What happened
A privately owned Cessna 414A, registration C-GENG, departed Toronto/Buttonville Municipal Airport, Ontario, bound for Sydney, Nova Scotia, under instrument flight rules. The flight carried the aircraft owner and a pilot-in-command who had recently completed a brief familiarization session with the aircraft type.
While conducting an RNAV approach to Sydney J.A. Douglas McCurdy Airport, the pilot was instructed by Moncton Area Control Centre to hold due to conflicting traffic and was advised to reduce airspeed. The aircraft failed to slow down and, following a specific instruction to turn right, instead turned left. This maneuver led to an erratic flight path characterized by frequent heading changes and altitude deviations of up to 500 feet. The aircraft eventually entered a rapid descent and impacted the water at 2335 Atlantic Daylight Time. The wreckage was discovered 11 days later in 170 feet of water. The impact resulted in two fatalities.
The investigation
Investigators examined the flight history, the aircraft's mechanical condition, and the environmental factors present during the approach. The investigation ruled out engine or flight control failures, as no deficiencies were found in the wreckage. Additionally, the investigation dismissed turbulence as a cause due to stable weather conditions, and ruled out carbon monoxide poisoning because the aircraft heater had been recently serviced and the pilot showed no signs of impairment during radio communications.
Because the aircraft's technical logs were carried on board and lost in the crash, investigators were unable to review the full maintenance history since the aircraft's recent acquisition. The absence of onboard recording devices also prevented a definitive determination of whether the pilot or the owner was physically controlling the aircraft at the moment of the accident.
Findings
- The crew likely experienced spatial disorientation during the final stages of the flight, leading to a loss of control and a spiral dive.
- The pilot's workload was increased after declining radar vectors and failing to follow instructions regarding airspeed and heading.
- Self-imposed pressure to meet a scheduled business meeting likely drove the decision to fly despite the crew's lack of experience with the aircraft type, the unfamiliarity with the destination, and the fatigue following a 15-hour travel day.
- Task saturation, potentially exacerbated by the need to reprogram the GPS and manage the approach, contributed to the degradation of situational awareness.
