The post-accident examination revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation.
A GPS receiver was recovered from the accident, however, no data was recovered for the accident flight. Data from previous flights revealed flight maneuvers at low altitudes similar to the one described by witnesses.
