THE PILOT LANDED ON A GRAVEL BAR TO AWAIT BETTER WEATHER. THE GRAVEL BAR WAS 375 FEET LONG. THE PLANE NORMALLY REQUIRED A TAKEOFF DISTANCE OF 400 FEET. THE PILOT BELIEVED THAT THE TAKEOFF COULD BE MADE BASED UPON THE 5 TO 10 MILE PER HOUR HEADWIND, HAVING NO PASSENGERS, AND 3/4THS FUEL. AT THE END OF THE GRAVEL BAR THE PLANE'S INDICATED AIRSPEED WAS ABOUT 40 MILES PER HOUR. NORMAL LIFTOFF AIRSPEED WAS APPROXIMATELY 50 MILES PER HOUR. THE PLANE ROSE SEVERAL FEET THEN SETTLED INTO THE RIVER AND FLIPPED OVER.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: THE PILOT IN COMMAND'S ATTEMPT TO TAKEOFF WITH INSUFFICIENT AIRSPEED.
