The pilot made one successful landing on the grass. During the next landing, the airplane bounced, which resulted in a nose up attitude. The pilot does not recall if he added engine power to remedy the bounced landing. However, the pilot did not perform a go-around as recommended by the Federal Aviation Administration Airplane Flying Handbook. The airplane stalled and impacted terrain in a nose low attitude. The propeller "dug in" the terrain and the airplane nosed over. The airplane subsequently sustained substantial empennage damage. The pilot indicated that there were no mechanical malfunctions with the airplane. ## Factual narrative The commercial pilot was practicing landings with light wind present in his tailwheel airplane on an occasionally used grass area south of the paved runway.
