Maintenance disclosures
DEPARTING PANC. WHILE PASSING THRU FL310 THE LH ENG FIRE LIGHT ILLUMINATED. PILOT DECLARED AN EMERGENCY AND RETURNED TO THE AIRPORT. NO INDICATIONS OUTSIDE OF THE WARNING LIGHT WERE PRESENT REGARDING ANY FIRE. LANDING WAS UNEVENTFUL AND AIRCRAFT RETURNED TO THE HANGAR. INITIAL INSPECTION POINTS TO A FALSE WARNING. INSPECTION OF THE INDIVIDUAL PHOTOVOLTAIC SENSORS AND WIRING SHOW NOT FAULTS. THIS IS A KNOWN ISSUE WITH THE PHOTOVOLTAIC SENSOR SYSTEM WHEN SUNLIGHT PASSES THROUGH THE EXHAUST GAPS IN THE COWLING AND HITS THE SENSORS AT JUST THE RIGHT ANGLE. WORKING ON CONFIRMING THIS NOW. NO EVIDENCE OF ANY HEAT OR FIRE IN THE COWLING.
RH MLG DID NOT SHOW DOWN AND LOCKED ON APPROACH. EMERGENCY GEAR EXTENSION WAS USED AND SAME RESULTS. RH GEAR DOWN AND LOCKED HAD NO GREEN AND THE RED HANDLE WAS STILL LIT UP. CREW DID A FLY BY OF THE TOWER AND CONFIRMED WHAT LOOKED LIKE GEAR DOWN. AIRCRAFT LANDED WITHOUT INCIDENT AND TAXIED UNDER ITS OWN POWER TO THE HANGAR. UPON STOPPING AT THE HANGAR, MAINT NOTICED THAT THE RH GEAR DRAG BRACES DID NOT APPEAR TO BE LOCKED. THE LOCK PIN HAD SPUN IN THE LOWER DRAG BRACE HOUSING AND WAS NOT ALLOWING THE LOCK PLATES TO ENGAGE. WE JACKED UP THE AIRCRAFT AND DISCOVERED THE SET SCREW FOR THE LOCK PIN WAS SPUN OUT. PER THE BEECH CMM FOR THE MAIN LANDING GEAR, WE RIGGED AND INSTALLED THE LOCK PIN AND THE SET SCREW WITH THREAD LOCKER. WHILE ON JACKS WE ALSO INSPECTED THE SET SCREW ON THE LH GEAR AND FOUND NO ISSUES. NUMEROUS GEAR SWINGS WERE PERFORMED WITH SATISFACTORY RESULTS. AIRCRAFT WAS RETURNED TO SERVICE.
UPON TURNING OFF THE FINAL TAXI WAY TO THE HANGAR IN ANC, CREW NOTED A STRONG ELECTRICAL SMOKE SMELL FOLLOWED BY SMOKE IN THE CABIN. UPON INSPECTION BY MAINTENANCE, NOTED THAT THE FLAP CONTROL BREAKER WAS POPPED. MAINT PUSHED THE BREAKER IN AND OPERATED THE FLAPS. AT THAT POINT, WE GOT A STRONG ELECTRICAL SMELL AND THE BREAKER POPPED AGAIN. TRACED THE ISSUE DOWN TO THE FLAP CONTROL RELAY. REMOVED AND REPLACED THE FLAP CONTROL RELAY WITH NEW AND OPERATIONAL CHECK IS GOOD. OPERATED NUMEROUS TIMES WITHOUT FAULT. AIRCRAFT WAS RETURNED TO SERVICE. PART NUMBER ON AND OFF SM50D7.

DURING CRUISE, PILOT NOTED THE RH CIRCUIT BREAKER PANEL BACKLIGHTING WAS FLASHING, FOLLOWED BY A MOMENTARY SMELL OF ELECTRICAL BURNING. THE BACKLIGHTING WAS TURNED OFF AND THE SMELL DISSIPATED. MAINTENANCE LOOKED AT THE ISSUE ON ARRIVAL TO ANC AND NOTED THAT THE POSITIVE TO NEGATIVE TERMINAL IN THE CONNECTION ON THE PANEL HAD SHORTED TOGETHER. EL PANEL WAS REMOVED AND PARTS ORDERED TO REMEDY. SYSTEM IS CURRENTLY DEACTIVATED AND ON AN MEL UNTIL PARTS ARRIVE TO CORRECT. A FOLLOW UP TO THIS SDR WILL BE SUBMITTED ONCE MEL IS CLEARED.
DURING FLIGHT, PILOT REPORTS THAT THERE WAS A MOMENTARY ELECTRICAL SMELL IN THE COCKPIT THAT DISSIPATED IN MOMENTS. THE SMELL DID NOT RETURN. UPON ARRIVAL, MAINTENANCE INSPECTED THE COCKPIT AREA AND FOUND NO ELECTRICAL SMELL. MAINTENANCE DID NOTICE THE RT CIRCUIT BREAKER PANEL BACKLIGHTING TO BE INOPERATIVE ON THE UPPER PORTION. THE PANEL WAS REMOVED AND THE LIGHTING ELEMENT PANEL WAS FOUND TO HAVE A SHORTED OUT SECTION BETWEEN THE POSITIVE AND NEGATIVE TERMINAL STRIPS. T THE AIRCRAFT WAS RETURNED TO SERVICE ON AN MEL(33-2) WHILE THE PANEL IS ON ROUTE FOR REPLACEMENT. NO FURTHER ISSUES WERE DISCOVERED.
DURING CRUISE FLIGHT, PILOT NOTED AN FAINT ELECTRICAL SMOKE ODOR. DETECTED IN THE CABIN AS WELL. TURNED BACK TO BASE. THE CREW IN THE BACK TRACED THE ODOR TO THE OVERHEAD PANEL THAT HOUSES THE AUTO TEMP SENSOR. THE PILOT THEN TURNED OFF THE AUTO TEMP MODE AND SELECTED MANUAL. IN JUST A FEW MINUTES THE SMOKE ODOR WAS GONE. ON LANDING, MAINTENANCE CHECKED OUT THE PLANE AND FOUND THE CIRCUIT BOARD AND FAN FOR THE TEMP SENSOR TO BE THE CAUSE OF THE ELECTRICAL SMOKE ODOR. PART WAS REMOVED AND AUTO TEMP SYSTEM WAS PUT ON AN MEL. OPERATIONAL CHECKS WERE GOOD AND AIRCRAFT WAS RETURNED SERVICE.
LOG PAGE WRITE UP IS AS FOLLOWS, RT ENG FIRE LIGHT ON APPROACH & LANDING, STAYED ON AFTER ENG SHUTDOWN. INSPECTED THE ENG FOR ANY SIGNS OF FIRE & FOUND NONE. THE FIRE WARNING LIGHT REMAINED LIT DURING INSPECTION. FOLLOWING THE TROUBLESHOOTING GUIDE IN THE AMM CH 26-10-01, WE FOUND THE LOWER FWD OPTICAL FIRE DETECTOR DID NOT HAVE THE PROPER GND SIGNAL. THE PART HAS BEEN ORDERED AT THIS POINT, PN 30-215-8 & SN 2365W. THE DEFECTIVE LOWER FWD OPTICAL FIRE DETECTOR UNIT WAS R & R WITH A NEW UNIT, PN 30-215-8 & SN 6811 ON AML 2124. NEW UNIT CORRECTED THE ISSUE & ACFT WAS RETURNED TO SERVICE.
FLAP WELL CLOSE OUT PANEL DELAMINATED AND BROKEN. 2 RIBS AND BRACKETS CRACKED. BRACKET STRINGER AND CLIPS CRACKED. 2 CRACKS IN T/E OF UPPER SKIN UNDER RAISBECK WING LOCKER ON LEFT WING. REPLACED DAMAGED SECTION OF SKIN. REPLACED FLAP WELL CLOSE OUT FAIRING AND DAMAGED PARTS.
MASTER WARNING AND LT ENGINE FIRE ANNUNCIATOR ILLUMINATED ON TAKEOFF ROLL. ABORTED TAKEOFF ROLL AND RETURNED TO HANGAR. TROUBLESHOOTING REVEALED FAULTY OPTICAL FIRE DETECTOR. REPLACED FAULTY DETECTOR, OPS CHECKS NORMAL.
ACFT WAS AT TOP OF DESCENT, NOTICED A BURNING ODOR AND A LIGHT SHEEN OF SMOKE IN THE CABIN. PERFORMED EMERGENCY PROTOCOL FOR CABIN SMOKE AND LANDED WITHOUT INCIDENT. FOUND NO ELECTRICAL ANOMOLIES WITH EITHER THE ACFT OR ANY OF THE MEDICAL EQUIPMENT ON BOARD. THERE WAS A PIECE OF TAPE FOUND IN THE DUCTING FOR THE HEATING SYS THAT SHOWED SIGNS OF SCORCHING. TAPE WAS REMOVED. ACFT WAS GROUND OPERATED FOR TWO HOURS, PERFORMING FUNCTION CHECKS ON ALL SYSTEMS WITH NO FURTHER OCCURENCE OF ANY SMOKE OR ODOR IN CABIN. ACFT WAS RELEASED TO SERVICE.
CLIMBING THROUGH ABOUT 23,000 FT, FLIGHT CREW HEARD A LOUD POP FOLLOWED IMMEDIATELY BY A LOSS OF CABIN PRESSURE. THE FLIGHT CREW IMMEDIATELY IMPLEMENTED THE EMERGENCY PROTOCOL FOR LOSS OF CABIN PRESSURE AN STARTED A DESCENT BACK TO DEPARTURE. THE MEDICAL CREW FOLLOWED THEIR TRAINING AND HELPED PASSENGERS WITH THEIR OXYGEN MASKS. OF THE FOUR LARGE PINS AND TWO UPPER LATCHES THAT SECURE THE DOOR, ONLY THE FORWARD UPPER LATCH LOST TENSION. THE DOOR STAYED CLOSED BUT PRESSURIZED AIR WAS LOST THROUGH A SMALL OPENING. THE AIRCRAFT LANDED WITHOUT INCIDENT. FAILED CLEVIS PIN WAS REPLACED IN DOOR LATCH LINKAGE.
SHORTLY AFTER TAKEOFF THERE WAS A FIRE WARNING LIGHT ON THE LT ENGINE. CREW ELECTED TO RETURN TO DEPARTURE. ALL GAUGES WERE IN THE GREEN AND THERE WAS NO VISIBLE INDICATIONS OF SMOKE OR FIRE COMING FROM THE ENGINE. CREW ELECTED NOT TO SHUT THE ENGINE DOWN. SEVERAL MINUTES LATER THE LIGHT WENT OUT AND ACFT LANDED. THE LT ENGINE WAS INSPECTED AND ALL COMPONENTS OF FIRE DETECTION SYS WERE TESTED. ENGINE RUNS WERE PERFORMED.
