## Discrepancy

NOTICED CRACKS BETWEEN WINDOW LATCH BRACKET HOLES DURING A PHASE 1 CHECK.  REMOVED BOTH STORM WINDOWS AND FOUND INNER PLY CRACKS IN BETWEEN ALL 5 DRILLED MOUNTING HOLES IN ADDITION TO THE LATCH BRACKET CRACKS.  THE WINDOW ALSO EXHIBITS STRESS CRACKS IN THE MILLED RADIUS AROUND THE WINDOW PERIMETER.  SUGGEST A CYCLE LIMIT OR DETAILED INSPECTION.  MOST CRACKS ARE NOT VISIBLE UNTIL SEPARATING THE WINDOW FROM ITS HINGE MOUNT.   6853 CYCLES/22 YEARS
