The final report of the National Transportation Safety Board (NTSB) identifies a left banking turn of 87 degrees as the cause of a stall and subsequent ground impact. The manufacturer’s maximum angle of bank is 60 degrees, and operators are warned by the manufacturer against ever exceeding this limit. There was no evidence of engine or airframe malfunction, or any other contributing cause.
