Aviation Investigation A16P0186
Collision with terrain
On 13 October 2016, a Cessna C500 (Citation) departed Kelowna Airport (CYLW) at 21:32 PDT for a flight to Calgary/Springbank Airport (CYBW). The aircraft disappeared off the radar. RCMP located the accident site north of Kelowna, east of Wood Lake, British Columbia, and confirmed that all persons on board had perished. There were no emergency calls or signals.

What we know
Update: 19 October 2016
The examination and documentation of the wreckage scene is complete and investigators have collected the data they needed from the accident site. The wreckage will be removed by helicopter and transported to a facility for further analysis.
With the conclusion of the Field Phase begins the Examination and Analysis Phase. TSB investigators from across Canada are involved in helping with this ongoing investigation. While there are no definitive findings to report at this time, there are some important next steps.
In the coming days and weeks, the team will:
Working with others
The TSB conducts independent investigations. However, we would like to recognize the contribution of other organizations:
Absence of flight data recorder and cockpit voice recorder
The absence of a Cockpit Voice Recorder (CVR) or a Flight Data Recorder (FDR) will make this investigation particularly challenging.
The privately-operated Cessna Citation involved in the crash was not equipped with, nor was it required to carry, a CVR or FDR. In Canada, only multi-engine, turbine-powered commercial aircraft flown by two pilots and carrying six or more passengers are required to carry a CVR on board.
As early as 1991, the Board made a recommendation calling for the upgrade of flight recorder requirements.
Following TSB investigation A88O0491, the Board issued the following recommendation in 1991:
The Department of Transport expedite legislation for upgrading the flight recorder requirements for Canadian-registered aircraft.
Since then, the aviation industry has developed several different lightweight flight recording systems which could be installed in smaller aircraft at a low cost. These flight recording systems could be used by accident investigators to identify safety deficiencies and reduce risk in a timely manner.
As part of TSB investigation A11W0048, in 2013 the Board recommended that:
The Department of Transport work with industry to remove obstacles to and develop recommended practices for the implementation of flight data monitoring and the installation of lightweight flight recording systems by commercial operators not currently required to carry these systems.
The TSB urges the industry and private corporate aircraft owners to take advantage of the new, low-cost flight recording technology to advance safety in their operations.
Communication of safety deficiencies
Investigations are complex and we take the time needed to complete a thorough investigation. However, should the investigation team uncover safety deficiencies that present an immediate risk, the Board will communicate them without delay.
Further, it is important not to draw conclusions or speculate as to causes at this time. There are often many factors that can contribute to an accident.
Beverley Harvey has 30 years of civil aviation experience. She joined the TSB in 2008 as an investigator/operations specialist in the TSB Air Investigations Branch at Head Office, Gatineau, Quebec.
Prior to joining the TSB, she was an inspector at Transport Canada, and a pilot with a commuter airline. During that time she flew different aircraft types, from small aircraft to larger commuter aircraft.
Since joining the TSB, Ms. Harvey has participated in several TSB investigations. On behalf of the TSB, she has assisted foreign investigation agencies in their investigations of accidents abroad.

Transportation Safety Board 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.
