The crew was completing a local test flight at Gavião Peixoto-Embraer Unidade Airport on this first prototype built in 2015 and flying under the Brazilian Air Force colour scheme. Following several circuits, the crew landed on runway 20. After touchdown, the airplane was unable to stop within the remaining distance and overran. While contacting soft ground, it lost its undercarriage and came to rest few dozen metres further. All three crew members escaped uninjured while the aircraft was considered as damaged beyond repair.

The crew departed Bogotá on a training flight to Mariquita with an intermediate stop at Ibagué-Perales Airport. While on approach by night, the twin engine aircraft went out of control and crashed in a field located few km from the airport, bursting into flames. The aircraft was totally destroyed by a post crash fire and all four crew members were killed.

National Oil Corporation confirms a C-130 aircraft chartered by Akakus Oil crashed during take-off, 2 km from the Sharara oil field, after delivering 18 tonnes of catering and maintenance supplies. The crash occurred at 12:25pm on Sunday, April 29, 2018. Firefighters and paramedics quickly rushed to the scene. The tragic incident resulted in the death of three crew members and the injury of one other who is being evacuated by air to receive medical treatment in Tripoli. The NOC Board of Directors cancelled all their commitments and are presently at Akakus headquarters meeting with local management and a number of emergency staff to follow up on this tragic incident. The circumstances of the crash are still being investigated. Mr. Fayez Al-Sarraj, Chairman of the Presidential Council, was briefed on the developments of the incident, and expressed his solidarity with the families of the victims, ordering the preparation of a decree commemorating the deceased as martyrs. The General Civil Aviation Authority (GCAA) was also briefed and offered its condolences to the Chief of Staff of the Air Force. The plane in question is the property of the Libyan Air Force but was chartered by Akakus Oil, who operate the Sharara field. The company was forced to charter the aircraft due to road closures and the security situation on the ground stemming from a road blockade leading to the field.

The aircraft was completing a humanitarian mission, carrying five crew members and a load of various goods. After landing, the aircraft was unable to stop within the remaining distance. It overran, lost its left main gear and came to rest. All five occupants evacuated safely and the aircraft was damaged beyond repair.

The aircraft was engaged in a troop transport from Boufarik to Tindouf with an intermediate stop in Béchar, west Algeria, and was carrying 247 soldiers and their family members and 10 crew members. Shortly after takeoff from the Boufarik AFB located some 25 km southwest of Algiers, while climbing to a height of about 150 meters, the aircraft entered an uncontrolled descent and crashed in an agricultural zone located near the airport, bursting into flames. The airplane was totally destroyed by impact forces and a post crash fire. It was quickly confirmed by the Algerian Authorities that none of the 257 occupants survived the crash, among them 26 members of the Front Polisario. According to first testimonies, it appears that the left wing (engine?) was on fire when control was lost.

The airplane departed Kuweires-Rasin El Aboud Airbase on a flight to Hmeimim AFB, carrying 33 passengers and a crew of six. On final approach, the aircraft went out of control and crashed about 500 metres short of runway, bursting into flames. There were no survivors among the 39 occupants. The airplane was registered RF-92955 (52 red). It is believed that the loss of control that occurred on short final was the result of low level windshear.

The airline transport pilot and two passengers departed in the twin-engine, pressurized airplane on a business flight in night instrument meteorological conditions. Shortly after takeoff, the airplane began to deviate from its assigned altitude and course. The controller queried the pilot, who responded that the airplane was "… a little out of control." After regaining control of the airplane, the pilot reported that he had experienced a "trim issue." The airplane continued on course and, about 13 minutes later, the pilot again reported a trim malfunction and said that he was having difficulty controlling the airplane. The flight's heading and altitude began to deviate from the course for the last 8 minutes of radar data and became more erratic for the last 2 minutes of radar data; radar and radio communication were subsequently lost at an altitude of about 18,300 ft in the vicinity of the accident site. Several witnesses reported hearing the airplane flying overhead. They all described the airplane as being very loud and that the engine sound was continuous up until they heard the impact. The airplane impacted a field in a relatively level attitude at high speed. The wreckage was significantly fragmented and the wreckage path extended about 1/4 mile over several fields. Examination of the available airframe and engine components revealed no anomalies that would have precluded normal operation of the airplane. The accident airplane was equipped with elevator, rudder, and aileron trim systems; however, not all components of the trim system and avionics were located or in a condition allowing examination. Although the airplane was equipped with an electric elevator trim and autopilot that could both be turned off in an emergency, the investigation could not determine which trim system the pilot was reportedly experiencing difficulties with. It is likely that the pilot was unable to maintain control of the airplane as he attempted to address the trim issues that he reported to air traffic control.

While completing a training mission, the airplane crashed in unknown circumstances near the Zhengchang village, in the Guizhou Province. The PLA Air Force Y-8GX4 Electronic Intelligence (ELINT) aircraft, registered 30513, was assigned to the PLAAF 20th Special Missions Division. The Y-8G fleet of the division is reportedly based close to the crash site. The airplane was totally destroyed by impact forces and a post crash fire and all 12 occupants were killed.

The twin engine aircraft departed Eskişehir Airport at 1103LT on a training flight, carrying one technician and two pilots. While flying in good weather conditions, the airplane struck the top of a snow covered mountain located in the region of Yalvaç, some 80 km northeast of Isparta. The wreckage was found at 1430LT. All three crew members were killed.

The airplane departed Ankara-Esenboğa Airport at 2233LT bound for Trabzon. Following an uneventful flight, the crew started the approach by night to runway 11 and the landing was completed in heavy rain falls at 2325LT. After touchdown at a speed of 143 knots, the airplane rolled for about 2,400 metres then veered off runway to the left, went through a grassy area then down a steep slope. It lost its right engine and came to rest few metres above the sea. All 168 occupants evacuated safely. The right engine was sheared off and fell into the sea. According to first report, it is believed something went wrong with the right engine after touchdown (unintentional forward thrust and asymmetrical thrust).
