Investigation findings (A16P0186) into the October 2016 fatal accident of a Cessna Citation 500 near Kelowna, British Columbia
Findings as to causes and contributing factors
- The aircraft departed controlled flight, for reasons that could not be determined, and collided with terrain.
Findings as to risk
- If flight data, voice, and video recordings are not available to an investigation, the identification and communication of safety deficiencies to advance transportation safety may be precluded.
- If night and instrument proficiency are not adequately maintained, a pilot may not be able to recognize an aircraft upset and respond appropriately, especially during high-workload situations, increasing the risk of loss-of-control accidents.
- If weight-and-balance documents are inaccurate, there is a risk that aircraft will be operated outside of the allowable centre-of-gravity specifications, which could affect flight stability and controllability.
- If Transport Canada does not effectively oversee private operators, this sector of aviation may be exposed to higher risks that could lead to an accident.
Other findings
- Federal Aviation Administration Airworthiness Directive (AD) 79-12-06 requires that the upper and lower spar caps be inspected for cracking every 600 hours or 600 landings, whichever comes first, unless Cessna Service Bulletin SB57-10 Rev 4 is carried out. A review of the technical records for the aircraft determined that the last record of compliance for AD 79-12-06 was dated 21 December 2007, and had taken place 1062 hours and 1405 landings earlier.
- The investigation determined that there is no formal process in place at Transport Canada to assess and grant an operational approval for single-pilot operations on a Cessna Citation 500.
- Given that all components of the aircraft were accounted for at the wreckage site, the investigation concluded that there was no in-flight breakup or separation of the wing.
