The engine soon began overheating and seized when the airplane was on the base leg of the traffic pattern, forcing the pilot to land short of the runway in loose dirt. The impact crushed the outboard portion of the left wing and buckled the upper skin of the right wing. ## Factual narrative The pilot said the flight was made to test a new cooling modification on the engine.
