage 2 and stage 3 for corrosion in accordance with RRD Alert Service Bulletin No. TAY-72-A1524, Revision 2, dated June 13, 2008.
(2) For engines that already exceed 11,700 FC on the effective date of this AD, perform the inspection within 90 days after the effective date of this AD.
(3) When, during any of the inspections as required by paragraph (e)(1) of this directive, corrosion is found, replace the affected parts. The RRD TAY 650 Engine Manual—E-TAY-3RR, Tasks 72-52-23-200-000 and 72-52-24-200-000 contains guidance on performing the inspection for corrosion and rejection criteria.
Initial inspections done before the effective date of this AD on LP turbine disks stage 2 and stage 3 listed in Table 1 of this AD using RRD Alert Service Bulletin No. TAY-72-A1524, Revision 1, dated September 1, 2006, comply with the initial inspection requirements specified in this AD.
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.
