AFTER TAKE OFF, DURING NORMAL CLIMB, CLIMB CHECKLIST ACCOMPLISHED, NR 1 ENGINE ITT WAS NOTED TO BE HIGH AT 840°- OIL PSI 125 - OIL TEMP 110°. POWER WAS REDUCED ON AFFECTED ENGINE, BUT CONDITION PERSISTED DICTATING A PRECAUTIONARY NR 1 ENGINE SHUTDOWN AND RETURN TO POINT OF DEPARTURE. A SINGLE ENGINE RETURN, APPROACH AND LANDING WAS ACCOMPLISHED.

DURING FLIGHT, THE AIRCRAFT WAS LEVEL AT 8000 FEET WITH CRUISE CHECKS COMPLETED AND THE SCHEDULED POWER WAS SET. NO ABNORMAL INDICATIONS WERE OBSERVED BY THE CREW DURING CRUISE AND NO MAJOR POWER ADJUSTMENTS WERE MADE ENROUTE. WHILE STILL AT CRUISE POWER JUST PRIOR TO INITIATING THE DECENT, THE FO BRIEFLY NOTICED THE RIGHT GENERATOR LIGHT APPEARING FOR FEW SECONDS ON THE CWP FOLLOWED BY COMPLETE FAILURE OF THE RIGHT ENGINE. A VISUAL CHECK OF THE RIGHT ENGINE WAS MADE CONFIRMING THAT THERE WAS NO FLAME PRESENT AND THE AUTOFEATHER MECHANISM WAS ENGAGED. THE CREW PERFORMED THE VITAL AND QRH ACTIONS TO SECURE ENGINE, AND ATLANTA CENTER WAS NOTIFIED OF THE FAILED ENGINE. AN EMERGENCY WAS DECLARED. A ONE ENGINE APPROACH AND LANDING WAS COMPLETED WITH NO FURTHER INCIDENT.

FIRST OFFICER NOTICED AFT CARGO COMPARTMENT SMOKE LIGHT ILLUMINATE IN FLIGHT. PER RH CAPTAIN DISCHARGED FIRE EXTINGUISHERS INTO AFT BAGGAGE COMPARTMENT AND DECLARED AN EMERGENCY. A SUCCESSFUL LANDING WAS ACCOMPLISHED. INSPECTED AND DETERMINED NO ACTUAL FIRE OR SMOKE WAS PRESENT.

ON APPROACH, FOLLOWING APPROACH CHECKLIST AND SELECTING GEAR DOWN, F/O NOTED THE NOSE GEAR LIGHT ILLUMINATED RED, WHILE THE GEAR LEFT AND GEAR RIGHT WERE GREEN. AIRCREW REQUESTED DELAYED VECTORS TO ACCOMPLISH REQUIRED CHECKLIST. AFTER PERFORMING APPROPRIATE ACTIONS AND GEAR NOT INDICATING GREEN OR DOWN AND LOCKED, AN EMERGENCY WAS DECLARED. ATC AUTHORIZED A LOW PASS ON THE RUNWAY, AND EMERGENCY PERSONNEL VERIFIED GEAR WAS DOWN. ACFT RE-ENTERED THE TRAFFIC PATTERN AND CONTINUED TO MAKE A SAFE LANDING WITHOUT INCIDENT. LOCAL MAINTENANCE PINNED THE LANDING GEAR AND PLACED THE LANDING GEAR ON MEL AND DOCUMENTED THE MAINTENANCE LOGS APPROPRIATELY. ACFT IS CURRENTLY UNDERGOING INSPECTION TO DETERMINE CAUSE OF ERRONEOUS INDICATION.

CREW EXPERIENCED NR 1 ENGINE FLUCTUATIONS DURING CLIMB. NECESSARY CLIMB POWER SETTINGS DID NOT AFFECT THE INDICATIONS. AIRCREW DECIDED TO RETURN TO BLOCK IN ORDER TO BE SAFE AND HAVE MAINTENANCE LOOK INTO THE ISSUE. MAINTENANCE LOOKED INTO ISSUE, CHANGED OVERSPEED GOVERNOR AND PROP GOVERNOR. NO FURTHER OCCURRENCES.

AFTER BEING CLEARED FOR TAKEOFF & APPLYING TAKEOFF POWER, FIRST OFFICER NOTICED, AUTO FEATHER, LIGHT FAILED TO ILLUMINATE & CALLED ABORT. ACFT PULLED OFF ACTIVE RUNWAY & PARKED ON TAXIWAY WHERE IT WAS FOUND THAT AUTO FEATHER CIRCUIT BREAKER WAS TRIPPED. CIRCUIT BREAKER WAS RESET & ACFT CONTINUED ITS SCHEDULED FLIGHT WITHOUT INCIDENT AS NORMAL.

DURING A 100 HOUR INSPECTION OF THE FUEL CAP AND FUEL CELL AREA A PIECE OF PLASTIC WAS FOUND LAYING IN THE FUEL FILLING AREA. AFTER INSPECTING THE FUEL CAP THE PIECE OF PLASTIC THAT WAS FOUND WAS CONFIRMED TO COME FROM THE PLASTIC PART OF THE FUEL CAP.

UPON TAKEOFF ROLL & ACCELERATION, AT APPROX 89 KNOTS, THE FIRST OFFICER NOTICED HIS AIRSPEED INDICATOR WAS INDICATING 0. PIC RETARDED POWER LEVERS TO IDLE & ABORTED THE TAKEOFF. ACFT RETURNED TO BLOCK. UPON INSPECTION, TECHNICIAN CLEARED PITOT TUBE OF A NOTICEABLE INSECT LODGED IN THE TUBE OPENING. HIGH SPEED TAXI WAS PERFORMED WITH NO AIRSPEED INDICATION RECOVERED. DISCONNECTED AIR SPEED INDICATOR & UTILIZING COMPRESSED AIR BLEW OUT DEBRIS FROM LINES & MANUALLY CLEANED OUT PITOT TUBE ENTRANCE. A PITOT & STATIC SYS LEAK CHECK WAS PERFORMED.
