## Discrepancy

RT INTAKE HEAT FAIL LIGHT ILLUMINATED THEN CYCLED ON AND OFF.  SHORTLY AFTER FAIL LIGHT FOR INTAKE HEAT, CREW SMELLED CHEMICAL SMELL IN FLIGHT DECK.  EMERGENCY LANDING IN BJI PER DISPATCH.  CONTRACT MAINTENANCE CALLED OUT.  FOUND INTAKE HEAT MAT INSIDE RT ENGINE BURNT.  SMALL HOLE 1 1/2 INCHES LONG BY 1/2 INCH WIDE.  THIS EXPLAINS THE CHEMICAL SMELL IN THE FLIGHT DECK.  REPLACED THE LOWER DUCT AND THE SHOE BOX.  PN ON/OFF NH246B165-01, S/N ON L180892 SN OFF L2907-84. OPS CHECK GOOD.
