The occurrence
On 07 September 2023, a Fairchild SA227-DC aircraft operated by Perimeter Aviation GP Inc. was conducting a flight from Toronto/Lester B. Pearson International Airport, Ontario, to North Bay/Jack Garland Airport, Ontario, and then to Detour Lake Aerodrome, Ontario.
During the landing Detour Lake Aerodrome, the aircraft’s right wing impacted with the runway in nose down attitude, which resulted in the right main and nose landing gears collapsing. The damage from the impact caused a loss of control and the aircraft veered to the right and slid down the runway embankment, coming to rest in an upright position.
The 2 crew members and 8 passengers were able to exit the aircraft. One crew member and 3 passengers sustained minor injuries. The aircraft sustained significant damage to the landing gear, engines, propellers, wings, and fuselage. There was no post-crash fire. The emergency locator transmitter was not activated.
The TSB is investigating.

Class of investigation

TSB 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.

The TSB is an independent agency that investigates air, marine, pipeline, and rail transportation occurrences. Its sole aim is the advancement of transportation safety. It is not the function of the Board to assign fault or determine civil or criminal liability.
