The Soaring Safety Foundation (SSF) is the Training and Safety arm of the Soaring Society of America (SSA). Our mission is to provide instructors and pilots with the tools needed to teach/learn both the stick & rudder skills and the Aeronautical Decision Making skills needed to safely fly a glider. We also provide information and analysis of incident and accident trends in order to develop better training tools.

The Soaring Incident Database is now available to help pilots, safety officers, clubs, and commercial operators develop new programs that can help prevent incidents from becoming major accidents. See more incidents by searching the database or register a new incident.

Incident Description The runway at our field has a 1 deg slope that results in taking off downhill and landing uphill. On this particular afternoon the pilot landed the Twin Astir on the grass runway and stopped after traveling about 70% of the runway length. This required the use of a car and tow-rope to move the glider back to the hanger. After towing the glider across the landing runway, the hard-surface take-off runway and the grass tow-plane landing area the glider arrived at the sloped hard-surface taxiway. The wing walker then maneuvered the glider onto the taxiway and suddenly found the glider rolling downhill towards the car. Fortunately the tow-rope was long enough and the wingtip did not strike the car as the glider swung off the taxiway when the wing walker stopped and the glider rolled off the side of the taxiway.
Other Comments A better briefing on when to disconnect the glider and use the normal no-car ground handling procedure would have prevented this incident
