The aircraft departed Palanquero AFB on a flight to Barranquilla with an intermediate stop in Valledupar. While cruising in poor weather conditions, the crew informed ATC about an engine failure when radio contact was lost. The aircraft entered an uncontrolled descent and crashed in a field located near Agustín Codazzi, some 50 km south of Valledupar. The aircraft was totally destroyed by impact forces and there was no fire. All 11 crew members were killed. The airplane was completing a special mission on behalf of the Colombian Intelligence Forces.

The crew was performing a training/reconnaissance mission out from Ukrainka AFB. While cruising at an altitude of 5,000 metres in clouds and icing conditions, three of the four engines failed. At an altitude of 3,500 metres, all seven crew members bailed out and the aircraft crashed in a tundra located some 30 km from Litovko, Amur district of the Khabarovsk region. Five crew members survived while two others were killed. The registration of the 'Bear' was dual RF-94204 and 77 Red.

The single engine aircraft departed Kodinsk at 1400LT on a survey flight, carrying five fire bombers and four crew members (two pilots and two observers). About two hours into the flight, the occupant spotted a fire. All five fire bombers were dropped with their materials in two groups. Then the crew increased engine power and continued at an altitude of about 150-200 metres. The engine oil temperature started to increase and reached 150°. Five minutes later, the engine failed. The crew attempted an emergency landing when the aircraft impacted 20 metres tall trees, stalled and crashed in a wooded area. The wreckage was found south of Kezhma, some 126 km east of Kodinsk. All four occupants evacuated safely and the aircraft was destroyed.

The single engine aircraft was engaged in a crop spraying mission on behalf of the Mikhail Farm located in the Tatsinsky District of the Rostov Region. The aircraft was carrying 400 kilos of fuel, 1,200 liters of pesticides, one pilot and one boy aged 13, the son of the farmer. Few minutes after takeoff, while approaching the area to be treated at a height of about 20-25 metres and at a speed of 130 km/h, the engine failed. The aircraft lost height, collided with power cables and crashed in a field, bursting into flames. The wreckage was found 2 km from the Mikhail farmhouse. The pilot escaped unhurt while the boy was injured. The aircraft was totally destroyed by a post crash fire.

The twin engine aircraft was engaged in a post-maintenance test flight out from Santiago de Querétaro Airport, carrying three engineers and two pilots. It departed runway 09 at 1421LT and the crew was cleared to climb to FL125. While approaching the altitude of 12,000 feet, the aircraft entered an uncontrolled descent and crashed on a motorway located 11 km southwest of the airport, bursting into flames. The aircraft was totally destroyed by impact forces and a post crash fire and all five occupants were killed.

The twin engine airplane departed Miranda-Estância Caimam Airfield at 0915LT on a charter flight to Campo Grande, carrying seven passengers and two pilots. About 35 minutes into the flight, while flying 79 km from the destination in good weather conditions, the left engine failed. The crew was unable to feather the propeller and to maintain a safe altitude, so he decided to attempt an emergency landing. The aircraft belly landed in an agriculture area, slid for few dozen metres and came to rest. All nine occupants suffered minor injuries and the aircraft was damaged beyond repair.

The crew took off from a small airfield located in the suburb of Manaus at the end of the day with a load of 616 small packages containing cocaine. After entering the Venezuelan Airspace without clearance, the crew was contacted twice by ATC but failed to answer. Authorities decided to send two fighters to establish a visual and radio contact with the crew but without success as, due to the low visibility caused by night and poor weather conditions, the crew of the Navajo was able to continue the flight without further problem. Nevertheless, three hours later, the twin engine aircraft was again localized passing over the State of Cojedes, and the decision was taken to shoot it down. Out of control, the Navajo crashed in a pasture located in the region of Ricaurte, and was totally destroyed by impact forces. Both pilots were killed and a load of narcotics was found. At the time of the accident, the aircraft was illegally registered YV1246 as a sticker has been affixed above the official Brazilian registration PT-RCN.

Crashed in unknown circumstances near Cañaote, State of Cojedes. The wreckage was found the following morning. The aircraft was destroyed, all three occupants were killed and a load of 999 kilos of cocaine was found among the debris.

The crew was performing an illegal flight, most probably from Belarus, with a load of cigarettes on board. By night, he was attempting to land in a field located in Promin when the single engine aircraft impacted the roof of a house and crashed on a small road, bursting into flames. The aircraft was destroyed by a post crash fire and both occupants were killed.

The pilot reported that, during the postmaintenance test flight, the turboprop engine lost power. The airplane was unable to maintain altitude, and the pilot conducted a forced landing, during which the airplane was substantially damaged. The engine had about 9 total flight hours at the time of the accident. A teardown of the fuel pump revealed that the high-pressure drive gear teeth exhibited wear and that material was missing from them, whereas the driven gear exhibited little to no visible wear. A metallurgical examination of the gears revealed that the damaged drive gear was made of a material similar to 300-series stainless steel instead of the harder specified M50 steel, whereas the driven gear was made of a material similar to the specified M50 steel. Subsequent to these findings, the airplane manufacturer determined that the gear manufacturer allowed three set-up gears made from 300-series stainless steel to become part of the production inventory during the manufacturing process. One of those gears was installed in the fuel pump on the accident airplane, and the location of the two other gears could not be determined. Based on the evidence, it is likely that the nonconforming gear installed in the fuel pump failed because it was manufactured from a softer material than specified, which resulted in a loss of fuel flow to the engine and the subsequent loss of engine power. The manufacturer subsequently inspected its stock of gears and issued notices to customers that had engines with fuel pumps installed with the same part number gear set as the one installed on the accident airplane. The manufacturer also issued a service information letter and service bulletins regarding the fuel pump gear set for engines used in civilian and military applications. As of the date of this report, the two remaining gears have not been located.
