Following an uneventful flight, the crew was returning to Schefferville Airport when the twin engine aircraft crashed in unknown circumstances in a snow covered field located north of the city. The wreckage was found few hours later and both occupants were killed. According to preliminary report, the left engine hit power cables that were found twisted around the left propeller.

Circumstances:
The single engine airplane departed Cali-Alfonso Bonilla Aragón Airport on an geophysical exploration mission of the south part of Chocó, carrying three crew members, two pilots and one operator in charge of the LIDAR equipment. At 1144LT, the crew reported his altitude at 5,600 feet. Two minutes later, while cruising in poor visibility, the aircraft struck trees and crashed in wooded and hilly terrain near Yambo. The wreckage was found few hours later and all three occupants were killed.
Probable cause:
The following factors were identified:
- Controlled flight into terrain,
- Execution of a VFR flight in reduced visibility weather conditions,
- Poor decision making by the crew in continuing VFR operation as they were in an environment of significantly reduced visibility,
- Inadequate operational risk assessment due to the lack of familiarity of the foreign crew with the topography and meteorological evolution of the sector.

Circumstances:
The twin engine aircraft departed Bucaramanga-Palonegro Airport at 0804LT on a geophysical mission over the Coromoro Region, Santander. At 1000LT, the last radio contact was recorded with the pilot. While flying in marginal weather conditions (low clouds), the aircraft impacted the slope of a mountain located near Coromoro. The wreckage was found two days later at an altitude of 4,500 metres, some 98 km south of Bucaramanga. The aircraft disintegrated on impact and both occupants were killed, among them Peter Moore, co-founder of Oracle Geoscience International and Neville Ribeiro, the pilot.
Probable cause:
Controlled flight into terrain after the pilot was flying under VFR mode in IMC conditions. It was determined that the accident occurred after the pilot suffered a loss of situational awareness while flying under VFR mode in low clouds conditions.

Circumstances:
The twin aircraft departed Guanambi Airport to perform a low level survey flight in the region of Espinosa, carrying two observers and one pilot. About two hours into the flight, while cruising at an altitude of 330 feet, the right engine lost power then failed. While executing the emergency checklist, the left engine failed as well. The pilot attempted an emergency landing when the aircraft crashed in a wooded area, bursting into flames. Both passengers evacuated with minor injuries and the pilot was killed. The aircraft was totally destroyed by a post crash fire.
Probable cause:
There was sufficient fuel in the tanks at the time of the accident as the aircraft was refueled prior to departure for a 5-hour flight. The exact cause of the double engine failure remains unknown. When the right engine failed, the pilot was flying at an altitude of 330 feet which was below the minimum safe altitude fixed at 500 feet. Also, he was apparently using his cell phone.

Circumstances:
At 1503 Central Standard Time, the Construcciones Aeronauticas SA (CASA) C-212-CC40 (registration C-FDKM, serial number 196) operated by Fugro Aviation Canada Ltd., departed from Saskatoon/Diefenbaker International Airport, Saskatchewan, under visual flight rules for a geophysical survey flight to the east of Saskatoon. On board were 2 pilots and a survey equipment operator. At about 1814, the right engine lost power. The crew shut it down, carried out checklist procedures, and commenced an approach for Runway 27. When the flight was 3.5 nautical miles from the runway on final approach, the left engine lost power. The crew carried out a forced landing adjacent to Wanuskewin Road in Saskatoon. The aircraft impacted a concrete roadway noise abatement wall and was destroyed. The survey equipment operator sustained fatal injuries, the first officer sustained serious injuries, and the captain sustained minor injuries. No ELT signal was received.
Probable cause:
Conclusions
Findings as to Causes and Contributing Factors:
1. The right engine lost power when the intermediate spur gear on the torque sensor shaft failed. This resulted in loss of drive to the high-pressure engine-driven pump, fuel starvation, and immediate engine stoppage.
2. The ability of the left-hand No. 2 ejector pump to deliver fuel to the collector tank was compromised by foreign object debris (FOD) in the ejector pump nozzle.
3. When the fuel level in the left collector tank decreased, the left fuel level warning light likely illuminated but was not noticed by the crew.
4. The pilots did not execute the fuel level warning checklist because they did not perceive the illumination of the fuel level left tank warning light. Consequently, the fuel crossfeed valve remained closed and fuel from only the left wing was being supplied to the left engine.
5. The left engine flamed out as a result of depletion of the collector tank and fuel starvation, and the crew had to make a forced landing resulting in an impact with a concrete noise abatement wall.
Findings as to Risk:
1. Depending on the combination of fuel level and bank angle in single-engine uncoordinated flight, the ejector pump system may not have the delivery capacity, when the No. 1 ejector inlet is exposed, to prevent eventual depletion of the collector tank when the engine is operated at full power. Depletion of the collector tank will result in engine power loss.
2. The master caution annunciator does not flash; this leads to a risk that the the crew may not notice the illumination of an annunciator panel segment, in turn increasing the risk of them not taking action to correct the condition which activated the master caution.
3. When cockpit voice and flight data recordings are not available to an investigation, this may preclude the identification and communication of safety deficiencies to advance transportation safety.
4. Because the inlets of the ejector pumps are unscreened, there is a risk that FOD in the fuel tank may become lodged in an ejector nozzle and result in a decrease in the fuel delivery rate to the collector tank.
Other Findings:
1. The crew’s decision not to recover or jettison the birds immediately resulted in operation for an extended period with minimal climb performance.
2. The composition and origin of the FOD, as well as how or when it had been introduced into the fuel tank, could not be determined.
3. The SkyTrac system provided timely position information that would have assisted search and rescue personnel if position data had been required.
4. Saskatoon police, firefighters, and paramedics responded rapidly to the accident and provided effective assistance to the survivors.

Circumstances:
The crew was performing a supply mission in the Nunavut with three scientists on board. Equipped with ski, the aircraft landed on the snow covered terrain some 168 km north of Alert Air Base. After landing, the aircraft came to a halt when the right ski punctured the ice and the aircraft partially sunk while both engines were still running. All five occupants escaped uninjured and were evacuated two hours later by the crew of a Bell 407 to Resolute Bay. Damaged beyond repair, the aircraft was abandoned on site and later cancelled from registry in November 2011.
Probable cause:
Landing gear went through the ice after landing on ice/snow terrain.
