## Discrepancy

PILOT WENT TO START NR 1 ENGINE. ENGINE WOULD NOT TURN. FOUND ENGINE SEIZED. REMOVED AND REPLACED ENGINE ASSEMBLY.  BROUGHT ENGINE TO ARC, DISASSEMBLED ENGINE AND FOUND 2 (6TH STAGE) COMPRESSOR BLADES BROKEN AND SEIZED THE COMPRESSOR, ALSO REMOVED THE TURBINE ASSEMBLY DUE TO FOD.  WILL REPLACE THE COMPRESSOR ASSEMBLY AND TURBINE ASSEMBLY.
