The airplane, operated as an instructional flight, overran runway 22 during an aborted touch and go takeoff. According to the certified flight instructor (CFI), the private pilot was attempting to perform a short field landing. The CFI stated that the pilot misjudged the flare, causing the airplane to balloon. Power was then added, and a landing was made.
After landing, the private pilot retracted the flaps and added power. The CFI described the power addition as slower than normal and occurring beyond the halfway point of the runway, with approximately 1,200 feet of runway remaining. Once full power was established, the CFI reportedly commented to the private pilot on the length of time it took to add power. The private pilot then closed the throttle.
The CFI stated that prior to the power reduction, they had enough runway remaining to complete the takeoff. The airplane overran the runway.
