Aircraft Accident/Incident Report

Picayune, Mississippi 39466
Sunday, September 17, 1995 15:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot-in-command stated he obtained a weather briefing before departing on the flight and was advised of thunderstorms in the area. While airborne he observed the thunderstorm and thought it had matured and was dissipating. A short time later the thunderstorm developed and started moving towards his destination airport. He decided to make an approach to the airport, but had to abandon the approach due to the thunderstorm. He maneuvered the glider for an approach to a football field when the glider encountered a gust of wind and collided with trees and the roof of a house.

NTSB Probable Cause Narrative

The pilot-in-command's disregard of a weather forecast and flight into known adverse weather condition (thunderstorm). The thunderstorm, and associated wind gusts, were factors.
