NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.

THE AIRCRAFT CRASHED AFTER TAKING OFF ON A TEST FLIGHT. A WITNESS REPORTED THAT THE AIRCRAFT WAS IN A STEEP ANGLE OF CLIMB, AND THE NOSE PITCHED DOWN AS THE PILOT WAS MAKING A LEFT TURN. THE WITNESS REPORTED THAT THE PILOT HAD BEEN ADJUSTING THE MAGNETOS PRIOR TO TAKEOFF. HOWEVER, NO PREIMPACT FAILURE OF THE ENGINE OR AIRFRAME WAS FOUND. BOTH MAGNETOS WERE DRIVEN CLOCKWISE ON THE ENGINE, AND BOTH PRODUCED A GOOD SPARK WHEN BENCH TESTED. HOWEVER, THE RIGHT MAGNETO DISTRIBUTOR GEAR AND BREAKER WERE SET FOR COUNTERCLOCKWISE ROTATION. THE LEFT MAGNETO DISTRIBUTOR GEAR WAS SET IN A CLOCKWISE POSITION, WHILE THE RESPECTIVE BREAKER CAM WAS SET FOR COUNTERCLOCKWISE ROTATION. DUE TO ENGINE DAMAGE, MAGNETO-TO-ENGINE TIMING COULD NOT BE CHECKED. BOTH MAGNETOS HAD BEEN SET AT THE LIMITS OF THEIR MOUNTING SLOTS ON THE ENGINE.
