Aviation Investigation A15A0054

Runway excursion, Beech King Air A100, Margaree, Nova Scotia

The occurrence

On 16 August 2015, a Beech King Air A100 was on a charter flight from Halifax, Nova Scotia, to Margaree, Nova Scotia, with 2 passengers and 2 crew aboard. The aircraft landed hard on Runway 01 at the Margaree Airport about 263 feet from the threshold. The right main landing gear collapsed and the right propeller first contacted the runway surface 82 feet beyond the initial runway contact point. The aircraft remained on the runway surface with the right wing, engine nacelle and propeller in contact with the surface until approximately 1700 feet down the 2500-foot-long runway. At this point, the aircraft veered off the right side of the runway at approximately a 30-degree angle to the runway heading. The final resting position of the aircraft was 1850 feet from the threshold of Runway 01, 22 feet from the runway edge and 90 degrees from the runway heading. There were no injuries.

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.
