Part: DISPLAY — FROZEN (ZONE 200) · airframe 7,956 hrs · 8,472 cycles
EIS GAUGES: TRQ, ITT, NG, FUEL QTY AND FL/H USED ALL FROZE. THIS PROBLEM WAS INTERMITTENT AT FIRST, THEN THE LAST 15 MINUTES, THE GAUGES FROZE.
Part: CONNECTOR — WRONG PART (AUTOPILOT) · airframe 3,192 hrs
AUTOPILOT UNCOMMANDED ROLL OSCILLATION EXCEEDING BANK LIMITS. FOUND OPEN ROLL LOW SIGNAL BETWEEN NR 1 AHRS AND AUTOPILOT COMPUTER. FURTHER INSPECTION REVEALED INCORRECT SOCKET INSTALLED IN P909, PIN 77. INSIDE DIAMETER WAS TOO LARGE, .063 VS. REQUIRED .040, RESULTING IN POOR, INTERMITTENT CONNECTION. INSTALLING CORRECT SIZED SOCKET CLEARED THE DISCREPANCY.
Part: BOOT — FAILED (ZONE 600)
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.
