Aircraft flight hours:

Circumstances:
Aircraft was on a flight from Toronto-Lester B. Pearson International Airport to Toronto-Buttonville Municipal Airport, Ontario, with 2 pilots on board. Air traffic control cleared the aircraft for a contact approach to Runway 33. During the left turn on to final, the aircraft overshot the runway centerline. The pilot then compensated with a tight turn to the right to line up with the runway heading and touched down just beyond the threshold markings. Immediately after touchdown, the aircraft exited the runway to the right, and continued through the infield and the adjacent taxiway Bravo, striking a runway/taxiway identification sign, but avoiding aircraft that were parked on the apron. The aircraft came to a stop on the infield before Runway 21/03. The aircraft remained upright, and the landing gear did not collapse. The aircraft sustained substantial damage. There was no fire, and the flight crew was not injured. The Toronto-Buttonville tower controller observed the event as it progressed and immediately called for emergency vehicles from the nearby municipality. The accident occurred at 1506 Eastern Daylight Time.
Probable cause:
Findings as to Causes and Contributing Factors:
1. The crew flew an unstabilized approach with excessive airspeed.
2. The lack of adherence to company standard operating procedures and crew resource management, as well as the non-completion of checklist items by the flight crew contributed to the occurrence.
3. The captain’s commitment to landing or lack of understanding of the degree of instability of the flight path likely influenced the decision not to follow the aural GPWS alerts and the missed approach call from the first officer.
4. The non-standard wording and the tone used by the first officer were insufficient to deter the captain from continuing the approach.
5. At touchdown, directional control was lost, and the aircraft veered off the runway with sufficient speed to prevent any attempts to regain control.
Finding as to Risk
1. Companies which do not have ground proximity warning system procedures in their standard operating procedures may place crews and passengers at risk in the event that a warning is received.

Circumstances:
The privately owned Cessna 414A departed Toronto/Buttonville Municipal Airport, Ontario, en route to Sydney, Nova Scotia. The flight was operating under an instrument flight rules flight plan with the pilot-in-command and the aircraft owner on board. Nearing Sydney, the aircraft was cleared to conduct an instrument approach. At the final approach waypoint the pilot was advised to discontinue the approach due to conflicting traffic. While manoeuvring for a second approach, the aircraft departed from controlled flight, entered a rapid descent and impacted the water at 2335 Atlantic Daylight Time. The aircraft wreckage was located using a side-scan sonar 11 days later, in 170 feet of water. The aircraft had been destroyed and both occupants were fatally injured. No signal was detected from the emergency locator transmitter.
Probable cause:
Findings as to Causes and Contributing Factors:
1. It is likely that the PIC and the owner were both suffering some degree of spatial disorientation during the final portion of the flight. This resulted in a loss of control of the aircraft and the crew was unable to recover prior to contacting the surface of the water.
2. The PIC did not accept assistance in the form of radar vectors, which contributed to the workload during the approach.
3. Self-imposed pressure likely influenced the crew’s decision to depart Buttonville despite the flight conditions, lengthy day, and lack of experience with the aircraft and the destination airport.
Other Findings:
1. It could not be conclusively determined who was flying the aircraft at the time of the occurrence.
2. The lack of onboard recording devices prevented the investigation from determining the reasons why the aircraft departed controlled flight.
3. The practice of placing aircraft technical records on board aircraft may impede an investigation if the records are lost due to an accident.
