## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for Rolls-Royce Deutschland Ltd. & Co KG (RRD), 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 proposed AD would require 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 proposed AD results from several reports of bird ingestion and LP stage 1 rotor blade failures that have resulted in penetration of the magnesium LP compressor case, and damage to the airplane. We are proposing this AD to prevent possible uncontained LP stage 1 rotor blade failures that could result in damage to the airplane.
