Probable cause

Pilot in command's failure to maintain an airspeed (angle of attack) that would preclude a stall.

Analysis

The private pilot and his passenger were returning from a local fishing trip and had just taken off from a sand bar near their fishing site. Shortly after becoming airborne, the pilot said that the 'wind stalled the right wing'. He lost control of the airplane and was unable to recover prior to crashing into a lake.
