## Discrepancy

THE FLIGHT CREW REPORTED THAT THE ENTIRE OUTER GLASS PLY OF THE LEFT WINDSHIELD SHATTERED IN FLIGHT AT FLIGHT LEVEL 43,000 FEET, MACH 0.76, SAT -59 C, NEGATIVE ICING, CABIN 9.1 PSID, CABIN ALTITUDE 6,600 FEET. THE CREW ELECTED TO LAND FOR EVALUATIONS AT KPDK. THE LANDING WAS UNEVENTFUL. THE MAINTENANCE TEAM WAS UNABLE TO DEFINE A CAUSE FOR THE WINDSHIELDS FAIL, NO OBVIOUS DEFECTS WERE FOUND. THE REPLACEMENT WILL BE DELAYED BY MATERIALS SHORTAGE AND THE AVAILABILITY OF A NEW WINDSHIELD. NO PART OR SERIAL NUMBER AVAILABLE FROM THE FAILED WINDOW AT THIS TIME.
