Maintenance disclosures
WHILE PERFORMING AN INSPECTION ON THE R/H CIRCUIT BREAKER PANEL THE WIRE TERMINALS WERE FOUND BROKEN ON TWO OF THE THREE 75A FEEDER CIRCUIT BREAKERS AND THE THIRD TERMINAL WAS CRACKED AND ABOUT READY TO BREAK. THESE WIRES FEED POWER TO THE R/H CIRCUIT BREAKER PANEL FROM THE AFT POWER JUNCTION BOX. HAD THE LAST TERMINAL BROKEN ALL POWER FROM THE AFT POWER JUNCTION BOX TO THAT BREAKER PANEL WOULD HAVE BEEN LOST AND THE PANEL WOULD BE THEN BE FED SOLELY FROM THE 35A CROSS-FEED BREAKER WITH NO INDICATION TO THE FLIGHT CREW. THE CAUSE OF THE BREAKAGE WAS DUE TO THE WIRE RUNS BEING TOO SHORT CAUSING A STRAIN ON THE WIRES AND TERMINALS. A GENERAL VISUAL INSPECTION IS NOT SUFFICIENT TO LOCATE THIS ISSUE AS EACH WIRE ALSO HAS AN INSULATING BOOT ON EACH WIRE COVERING THE TRERMINAL GIVING A VISUAL EFFECT THAT THE WIRING IS INTACT. SLACK WAS OBTAINED FROM THE WIRE BUNDLE DOWNSTREAM FROM THE BREAKER PANEL AND THE WIRE TERMINALS WERE REPLACED AND REATTACHED TO THE CIRCUIT BREAKERS. OPPOSITE PANEL WAS INSPECTED WITH NO ISSUES FOUND.
UPON DECENT THE LT PITOT HEAT ANNUNCIATOR ILLUMINATED. THE AIRCRAFT MADE AN UNEVENTFUL LANDING AT DESTINATION. THE HEAT WAS DEFERRED PER MEL BUT DUE TO RESTRICTIONS OF THE MEL THE AIRCRAFT COULD NOT COMPLETE THE REMAINDER OF THE SCHEDULED MISSION AND RETURNED TO BASE. THE AIRCRAFT WAS THEN TURNED OVER TO MAINTENANCE. INVESTIGATION REVEALED THAT THE LT PITOT TUBE WAS DEFECTIVE AND SUBSEQUENTLY REPLACED AND AIRCRAFT RETURNED TO SERVICE AFTER SUCCESSFUL OPERATIONAL AND LEAK CHECKS.
AFTER LANDING THE AIRCRAFT WAS TAXIED TO THE RAMP AND SHUT DOWN. WHEN THE CABIN DOOR WAS OPENED STRONG WIND CAUGHT AND FLUNG IT OPEN HARD RESULTING IN THE LOWER DOOR HINGE BEING BROKEN. THE AIRCRAFT WAS TURNED OVER TO MAINTENANCE WHERE SOME MINOR MODIFICATION WAS MADE IN PREPARATION FOR A FERRY FLIGHT BACK TO HOME BASE WHICH WAS MADE SUCCESSFULLY. A NEW HINGE WAS PROCURED AND INSTALLED. ALL CREW TO BE REMINDED OF SUCH INCIDENTS THAT CAN BE AVOIDED BY BEING AWARE OF OUTSIDE GROUND CONDITIONS AND PROPERLY POSITIONING OF AIRCRAFT ACCORDINGLY.
DURING CLIMB OUT THE RT GEN ANNUNCIATOR ILLUMINATED & NO OUTPUT WAS OBSERVED ON THE AMMETER. CHECKLIST PROCEDURES WERE FOLLOWED & THE ACFT MADE AN UNEVENTFUL LANDING BACK AT DEPARTURE AIRPORT & THE ACFT WAS TURNED OVER TO MX. INITIAL INVESTIGATION NOTED THAT THE BITE INDICATOR ON THE RT GCU WAS INDICATING A GND FAULT & AN ABNORMAL AMOUNT OF STAINING WAS NOTED COMING FROM THE GEN EXHAUST ON THE RT ENG COWL. INSPECTION OF THE STARTER & GEN WHILE STILL INSTALLED REVEALED PITTING & SCORING ON THE COMMUTER. AFTER REMOVAL OF THE STARTER & GEN IT WAS DISCOVERED THAT THE FWD BEARING HAD FAILED WITH THE ABNORMAL PLAY ALLOWING THE COOLING FAN TO STRIKE THE HOUSING & THE RESULTANT DEBRIS GETTING INTO THE BRUSH & COMMUTER AREA, SHORTING, THUS CAUSING THE GND FAULT. THE STARTER & GEN WAS REPLACED WITH AN OVERHAULED UNIT & THE GCU WAS RESET. GND OPERATIONAL & PARALLELING CHECKS WERE GOOD. THE FAILED UNIT HAD 364 HOURS TO GO UNTIL REQUIRED OVERHAUL, 1,000HR INTERVAL.
