NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

During the takeoff roll in a 30 degree crosswind of about 12 knots, the aircraft passed on the leeward side of a number of hangars of varying size. As the aircraft passed through the area where the wind was blocked by the individual hangars into areas where the wind was not blocked, the student pilot failed to adequately compensate for the resultant change in wind velocity and direction. As the student pilot continued the takeoff, the aircraft departed the side of the runway, impacted a taxiway exit sign, and entered into an area of wet, soft ground. The student pilot then pulled the power to idle and applied "full brakes." The nose gear then dug into the terrain and ultimately collapsed. There were no anomalies found in the rudder or nose wheel steering systems.

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

The student pilot's failure to adequately correct for changing wind conditions, leading to a loss of directional control during the takeoff ground roll. Factors include wet, soft terrain along the side of the runway.
