Aircraft involved
Probable cause & findings
FAILURE OF THE PILOT TO ATTAIN SUFFICIENT LIFT OFF AIRSPEED. FACTORS IN THIS ACCIDENT WERE THE PILOT'S OVERCONFIDENCE IN HIS PILOTING SKILLS, AND THE INADVERTENT STALL OF THE AIRPLANE.
Factual narrative
THE PILOT STATED THAT DURING THE TAKEOFF ROLL HE GLANCED AT THE LIFT RESERVE INDICATOR WHICH INDICATED THAT HE HAD ENOUGH LIFT TO FLY. THE AIRPLANE IS MODIFIED WITH A WREN 460 STOL KIT. THE AIRSPEED OF THE AIRPLANE WAS APPROXIMATELY 35-40 KNOTS. SHORTLY AFTER TAKEOFF, THE AIRPLANE BEGAN A LEFT ROLLING MOTION. THE AIRPLANE DID NOT RESPOND TO ANY CORRECTIVE ACTION INITIATED BY THE PILOT. THE AIRPLANE STRUCK THE GROUND, LEFT WING TIP FIRST AND CAME TO REST BETWEEN THE TWO RUNWAYS. IN AN INTERVIEW WITH FAA INSPECTORS, THE PILOT STATED THAT THE 'STALL WARNING HORN WAS GOING OFF AS USUAL,' BUT HE CHOSE TO 'IGNORE IT AS USUAL.' ACCORDING TO THE WREN OPERATIONS MANUAL FOR THE AIRCRAFT, THE NORMAL TAKEOFF SPEED IS 60 MPH, AND A CLIMB SPEED OF 90 MPH.
