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 1.) 5th Oct 2024 a SGS 2-33 had an uneventful takeoff for the first O-Flt of the day. 2.) On pattern entry and approach to landing the spoilers stuck open and the IP had to make an off-field landing. 3.) The off field landing was accomplished without injury or damage to the glider. Per CAPR 160-2 5.1.5.2 any off airport landing irrespective of cause is designated a near miss. 4.) The screw that secures the top left side of the rear pilot’s backrest and anchors the brace to the spoiler bellcrank was missing. The resulting play in the spoiler system caused the spoilers to lock open. The rivet nut securing the screw appears to have broken free.
Other Comments Add to preflight checklist a feel at the back of the bolt to make sure it was still retained correctly. Another experienced instructor advised that this had occurred to him in the past. There is a powerpoint that has drawings / photos diagrams etc.
