On November 20, 1999, about 1630 Eastern Standard Time, a Schweizer SGS-2-33A, N17883, was substantially damaged while landing at the Red Stuart Airport, Waynesville, Ohio. The certificated fight instructor and student pilot were not injured. Visual meteorological conditions prevailed and no flight plan was filed for the instructional flight conducted under 14 CFR Part 91. According to the flight instructor, the student pilot was performing a landing to Runway 8, a 2,442 foot long grass runway. As the glider neared the ground, it began to float past the intended touchdown point. The flight instructor suggested to the student pilot corrective actions, but did not receive any response. The flight instructor took control of the glider and immediately set the glider onto the runway. Full spoilers and wheel brake were applied, and the nose of the glider was pushed forward. As the spoilers were applied, the lever handle came off in the flight instructor's hand. The flight instructor dropped the lever back down, reapplying the spoilers and wheel brake again. The wheel brake then became locked and the glider began to slide on the wet grass. At the end of the runway, the flight instructor attempted to "ground loop" the glider to avoid impacting a parked glider, and stuck a railroad tie with the right wing. The flight instructor additionally stated that he did not react in time to regain control of the glider after the student landed long. The winds reported by a facility 17 miles to the southeast were from 200 degrees at 5 knots.
