The occurrence

On , a de Havilland DHC-2 Beaver aircraft was conducting float training operations on Terrington Basin near the Goose (Otter Creek) Seaplane Base, Newfoundland and Labrador, with 2 pilots on board. During the landing, the front of the left float dug in, causing the aircraft to cartwheel and flip inverted. One of the pilots found himself in the rear of the cabin and had difficulty getting out, and needed the assistance of the other pilot who had exited from the front of the aircraft and opened the rear cargo door. Both pilots were rescued by a nearby boat. The aircraft was substantially damaged.

TSB 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.

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.
