Findings as to Causes and Contributing Factors
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.
The PIC did not accept assistance in the form of radar vectors, which contributed to the workload during the approach.
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.
It could not be conclusively determined who was flying the aircraft at the time of the occurrence.
The lack of onboard recording devices prevented the investigation from determining the reasons why the aircraft departed controlled flight.
The practice of placing aircraft technical records on board aircraft may impede an investigation if the records are lost due to an accident.
This report concludes the Transportation Safety Board’s investigation into this occurrence. Consequently, the Board authorized the release of this report on 23 June 2011.
