## Discrepancy

APPROXIMATELY AFTER 1 HOUR INTO FLIGHT THE RT WINDSHIELD CRACKED.  FLIGHT MANUAL PROCEDURES FOR THIS TYPE OF OCCURRENCE WERE FOLLOWED & AN UNEVENTFUL LANDING WAS MADE.  AFTER LANDING INSPECTED THE WINDSHIELD & DETERMINED THE CRACKING HAD OCCURRED IN THE OUTER PANE ONLY.  THE WINDSHIELD WAS SUBSEQUENTLY REPLACED WITH A FACTORY NEW WINDSHIELD & THE ACFT WAS RETURNED BACK TO SERVICE.  THE CAUSE OF THE CRACKING IS TO BE DETERMINED BY THE INSURANCE COMPANY AS IT IS SUSPECTED A POSSIBLE EARLIER LIGHTNING STRIKE MAY HAVE BEEN A DETERMINING FACTOR IN THE FAILURE. IF LIGHTENING WAS NOT A FACTOR IT IS BELIEVED CRACKING MAY HAVE BEEN DUE TO A FAILURE OF THE HEATING ELEMENT AT THE LOWER BUSS BAR.
