## Discrepancy

ENGINE DISASSEMBLED DUE TO BIRD STRIKE.  FOUND NR 2 CYLINDER BARREL CRACKED AT JOINT OF BARREL AND HEAD.  CRACK IS APPROXIMATELY 2 INCHES LONG, LOCATED RADIALLY AROUND BORE.  CYLINDER SHOWS EVIDENCE OF LEAKAGE EXTERNALLY IMMEDIATELY BELOW FINNED AREA OF HEAD.  SUGGEST CHECKING CYLINDERS FOR LEAKAGE AT INTERSECTION OF BARREL AND HEAD AT  REGULAR INSPECTION.
