## Discrepancy

(CAN) PILOT REPORTED RT DE-ICER BOOT WOULD NOT INFLATE WHEN REQUIRED TO REMOVE ICE BUILD-UP ON LEADING EDGE DURING FLIGHT.  MAINTENANCE FOUND BOOT INTERNALLY DELAMINATED BETWEEN CELLS AT W.S. 91.0.  THIS AREA IS WHERE THE WING FLEXES (SKINS JOINED AT THIS SPOT).  NEW BOOT INSTALLED.  SUBMITTER STATES THAT THIS IS A COMMON AREA OF FAILURE ON THIS MODEL OF AIRCRAFT.
