Aviation Investigation A15C0134

Collision with terrain

The occurrence

On 15 September 2015, at approximately 1822 Central Daylight Time, the Keystone Air Service Piper PA31-350, registration C-FXLO and operating as flight KEE208, departed Thompson, Manitoba on an IFR flight to Winnipeg, Manitoba.

Shortly after takeoff on Runway 06, the crew experienced a malfunction and alerted the Thompson Flight Service Station that they were returning for Runway 06. The aircraft collided with terrain approximately 1 nautical mile southwest of the Thompson airport. Emergency medical services crews responded to the scene and all 8 occupants survived and were taken to hospital with varying injuries.

Map of the area

Work to date

A large number of technical and operational documents have been gathered and are being reviewed by investigation team members. Numerous interviews have been conducted with crew, passengers and individuals from various organizations.

What we know


The ongoing investigation has confirmed that the aircraft received an incorrect type of fuel in Thompson, Manitoba, prior to departing for Winnipeg. The twin piston-engine aircraft requires aviation gasoline (AvGas), but was re-fueled with turbine engine fuel (Jet A1).

Post-impact damage

The aircraft was destroyed by impact with trees and terrain; however, the aircraft cabin section remained largely intact. Almost all of the fuel was dispersed throughout the crash site from ruptured fuel cells but a sufficient quantity remained to obtain samples. There was no post-impact fire.

Next steps

Work will include:

  • Further examination of aircraft fueling procedures and practices.
  • Conducting additional interviews as required.
  • Additional examination of aircraft wreckage.
  • Laboratory analysis of fuel samples.

Transportation Safety Board investigation process

There are 3 phases to a TSB investigation:

  1. Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
  2. Examination and analysis phase: the TSB reviews pertinent records, tests components of the wreckage in the lab, determines the sequence of events and identifies safety deficiencies. When safety deficiencies are suspected or confirmed, the TSB advises the appropriate authority without waiting until publication of the final report.
  3. Report phase: a confidential draft report is approved by the Board and sent to persons and corporations who are directly concerned by the report. They then have the opportunity to dispute or correct information they believe to be incorrect. The Board considers all representations before approving the final report, which is subsequently released to the public.
