N35589

The solo private pilot was practicing touch and go landings at a private airstrip under Title 14, CFR Part 91. The pilot reported that after touching down long on the runway, he applied full power, and the engine "coughed," and did not produce takeoff power. He said he was approaching the end of the runway and applied too much brake, and the airplane nosed over. He said previously the engine had been running rich at idle. He also reported that he could have cleared the engine on final. He said his instructor who was watching, told him when he applied power a cloud of black smoke emitted from the engine. He said the right wing, right lift-strut, and rudder were substantially damaged in the accident.
