Primary finding
Probable cause
The glider pilot’s loss of visual references during the landing approach resulting in an off-airport landing on rough sloping terrain.
Investigator assessment
Analysis narrative
The glider pilot reported that during base leg to final approach for landing, he lost sight of the runway, forcing him having to maneuver to avoid a house and to perform an off-field landing on rough sloping terrain. The glider impacted the ground hard, ground-looped, and came to rest in a large ditch. The glider sustained substantial damage to the fuselage, vertical stabilizer, rudder, and left wing. The pilot reported there were no preaccident mechanical failures or malfunctions with the glider that would have precluded normal operation. The pilot also reported that this was his first landing at this airport and that he should have flown an orientation flight with another pilot familiar with the airport.
