Loss of control
Airspan Helicopters B212, C-GNYI (helicopter)
Bowen Island, British Columbia
On , C-GNYI, a Bell 212 helicopter operated by Airspan Helicopters Ltd. was travelling from Sechelt Airport (CAP3), British Columbia, to Cypress Mountain Provincial Park, located in West Vancouver, British Columbia, to support a BC Hydro project. Two pilots were on board. During the flight, the aircraft experienced a sudden and dramatic right roll and nose down pitch. Both pilots attempted to regain control of the aircraft. When they had done so, they observed warning lights indicating a hydraulic failure and an engine failure. A location on nearby Bowen Island was selected for an emergency landing. However, the aircraft was still difficult to control and the crew was unable to manoeuvre it to the desired location. During the descent, the aircraft began an uncommanded rotation, leading to a loss of control. The aircraft collided with trees and came to rest on a rocky ridge on the northwest corner of Bowen Island. Both occupants received minor injuries. There was no fire. The emergency locator transmitter functioned as designed. The TSB is investigating.

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.
