KRMG is learning more about the twin-engine Mitsubishi MU-2B airplane that Dr. Perry Inhofe, son of Sen. Jim Inhofe, was flying when he crashed and died Sunday afternoon.

Aviation attorney and pilot Ladd Sanger has seen the crash site and says the plane's design likely caused the crash.

Sanger believes, based on the evidence he has seen that one of the plane's engines had failed prior to landing. Sanger says,"The aerodynamics of the wing design make approach and landings single engine operations challenging or even impossible."

Sanger cites NTSB statistics and Mitsubishi production records that show approximately one-third of the MU-2 fleet has been involved in an accident and approximately a quarter of the fleet has been involved in a fatal accident.
