Aviation Investigation A17Q0050
Collision with terrain
On April 30, 2017, C-FQQB, a Piper PA-31 Navajo operated by Exact Air, was conducting its second magnetometric survey flight of the day from Schefferville, Quebec, with two pilots on board. The crew was accompanied by C-FVTL, another Piper PA-31 from the same air operator. C-FQQB took off at approximately 13:36 for a flight of approximately 5 hours, followed by C-FVTL. Around 6:55 pm, C-FQQB was reported missing by the C-FVTL crew and research was launched. The aircraft was located approximately 3.5 nautical miles (nm) from the Schefferville Airport. The two pilots of C-FQQB sustained fatal injuries. The TSB is investigating.

Transportation Safety Board investigation process
There are 3 phases to a TSB investigation:
- Field phase: a team of investigators examines the occurrence site and wreckage, interviews witnesses and collects pertinent information.
- 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.
- 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.
