On February 23, 2002, at 1615 eastern standard time, a Cessna 182T, N3533L, sustained substantial damage when it impacted trees after an aborted landing after it had skidded off the end of runway 21 (2,400 feet by 35 feet, dry asphalt) during a full stop landing at the Franklin Flying Field Airport (3FK), Franklin, Indiana. The private pilot was not injured. The 14 CFR Part 91 flight was on a local training flight that originated at 3FK at 1500. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported he had been practicing simulated emergency landings at 3FK. He reported he performed a simulated emergency landing to a full stop on runway 21 at 3FK. On that landing, he applied full brakes and landed on runway 21, but also used about 100 feet of grass beyond the end of the runway to stop. He reported he attempted another simulated emergency landing to runway 21 to a full stop using maximum braking. He reported his airspeed was too high. He reported, "I tried braking but the plane seemed to want to veer toward the right fuel pumps and hangars. Then I decided to engage full power and take off. I was to close to [the] end of the runway #21 and I elected to place plane in brush/trees instead of a head on in ditch/road at end of grass area of #21. About 300 feet. (The airplane almost cleared trees but no such luck.)" The pilot reported there was no mechanical malfunction of the airplane. Witnesses observed the airplane making an approach for landing at a high airspeed and touched down on the runway on the last 1/3 of the runway. The airplane's brakes were locked up and the airplane went off the end of runway 21 and turned 90 degrees before coming to a stop. The airplane taxied back to the approach end of runway 21 and took off. The witness reported the airplane came in for another landing. The airplane's speed was high on final and the airplane landed on the last 1/3 of the runway. Both brakes were locked up and the airplane skidded off the end of the runway. The witnesses reported the airplane turned 90 degrees to the east and full power was added. The airplane got airborne but impacted the trees. The pilot did not have a current biennial flight review. The pilot's medical was valid only for student pilot privileges.
