What was found
(CAN) THE RT NR 3 LEADING EDGE (FIRST SECTION OUTBOARD OF THE LANDING LIGHTS) DEICE BOOT FAILED AFTER 1 DAY IN SERVICE. THIS IS A NEW STYLE DEICE BOOT FROM BFG, WITH A PEEL & STICK TYPE OF APPLICATION. THE FAILURE OCCURRED DUE TO THE STITCHING FAILING BETWEEN RIBS, CAUSING A LARGE CIRCULAR AREA OF SEPARATION WITHIN THE BOOT. DEICE SYSTEM PRESSURE WAS CHECKED WITHIN LIMITS. THE LEADING EDGE/BOOT ASSY WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
