## Discrepancy

AFTER INSTALLATION OF A FULL SET OF PNEUMATIC DEICE BOOTS ON THE ACFT, PROCEEDED TO PERFORM THE OPS TEST OF THE PNEUMATICE DEICE BOOT SYSTEM.  AT WHICH TIME, IN THE APPROPRIATE TIME IN THE SEQUENCE OF INFLATION, THE RT WING INBD BOOT HAD INFLATED PROPERLY, BUT BEFORE THE SEQUENCE WAS ENDED AND IT WAS DEFLATING, THE BOTTOM, INBD, AFT SECTION OF THE BOOT RELIEVED THE AIR PRESSURE AT A HIGH RATE.  HALTED THE OPS CYCLE AT THAT TIME.  UPON INSPECTION OF THE BOOT, FOUND THE "WING SIDE OF THE BOOT HAD ADHERED TO THE WING PROPERLY AND WAS NOT AT FAULT, BUT THE "STITCHING" THAT FORMS THE CHANNELS IN THE BOOT, HAD LET GO AND CONSEQUENTLY SPLIT THE SEAM ON THE AFT SIDE OF THE BOOT, SEPARATING THE LAYERS OF THE BOOT, CAUSING IT TO DUMP AIR OVERBOARD.
