The occurrence
On , a De Havilland DHC-3T aircraft, operated by Kississing Lake Lodge Ltd. (dba as Wings Over Kississing), was conducting a flight from Wollaston Lake Airport , Saskatchewan, to Points North Landing Airport, Saskatchewan.
After takeoff, the pilot was unable to reduce the engine power setting to climb power. All further attempts to reduce power had no effect. The pilot activated the emergency power lever, but it also had no effect. The pilot initiated a climb in an attempt to manage the airspeed.
The aircraft then proceeded to Points North Landing Airport; however, the airspeed increased to over 140 miles per hour, and the pilot’s side window shattered.
When in range of Points North Landing Airport, the pilot shut down the engine with the condition lever when the aircraft was at approximately 4000 feet above sea level.
The aircraft decelerated more quickly than anticipated and struck trees on final approach. It came to a stop beside the runway. The aircraft sustained substantial damage to the left wing, nose, and landing gear.
There were no injuries. The TSB is investigating.

Class of investigation
This is a class 3 investigation. These investigations analyze a small number of safety issues, and may result in recommendations. Class 3 investigations are generally completed within 450 days. For more information, see the Policy on Occurrence Classification.
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.
