Rolls-Royce Deutschland Ltd. & Co KG (formerly Rolls-Royce plc), Models Spey 555-15, 555-15H, 555-15N, and 555-15P Turbojet Engines
This AD applies to Rolls-Royce Deutschland Ltd. & Co KG (RRD) (formerly Rolls-Royce plc), models Spey 555-15, 555-15H, 555-15N, and 555-15P turbojet engines, with magnesium split low pressure (LP) compressor case, part number (P/N) EU.73418A installed. These engines are installed on, but not limited to, Fokker F.28 Mark 1000, Mark 2000, Mark 3000, and Mark 4000 series airplanes.
The FAA is adopting a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd. & Co KG (RRD) (formerly Rolls-Royce plc), models Spey 555-15, 555-15H, 555-15N, and 555-15P turbojet engines, with magnesium split low pressure (LP) compressor case, part number (P/ N) EU.73418A installed. This AD requires replacement of the magnesium split LP compressor case with a serviceable compressor case that is a combination of a steel front LP compressor case and a shortened split compressor case. This AD results from several reports of bird ingestion and LP compressor stage 1 rotor blade failures that have resulted in penetration of the magnesium LP compressor case, and damage to the airplane.
You are responsible for having the actions required by this AD performed within 60 months after the effective date of this AD, unless the actions have already been done.
Remove the magnesium split LP compressor case, P/N EU.73418A, from the engine and install a serviceable LP compressor case. Information on removing and replacing this P/N case can be found in RRD Service Bulletin No. Sp72-893, Revision 3, dated August 25, 2003.
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.
