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 During one flight, the student landed the ASK 21 and had done a fairly good job but was a bit long and were on the roll out and I relaxed a bit. I couldn't see rubber cone (the one we had set out to mark a ground hog hole) in front of us from the back seat. The student tried to avoid the cone by going to the left of it but he didn't get the the glider turned enough to avoid it and the left wing hit it. When I saw what was happening I tried to get the left wing up to avoid hitting it. I was not successful in getting the wing up and we hit the cone. There were black marks on the lead edge of the left wing and black marks on the underside of the wing. When we got back to hangar, we used polish to get all the black marks off the wing successfully. However there are two very small indentations in the underside of the left wing from rolling over the cone.
Other Comments Had I been more vigilant on the landing roll out, we could have just turned slightly right and avoided the cone. The VASI light on the right side of the grass runway 14 probably influenced the student to try turning to the left. What I learned from this is that you can never relax with low time students until the glider completely stops and you are out of the glider.
