NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The local area instructional glider flight departed from the runway with the aid of a tow airplane. At 50 feet agl, the tow pilot observed the glider's spoilers were in a deployed configuration. He signaled (wag the rudder) the pilots to check the spoilers. The glider then moved to the left, causing a strain on the tow rope. The tow pilot said that the glider pilot then terminated the tow about 120 feet agl as the glider was turning back to the runway. Prior to crossing the airport perimeter fence, one of the glider's wings struck a telephone pole. The glider cartwheeled, and came to rest upright on airport property.

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

The inadequate pre-takeoff checks by the flightcrew that failed to detect that the spoilers were deployed during the takeoff and initial climb. Also causal was the inadequate supervision of the flight by the flight instructor.
