The occurrence

On , the PAL Airlines Ltd. Bombardier DHC-8-315 aircraft (registration C‑FPAE, serial number 562) departed Churchill Falls, Newfoundland and Labrador, as flight PVL1922 on an instrument flight rules flight to Deer Lake, Newfoundland and Labrador, with 4 crew members and 47 passengers on board.

At 1057 Newfoundland Standard Time, during the approach at Deer Lake, the flight crew selected the landing gear down; however, a weight on wheels caution light as well as advisory lights illuminated, indicating that the nose landing gear was not in the down‑and‑locked position. The flight crew executed a missed approach and entered a hold in order to troubleshoot the problem. At 1202, the flight crew requested a diversion to Stephenville, Newfoundland and Labrador, and declared an emergency. At 1230, the aircraft landed at Stephenville with the nose landing gear in a partially extended position. On touchdown, the nose landing gear fully collapsed, and the aircraft nose structure came into contact with the runway surface. The aircraft slid and came to a stop approximately halfway down the runway.

All occupants on board egressed the aircraft, and no injuries were reported. The aircraft sustained minor damage. There was no post-impact fire. The impact forces were insufficient to automatically activate the emergency locator transmitter. The accident occurred during the hours of daylight.

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.
