Narrative:

Nov/xa/99 at XA30, I was conducting a local VFR training flight in a schweizer sgs 2-33 glider, based at waynesville airport, oh. The WX was clear skies and unrestr ceiling, with light and variable winds favoring the south. My student had 19 flts amounting to 6 hours of training with me. The student flew a nice aeronautical tow and demonstrated proficiency in the basic training maneuvers on and off tow, after which we entered a normal pattern for landing. Turning final we were high and fast. I let the student continue and she began correcting appropriately with spoilers for our glide path. Though she maintained her extra speed, we were on target for our aim point as we entered ground effect. At this point she began full displacement and retraction of the spoilers, perhaps in an attempt to make a 'smooth' landing. I tried to coach her to the proper technique, but only wasted valuable runway. I took control too late for normal stopping techniques, and in an attempt to stop we had to avoid a parked aircraft and eventually struck a railroad tie with the right wingtip doing substantial damage. The spoiler handle in this glider employs a wheel brake on the last few inches of travel. When I first applied full braking, the handle came off in my hand. Then on reapplication, the wheel locked up and we slid on the wet grass to impact. I believe it was poor judgement on my part to wait so late in the landing to take control.

I TOOK CTL TOO LATE FOR NORMAL STOPPING TECHNIQUES, AND IN AN ATTEMPT TO STOP WE HAD TO AVOID A PARKED ACFT AND EVENTUALLY STRUCK A RAILROAD TIE WITH THE R WINGTIP DOING SUBSTANTIAL DAMAGE. THE SPOILER HANDLE IN THIS GLIDER EMPLOYS A WHEEL BRAKE ON THE LAST FEW INCHES OF TRAVEL. WHEN I FIRST APPLIED FULL BRAKING, THE HANDLE CAME OFF IN MY HAND.
