AIRCRAFT MED T/S DATED 24 NOV.2022 AND PERFORMED BY JET AVIATION (JBSL) TECHNICIAN FOUND AUX PUMP DEFECTIVE. DOOR WAS LOCKED MANUALLY ON 24 NOV.2022 WAITING FOR THE REPLACEMENT PUMP PROCUREMENT. ON 27 NO.2022, BEFORE THE PUMP REPLACEMENT, A CREW MEMBER (PILOT) ATTEMPTED TO OPEN THE DOOR AND, BECAUSE OF THE ABSENCE OF HYDRAULIC OPERABILITY, DOOR HAS OPENED RAPIDLY CAUSING INJURIES TO THE PILOT. NOTE: THE EVENT HAS BEEN NOTIFIED TO JET AVIATION ON 31 JAN.2023 BY THE AIRCRAFT'S OPERATOR - PEGASUS ELITE AVIATION. FOLLOWING THE NOTIFICATION, THE INTERNAL OCCURRENCE REPORT NO. 22715 HAS BEEN RAISED AND THE INTERNAL INVESTIGATION IS IN PROGRESS.

DURING FLIGHT FROM KVNY TO KJAC THE CAPTAIN NOTICED FUEL LEAKING FROM THE FILL CAP AREA OF THE LEFT HAND NACELLE FUEL TANK. THE AIRCRAFT WAS DIVERTED TO KLAS FOR INSPECTION. UPON INSPECTION BY A MAINTENANCE TECHNICIAN IT WAS DETERMINED THAT THE LEAK WAS DUE TO SEVERAL BOLTS THAT HAD BECOME LOOSE ON THE NACELLE BLADDER COVER PLATE. THE BOLTS WERE TORQUED TO SPECIFICATION IAW AMM 28-10-01. ENGINE GROUND RUN LEAK CHECK WAS PERFORMED AND THE AIRCRAFT WAS RETURNED TO SERVICE ON 03/29/2018.

AIRCRAFT WAS IN MAINTENANCE TO REPLACE FAULTY RIGHT HAND THRUST REVERSER ACTUATOR. AIRCRAFT WAS RETURNED TO SERVICE ON 03/28/2018. UPON ATTEMPTING TAKEOFF BOUND FOR KAPC, THE CREW REJECTED THE TAKEOFF DUE TO A RIGHT HAND THRUST REVERSER UNLOCK INDICATION. THE AIRCRAFT WAS RETURNED TO GULFSTREAM SERVICE CENTER AND THE LOWER THRUST STOW SWITCH WAS ADJUSTED. AIRCRAFT WAS RETURNED TO SERVICE ON 03/29/2018.

SMOKE PRESENT IN CABIN AFTER TAKEOFF. DURING POST FLIGHT INSPECTION, FOUND AUXILIARY CABIN HEATER SWITCH ON. PERFORMED CABIN HEAT OPERATIONAL CHECK IAW AMM21-42-00, NO DEFECTS NOTED. COULD NOT DUPLICATE SMOKE IN CABIN.

ACFT WAS ENROUTE. CREW DETECTED AN ODOR OF SOMETHING ELECTRICAL BURNING. ELECTED TO DIVERT THE FLIGHT WITHOUT INCIDENT. MX DETERMINED THAT THE NR 1 IRU FAILED AND WAS THE SOURCE OF THE ODOR. UNIT WAS REPLACED AND THE ACFT WAS RETURNED TO SERVICE.

AT FL 410 ECS INLET OVERHEAT LIGHT ILLUMINATED, CREW PUT MAIN AIR VALVES BOTH ON LB AND STARTED A DESCENT TO FL 350. APPROX 1 MINUTE AFTER START OF DESCENT THE CABIN BEGAN A RAPID CLIMB IN EXCESS OF 10,000 FT. CREW BEGAN AN EMERGENCY DESCENT AND DECLARED AN EMERGENCY TO ATC. ACFT DIVERTED FROM ROUTE TO ALTERNATE, LANDING WAS UNEVENTFUL WITH NO INJURIES TO PAX OR CREW. INSP OF ACFT SHOWED NO ISSUES AND ACFT IS BEING FERRIED UNPRESSURIZED FOR FURTHER INSP AT THIS TIME. (K)

ACFT WAS ON A REPOSITIONING FLIGHT. APPROX 1 HR INTO FLIGHT, ATC CLEARED ACFT FROM FL390 TO FL240 AND A DESCENT OF 3000 FPM WAS STARTED. AFTER A FEW MINUTES INTO DESCENT BOTH PFD AIRSPEED TAPES FAILED. CREW NOTED POSSIBLE PITOT TUBE ICING AND TOOK EMERGENCY ACTION TO INCLUDE DECLARING AN EMERGENCY WITH CTR AT FL220 ALL PFD INDICATION RE-APPEARED ON BOTH PFD`S AND ALL WARNING FLAGS DISAPPEARED.

ON TEST FLIGHT, FOR RT WING OVER PRESSURE LT ON, AT FL230 EXPERIENCED A LT BLEED DUCT FAIL LIGHT. CREW PERFORMED EMERGENCY PROCEDURE IAW CHECKLIST. AT THAT POINT, SMELLED SMOKE IN CABIN. CREW DECLARED EMERGENCY AND DESCENDED BACK TO DEPARTURE WITH AN UNEVENTFUL LANDING. MFG WAS CONTRACTED BY OPERATOR TO PERFORM INSP AND MX FOUND LT BLEED DUCT COUPLING BLEED LEAK NOTED THAT WHEN EMERGENCY BLEED IS SELECTED BY FLIGHT CREW. RAW BLEED AIR IS PUMPED INTO CABIN CAUSING DUCT OUTLETS TO OVERHEAT AND GET SMOKE IN CABIN. MFG IS CONDUCTING FURTHER INSP AT THIS TIME. (K)

AFTER DEPARTED, GOING THROUGH APPROX 800 FT AGL THE F/O NOTED THAT THE RUDDER HAD LOCKED UP IN THE NEUTRAL POSITION. THE OAT AT THE TIME WAS +9C. ACFT CONTINUED TO CLIMB AND CAPTAIN INFORMED ATC THAT WOULD BE RETURNING TO DEPARTURE. ACFT WAS ABOVE MAX LANDING WEIGHT SO FLIGHT CREW REQUESTED A DELAY IN LANDING UNTIL ACFT BURNED OFF FUEL BELOW MAX LANDING WEIGHT. FLIGHT CREW DID NO DECLARE AN EMERGENCY AND NO PASSENGERS WERE ON ACFT. THE WINDS WERE CALM AND THE APPROACH AND LANDING WAS WITHOUT INCIDENT. ONCE ON GROUND THE RUDDER RETURNED TO NORMAL WITHOUT ANY INPUT FROM FLIGHT CREW. ANTI-ICE SYSTEMS WERE IN FORMAL OPERATION DURING FLIGHT, YAW DAMP AND AUTO-PILOT WERE NEVER ENGAGED DURING FLIGHT.

CREW NOTED ON SELECTING GEAR DOWN THAT THE NR 1 GEAR DOWN LIGHT WAS NOT ILLUMINATED. CREW ELECTED TO DO A FLY BY TO VISUALLY VERIFY GEAR DOWN AND LOCKED. GEAR WAS VERIFIED BY TOWER, AC MADE AN UNEVENTFUL LANDING. CONTRACT FOR INSP AND MAINT, ON INSP FOUND THAT NR 2 OB T/R STOW SWITCH WAS FAULTY, SWITCH WAS REPLACED, OPERATIONALLY CHECKED. FOUND THAT NR 1 MAIN GEAR DOWN LIGHT WAS BURNED OUT. LAMP WAS REPLACED WITH A NEW LAMP (PN AS327) AND OPERATIONALLY CHECKED. AC WAS RELEASED FOR MAINT/REPOSITION TEST FLIGHT. (K)

AC DEPARTED AND SHORTLY AFTER DEPARTURE, SMOKE WAS NOTED IN CABIN WITH BAGGAGE SMOKE DETECTOR INDICATING SMOKE IN BAGGAGE COMPARTMENT. FLIGHT CREW DECLARED AN EMERGENCY AND RETURNED TO DEPARTURE, APPROACH AND LANDING WERE UNEVENTFUL WITH NO OTHER INDICATION OF FIRE. UPON LANDING, FIRE DEPT CHECKED FOR HEAT SOURCES WITH NONE FOUND. CONTRACTED FOR INSPECTION AND MAINT, FOUND THAT THE RT (NR 2) ENGINE WAS MAKING SMOKE THROUGH THE ENGINE BLEEDS AND INJECTING SMOKE INTO THE CABIN. THIS ENGINE WAS A LOANER ENGINE FROM MFG AND AS SUCH MFG WAS CONTACTED. SERV REP WAS ON SITE AND DETERMINED THAT OIL WAS LEAKING INTERNALY AND ENGINE IS BEING REMOVED AND SERVICEABLE ENGINE INSTALLED. NOT KNOW AT THIS TIME WHAT PART FAILED INTERNALLY IN ENGINE. (K)

IN CRUISE FLIGHT AT FL380, CREW FELT A VIBRATION, IT CONTINUED TO GET STRONGER. CREW REQUESTED ATC TO LAND AT NEAREST SUITABLE AIRPORT BUT DID NOT DECLARE AN EMERGENCY.
