Human Factors
Coming in on the last landing of the night after doing pattern work; we were working on power off 180 and short field techniques; after about 6 patterns we decided to make the last one a full stop and practice our crosswind technique. In the pattern I briefed [the student] that I would take controls when we were close to the runway environment to show her a float using ground effect if she needed to use it in an event of a power off landing. We were on final and crossed the runway threshold when I took over controls we were approximately 50-75 feet when we crossed the numbers; I then started to correct for the crosswind adding right rudder and left aileron as I got closer to the ground. I started pitching up in the flare to demonstrate a controlled stall over the runway using ground effect to my advantage; suddenly I found myself in a higher than normal pitch attitude which cause me to stall slightly higher than anticipated; this caused my right wing to fall suddenly and this is what made it make contact with the runway. It was a hard landing but I thought I had landed on the mains; it wasn't until we came to a complete stop on taxiway alpha that I saw the right rear wing tip had been bent up slightly. We were then told to taxi back to the ramp by tower; I was checking controls and they seemed operational. I did a closer inspection of the tip and found contact marks on outer mid tip as well as the rear tip. I believed I misjudged the actual height above the runway which caused me to stall and let the wing drop.
A flight instructor reported that while working on power off 180 and short field techniques in a Beechcraft BE-33; the pilot found himself in a higher than normal pitch attitude which caused the plane to stall; resulting in the wingtip contacting the runway.
