NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

THE FLIGHT INSTRUCTOR WAS 'HAND PROPPING' THE ENGINE DUE TO AN INOPERATIVE STARTER SOLENOID. HIS STUDENT WAS IN THE LEFT COCKPIT SEAT, WORKING THE ENGINE CONTROLS. THE FIRST START ATTEMPT WAS UNSUCCESSFUL. THE INSTRUCTOR POSITIONED THE PROP FOR THE SECOND ATTEMPT, AND THE ENGINE FIRED. NO HAND SIGNALS WERE GIVEN PRIOR TO THE SECOND START ATTEMPT. THE PROPELLER CONTACTED THE INSTRUCTOR'S ARM AND LEG, RESULTING IN SERIOUS INJURIES. THE INSTRUCTOR BELIEVES THAT THE STUDENT DID NOT RETURN THE IGNITION SWITCH TO THE OFF POSITION AFTER THE FIRST START ATTEMPT, CONTRARY TO WHAT WAS BRIEFED.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

THE FLIGHT INSTRUCTOR'S FAILURE TO ENSURE THAT THE MAGNETOS WERE NOT ENERGIZED PRIOR TO POSITIONING THE PROPELLER, AND THE DUAL STUDENT'S FAILURE TO PLACE THE IGNITION SWITCH IN THE OFF POSITION AFTER THE FIRST START ATTEMPT.
