BEGAN TAKE-OFF ROLL AND WITHIN THE FIRST 500 FT SIC NOTED AN INVALID AIRSPEED INDICATION. CREW ABORTED TAKE-OFF @ ABOUT 70 KTS AND RETURNRD TO RAMP.UPON INVESTIGATION IT WAS FOUND THAT SOME DEBRIS WAS CAUSING THE BLOCKAGE THAT WAS FROM THE WORN PITOT COVERS.TO CORRECT ISSUE NEW COVERS WERE INSTALLED.

ON CLIMB OUT , DCU A , DCU B , AP PITCH CONTROL FAIL , IFIS MISCOMPARE AND AP FAIL . UPON ARRIVAL OF MX NO FAULT WAS FOUND . GAINED ACCESS TO THE FAULT HISTORY AND VERIFIED THERE WAS A DCU CHANNEL B FAULT IN THE AIR WITH A FDR-1 MODULES BUS INOP MESSAGE PRESENT DURING FAULT WHICH TRIGGERED AN A/P PITCH TRIM FAIL MESSAGE AND PRESSURIZATION 2 FAIL MESSAGE . REMOVED CARD FROM ARES BOX AND DOWNLOADED FILE FOR 8/03/23 TO FORWARD TO TEAM CJ FOR EVALUATION. POWERED AIRCRAFT AGAIN TO VERIFY NO FAULTS ARE PRESENT AT THIS TIME.

GEN FAIL CAS MESSAGE, RH GEN OFF LIGHT ILLUMINATED. BEGAN TROUBLE SHOOTING BY SWAPPING OUT PCB1 AND PCB3 ON THE RIGHT AFT PDP. THESE ARE THE GCU'S FOR THE RIGHT ENGINE AND THE APU(24-60-03). ATTEMPTED TO RUN ENGINES, RIGHT BATTERY WOULD NOT COME ONLINE. BEGAN TROUBLE SHOOTING THAT ISSUE AT THE SWITCH INSIDE THE COCKPIT(24-31-00). VERIFIED BATTERIES HAD GOOD VOLTAGE, SWAPPED BATTERIES, NO CHANGE TO THE RH BATTERY COMING ON. VERIFIED ALL PCB BOARDS WERE INSERTED PROPERLY INCLUDING ONES NOT TAMPERED WITH AND RH BATTERY CAME BACK ON. MOVED RH GEN TO LH ENGINE AND VICE VERSA TO CONFIRM RH GEN WAS NO LONGER OPERATING. RH GEN ON THE LEFT SIDE FAILED AS WELL AS LH GEN ON THE RIGHT SIDE. DOUBLE GEN FAIL(24-30-01). RECEIVED NEW GEN INSTALLED ON THE RH, STILL FAILED. SWAPPED GENERATORS AGAIN STILL RH GEN ON LEFT SIDE CAME ONLINE BUT LH GEN ON RIGHT SIDE DID NOT COME ON DURING ENGINE RUNS. PLACED IN ORIGINAL POSITION RH GEN STILL FAILED(24-30-01). ALSO SWAPPED AROUND PCB BOARDS FROM LEFT AND RIGHT PDP'S, THIS DID NOT REMEDY OUR PROBLEM. PCBS WERE PLACED IN ORIGINAL COMPARTMENTS. PROCEEDED TO TROUBLESHOOT WIRES CORRESPONDING FROM THE RH GEN TO THE RIGHT AFT PDP, FOUND NO SHORTS OR LACK OF CONTINUITY IN ANY OF RING OUTS(24-30-00). TESTED VOLTAGE AT THE GEN AND AT THE POTENTIOMETER THE READING WAS LESS THAN 1 VOLT AT BOTH LOCATIONS AND WE WERE NOT ABLE TO INCREASE VOLTAGE AT THE POTENTIOMETER WITH RH ENGINE RUNNING(24-60-03). S/N OFF S4440 TROUBLESHOOTING DONE IAW LEARJET 45 AMM AND AWM.

MAINTAINED 4000 FT FOR APPROXIMATELY 45 MINUTES TO BURN FUEL FOR A LANDING CONFIGURATION.LANDED AND RETURNED TO RAMP .

DURING CLIMB, THE LT ITT JUMPED INTO THE RED ON THE INDICATOR. PILOT IMMEDIATELY REDUCED POWER AND DIVERTED. ON INITIAL EXAMINATION FOUND PAINT ON LT STUB WING AND SURROUNDING AREA INDICATING HEAT DAMAGE. ALSO OBSERVED PYLON SKINS WARPED AND RIPPLED.

PRECOOLER FAILED CAUSING BLEED LEAK THAT CAUSED ITT TO EXCEED LIMITS ON TAKEOFF ROLL. DURING THE ROLL THE CO-PILOT NOTED SMOKE IN COCKPIT AND CALLED FOR ABORT. ABORT WAS SUCCESSFUL. ACFT TAXIED BACK FOR EVALUATION AND REPAIRS.

AFTER A NORMAL TAKEOFF THE PILOT SELECTED GEAR UP AND HEARD A BANG WHEN THE GEAR RETRACTED. THE GEAR WAS LOWERED AND 2 FLYBYS WERE DONE TO VERIFY GEAR POSITION. IT WAS REPORTED THAT THE NOSE TIRE WAS AT ABOUT A 30 DEGREE LT FACING POSITION. AFTER FOLLOWING THE PROCEDURES IN THE FLIGHT MANUAL, THE PILOT MADE A SUCCESSFUL LANDING WITHOUT INCIDENT. INITIAL REVIEW OF THE ACFT, NO DAMAGE WAS FOUND ON ANY PART OF THE ACFT, AND NO INJURIES WERE REPORTED BY CREW OR PASSENGERS. AT THIS POINT IT LOOKS LIKE THE NOSE STRUT LOST PRESSURE SOMETIME.

FOUND EMERGENCY LIGHTS ON BUT SWITCHES WERE OFF. PULLED CIRCUIT BREAKERS, LIGHT WENT OUT. SEVERAL HOURS LATER, ON PREFLIGHT, DISCOVERED BLACK SOOT COMING OUT OF ENGINE COWLING. DISCOVER WHAT APPEARS TO BE AN ELECTRICAL FIRE HAD OCCURRED. APPEARS THAT A RESISTOR SHORTED OUT AGAINST THE BATTERY RELAY, AND MELTED PLASTIC COVER AND CREATED A BURNED ASH OVER THE RELAY BOX AND SURROUNDING AREAS. NO STRUCTURAL DAMAGE TO ENGINE MOUNT OR FIREWALL/PRESSURE BULKHEAD HAS BEEN NOTED.

LOWERED LANDING GEAR AND RECEIVED A NOSE WHEEL STEERING FAIL MESSAGE. PERFORMED A GO AROUND AND WENT OVER CHECKLIST. LANDED, ENGAGED NOSE WHEEL STEERING, CAUTION LIGHT WENT OUT AND HAD NOSE WHEEL STEERING. TAXIED AIRCRAFT TO FBO WITHOUT INCIDENT. FOUND DOWNLOCK SWITCH FAILED.

CRUISING AT FL400 FOR APPROX 1 HR 45 MIN WITH NO INDICATION AT ANYTIME, SUSPECTED LIGHT EMERGENCY BLEED AIR ACTIVATED, SUSPECTED LIGHT DUE TO THE INCREASE IN THE CABIN TEMP. WITH A DISTINCT HOT ODOR FILLING UP IN THE ACFT CABIN, THE FLIGHT CREW DESCENDED TO FL100, BEGAN CHECK LIST PROCEDURES TO CYCLE THE PRESSURIZATION SWITCH TO MANUAL MODE AND THEN BACK TO AUTO. BLEED VALVE APPEARED TO RESET, CABIN TEMP STABILIZED. FLIGHT CREW SLOWING ASCENDED TO FL240, CABIN TEMP WAS STABILE. FLIGHT CREW DECIDED TO ERROR ON THE SIDE OF CAUTION AND LAND TO HAVE FURTHER MX PERFORMED ON THE ACFT. THE TECH CONDUCTED A GROUND ENGINE RUN AND PRESSURIZED THE ACFT. PERFORMED AN EMERGENCY PRESSURIZATION CHECK OF THE SYS, SEVERAL CYCLES THROUGH. NO FAULTS FOUND, SYS FUNCTION NORMAL. FLIGHT CREW THEN CONTINUED ON TO THEIR FINAL DESTINATION WITH NO FAULT NOTED.
