DURING A PHASE 4 INSPECTION ON OUR KING AIR 200 N383JP, IT WAS DISCOVERED THAT THE MANUAL GEAR DOWN ACTUATION LEVER WOULD NOT OPERATE. UPON INSPECTION, IT WAS DETERMINED THAT THE ACTUATING LEVER CABLE GOING FROM THE ACTUATION LEVER TO THE LANDING GEAR GEARBOX WAS BROKEN APPROXIMATELY 18 INCHES FROM THE CONNECTION OF THE GEARBOX CLEVIS. THIS WOULD NOT ALLOW THE MANUAL GEAR DOWN PUMPING HANDLE TO ENGAGE AND ALLOW PUMPING OF THE LANDING GEAR DOWN IN CASE OF A LANDING GEAR MALFUNCTION. IT COULD NOT BE DETERMINED WHEN THE CABLE BROKE, OR THE ROOT CAUSE.

DURING FLIGHT, WHILE DECENDING TO FL220, THE CREW REPORTED THAT THEY COULD NO LONGERCONTRO THE AIRCRAFT CABIN PRESSURE SYSTEM. CREW DECLARED AN EMERGENCY & DECENDED TO FL10000, IN THAT TIME REGAINED CABIN PRESSURE CONTROL. NO PAX ABOARD. LANDED WITHOUT ISSUE. ROOT CAUSE NOT DETERMINED & UNDER INVESTIGATION. OPEN

WHEN PERFORMING AND AFTER PHASE INSPECTION CHECK FLIGHT, FOLLOWING TAKEOFF AND LANDING GEAR RETRACTION THE RED IN-TRANSIT LIGHT IN THE GEAR HANDLE WOULD REMAIN ILLUMINATED. THE AIRCRAFT RETURNED AND WAS PLACED ON JACKS. REPEATED LANDING GEAR CYCLES WERE NORMAL AND THE ISSUE COULD NOT BE GROUND DUPLICATED. ANOTHER CHECK FLIGHT WAS ACCOMPLISHED WITH THE RED LIGHT REMAINING AFTER RETRACTION. THE AIRCRAFT WAS AGAIN JACKED AND AGAIN, ALL CYCLES WERE NORMAL. UPLOCK SWITCH RIGGING WAS CHECKED AND FOUND NORMAL. AIRLOADS WERE SIMULATED ON THE GEAR AND ALL HANGAR RETRACTIONS WERE NORMAL. ANOTHER CHECK FLIGHT WAS ACCOMPLISHED WITH THE RED LIGHT REMAINING AFTER RETRACTION. THE AIRCRAFT WAS AGAIN JACKED AND THE GEAR CYCLED, AND OPERATION AND INDICATIONS WERE NORMAL. THE LANDING GEAR MOTOR WAS REPLACED AND THE LANDING GEAR WAS OPERATIONALLY CHECKED AND FOUND NORMAL. LANDING GEAR OPERATION AND INDICATIONS WERE NORMAL ON THE SUBSEQUENT CHECK FLIGHT, AND HAS BEEN NORMAL SINCE THAT REPLACEMENT.

LANDING GEAR WAS RETRACTED ON FINAL DEPARTURE FOR THE DAY RETURNING TO HOME BASE. ON LANDING GEAR RETRACTION, THE LANDING GEAR MOVEMENT STOPPED PRIOR TO COMPLETE RETRACTION AND THE CIRCUIT BREAKER FOR THE LANDING GEAR MOTOR TRIPPED. THE LANDING GEAR WAS MANUALLY EXTENDED PER CHECKLIST PROCEDURES AND PROPER DOWN AND LOCKED INDICATIONS WERE NOTED. THE AIRCRAFT LANDED WITHOUT INCIDENT. INSPECTION OF THE AIRCRAFT INDICATED THAT THE RIGHT INBOARD LANDING GEAR DOOR HAD CONTACTED THE MAIN LANDING GEAR DURING RETRACTION AND MINOR DEFORMATION AT THE DOOR CONTACT POINT WAS NOTED. THE FLIGHT CREW REPORTED THAT STRONG AND GUSTY WINDS WERE PREVAILING DURING THE SUBJECT TAKE-OFF. THE AIRCRAFT HAS BEEN REPOSITIONED TO A CERTIFIED REPAIR STATION UNDER SPECIAL FLIGHT PERMIT TO ACCOMPLISH FURTHER INSPECTION AND REPAIRS.

LEFT ENGINE OIL PRESSURE REPORTED AS READING HIGH - OFF OF THE SCALE. ALL OTHER ENGINE INDICATIONS WERE NORMAL. REMOVED DEFECTIVE TRANSMITTER AND INSTALLED SERVICEABLE PART AND INDICATIONS WERE OPERATIONALLY CHECKED AND FOUND NORMAL.

ON RE-POSITIONING FLIGHT FOR MAINTENANCE OF OTHER SYSTEM, AIRCRAFT WAS ON AUTO-PILOT AND ALTITUDE HOLD WAS SELECTED AND WAS INDICATED AS ENGAGED. THE AIRCRAFT DRIFTED OFF OF ALTITUDE HOLD SETTING TO A HIGHER ALTITUDE WHICH OCCURRED VERY GRADUALLY. UPON ARRIVAL, THE TROUBLESHOOTING OF SYSTEM IDENTIFIED THE AIR DATA COMPUTER AS THE ISSUE. INSTALLED AN OVERHAULED UNIT AND OPERATIONAL TESTED ALTITUDE HOLD SYSTEM AND FOUND PROPER OPERATION.
