The twin engine airplane crashed into the sea some 1,5 km off the beach of Punta Carola, San Cristóbal Island, Galapagos. The airplane sank while all nine occupants were rescued. It appears that the airplane was en route to Puerto Villamil Airport, Isabela Island, when the accident occurred.

Coded 37 Red and operated by the Russian Aerospace Forces (VKS-Vozdushno-kosmicheskiye sily Rossii), the airplane was engaged in a survey mission of the south Crimea area when it was apparently shot down by Ukrainian Forces and crashed into the Azov Sea off the city of Kyrylivka. It is believed that all 11 crew members have been killed.

The airplane departed Canouan Airport at 1427LT on a local flight, carrying apparently three passengers and one pilot. About six minutes after takeoff, the airplane disappeared from radar screens and crashed into the sea two minutes later, at 1435LT. It is unclear if the wreckage was found. The airplane's operations were apparently monitored by the Drug Enforcement Administration (DEA) for some time and it is believed that the pilot may have switched off the transponder after takeoff. Illegal operation suspected.

On the morning of 10 November 2023, a Cessna 421C, registered VH-VPY, departed the Sunshine Coast Airport, Queensland for a transpacific international ferry flight to Oakland, California in the United States. Two pilots were on board to conduct the flight, where the first leg was planned to stop at Pago Pago, American Samoa. The aircraft was configured with additional ferry fuel tanks to ensure sufficient fuel was available between the stops for the extended journey across the open ocean. Approximately 50 minutes after departure, the left engine failed and the pilots initiated a return to the Sunshine Coast. During the return leg the pilots identified that the aircraft was unable to maintain altitude and calculations based on the descent rate indicated they would be unable to reach the Sunshine Coast. The pilots notified air traffic control of their intention to ditch, who immediately engaged the national search and rescue service provider. After considering the configuration of the aircraft, the pilots elected not to follow the aircraft manufacturer’s guidance on ditching. They configured the aircraft to avoid a nose down attitude on touchdown and allowed their airspeed to slow before the aircraft contacted the water. Both occupants were uninjured and exited through the rear door. After deploying the emergency life raft, both pilots were retrieved by a rescue helicopter 32 minutes after ditching. The aircraft sank and was not recovered.

On 19th August 2023 at approximately 12:25 pm local (1625 UTC), a Cessna 402B aircraft which was last registered in The Bahamas until 17th July 2022 as C6-SPK (serial number 402B-1054), departed from the Fort Lauderdale International Airport (KFLL), Fort Lauderdale, FL, USA with one (1) person on board enroute to the North Eleuthera International Airport (MYEH), Eleuthera, Bahamas. The aircraft was expected to return to KFLL shortly after 2:00 pm later that afternoon, however, it never arrived at its intended destination. It was reported that at approximately 12:58 pm (1658 UTC), KFLL air traffic control observed the aircraft in a rapid descent from an altitude of approximately 8,400 feet mean sea level (MSL) to about 4,500 feet MSL, while at coordinates 25.84N 78.90W, approximately some 70 nautical miles south east of KFLL, or approximately 18 nautical miles north east of Bimini, Bahamas. The aircraft was not observed on radar after the rapid descent. Upon notification that the aircraft was overdue, search and rescue protocols were initiated with coordination between the United States Coast Guard (USCG), Royal Bahamas Defence Force (RBDF), Royal Bahamas Police Force (RBPF), with assistance from the Bahamas Air Sea Rescue Association (BASRA). During search and rescue, aerial and marine assets from the US Coast Guard and RBDF responded to areas in vicinity of the last known position of the aircraft, initially identified at coordinates 25.84N 78.90W. An updated position of the aircraft was later provided by the US Coast Guard and identified at coordinates 25°20'35.00"N 76°59'46.00"W, at a distance of approximately 17 nautical miles southwest from MYEH. Assets also searched the updated position with combined search efforts extending up to 21st August 2023. As of the time of release of this report, neither the pilot nor the aircraft has been located.

The pilot was enroute to the destination airport and overflying the Gulf of Mexico when about 15 nautical miles from the airport and at an altitude of 3,000 ft, the right engine suddenly lost power. The pilot described that about that time, the fuel totalizers indicated that 48 gallons of fuel were onboard, and his fuel quantity gauge indicated similarly. He then contacted air traffic control and declared an emergency. Shortly thereafter, the left engine also suddenly lost power. The pilot attempted to troubleshoot the issue and restart both engines but was unsuccessful. He subsequently ditched the airplane and was rescued from the water without injury. The airplane was not recovered and could not be examined after the accident, therefore the reason for the loss of engine power could not be determined.

The airplane departed Veracruz-General Heriberto Jara Corona Airport Runway 01 at 2047LT on a private flight to Toluca, carrying one passenger and two pilots. Three minutes later, while climbing at night, it entered an uncontrolled descent until it crashed into the sea off Ciudad de Veracruz. The airplane was destroyed upon impact and all three occupants were killed.

The airplane was conducting a trans-Pacific flight when the accident occurred. A ferry fuel tank system was installed on the airplane and 1,189 gallons of fuel was added for the flight. About 4 hours into the flight over the Pacific Ocean, the crew contacted air traffic control (ATC) and reported that they were having a fuel transfer problem and were thinking of turning around. The crew then reported they were declaring an emergency and had 10 hours of fuel remaining but could only access about 2 hours of fuel. Satellite flight track data showed the airplane reversed course when it was about 356 miles from the California coast. About 132 miles from the coast the flight track decreases in altitude to about 4,000 ft above mean sea level (msl). The last few minutes of the data shows the altitude decrease from about 3,600 ft msl to about 240 ft msl. The last track data point was located about 33 miles off the California coast. The United States Coast Guard (USCG) responded to the accident location and reported the fuselage was inverted in the water. They reported the wings and engines were separated from the fuselage. The pilots were still strapped in their seats and unresponsive. The occupants were not recovered. Search efforts resulted in finding the nose landing gear, right wing, and right engine. A fuel bladder tank had washed ashore in southern California. Postaccident examination of the recovered components revealed no evidence of any preimpact mechanical malfunctions or failures that would have precluded normal operation. A mechanic reported that he was instructed to set up the ferry fuel tank system in the accident airplane. He installed but did not fill the system with fuel, as he did not know when the flight would take place and it would have been unsafe to have the bladders contain fuel for several days before the flight. After installing the ferry fuel tank system, he contacted the copilot (who was also a mechanic), who was then to complete the installation. The mechanic understood that the copilot would be responsible for the final installation of the ferry fuel tank system and complete the appropriate logbook entries. The mechanic was not present when the copilot completed the installation and was not sure if the copilot had signed off on it.

The accident airplane took off as the lead airplane in formation with a second Lear Jet airplane flying as wingman in a close formation position. The purpose of the flight was to participate in an exercise with the United States Navy in an over-water training area. Shortly after entering the training area at 15,000 ft mean sea level (msl) the wingman positioned on the right side of the accident airplane, observed the flaps on the accident airplane were partially extended. They notified the pilot of the accident airplane who acknowledged the radio call. The wingman then observed the flaps retract and observed white or gray colored “smoke or gas” coming from the left aft side of the airplane. The pilot in the accident airplane then radioed that they detected an odor in the cabin. Seconds later, the wingman observed red fluid on the underside of the tail cone followed by flames coming from around the aft equipment bay (tail cone) access door. They informed the accident pilots that their airplane was on fire and the accident pilot declared an emergency along with their intentions to land at a nearby airfield on the island. The wingman took over leading the formation and maneuvered in front of the accident airplane. The wingman last observed and heard radio transmissions from the accident airplane a short time later as they descended through about 7000 ft msl. The flight was above an overcast cloud layer that obstructed the view of the island at that time. Recorded ADS-B data showed that the accident airplane subsequently made a series of descending turns before the data ended. The airplane wreckage was located underwater about 4 miles northwest of the last ADS-B data point. The wreckage was highly fragmented, and the debris field extended several hundred feet along the ocean floor. Salvage operations were able to recover about 40 percent of the airplane wreckage. Examination of the wreckage showed areas of smoke and fire damage in portions of the airplane from the center wing fuselage outboard through the left- and right-wing roots and aft throughout the empennage. The aft equipment bay forward bulkhead, which also served as the fuselage fuel tank aft bulkhead, exhibited damage on the upper left side consistent with exposure to a focused heat source such as a fire from a leak in a pressurized fuel or hydraulic line. Additional evidence of focused fire damage was identified in the left engine pylon, which was located outboard and adjacent to the aft equipment bay. The effected area of the pylon contained engine fire detection circuits. Examination of the hydraulic shutoff valves attached to the hydraulic reservoir found that the left hydraulic shutoff valve was closed and the right valve was in the open position. The position of the left hydraulic shutoff valve indicates the aircrew likely shut down the left engine due to a fire indication (A hydraulic valve will close if the FIRE PULL tee-handle switch is activated by the flight crew in the event an engine fire is detected). Investigators were unable to determine if the witnessed flap extension and retraction was initiated by activation of the flap selector switch or induced by fire damage. The aft equipment bay houses electrical equipment capable of providing an ignition source for a fire, and hydraulic and fuel system components capable of providing fuel for a fire in the event of a leak. The left fuel motive flow line was intact from the fuel pump up to the fuselage fitting, where the line passes through the fuselage skin into the aft equipment bay near the aft left engine mount. The fuselage fitting had the stainless-steel fuel line and b-nut attached on the outboard, engine side. The inboard, aft equipment bay side of the fitting did not have an aluminum b-nut attached or the line that connects the fitting to the motive flow valve. The left engine hydraulic pressure line and PT2 line, which pass through the fuselage into the aft equipment bay adjacent to the motive fuel line, each had aluminum b-nuts present on the interior side of their respective fuselage fittings and the interior lines for each was sheared at the fitting. The left fuel motive flow fuselage fitting and the hydraulic fluid return fitting were examined. No thermal damage was observed on the outboard nuts and attached portions of tubing. Examination of the threads on the inboard side of the motive flow fitting did not exhibit evidence of thread stripping and comparison between the two fittings did not reveal any physical differences to explain why one nut remained attached and the other did not. The reason the motive flow nut was missing from the fitting could not be determined. Observed fire and heat damage patterns indicate the fire likely started in proximity to the where the pressurized fuel motive flow line connected to the firewall fitting where the missing b-nut was located. A leak from the pressurized motive flow line would have sustained and allowed an uncontrollable fire to develop. The sustained fire likely affected controllability of the airplane and resulted in the pilots’ loss of control of the airplane.

Radar contact was lost with the airplane while en route from Cumaná to Coro, heading 262° some 30 NM off Barcelona. The airplane failed to arrive at destination. SAR operations were initiated and no trace of the airplane nor the occupants was found.
