The NTSB's narrative final · quoted from the NTSB record

The pilot of the 1918-vintage former military fighter airplane reported that during a flight in the airport traffic pattern the engine lost power on the downwind leg. The engine briefly regained power, which allowed the pilot to quickly turn onto the base leg and then onto final approach, but the engine lost power again. The airplane landed hard on the runway, fractured the main landing gear, and nosed over. The postaccident engine examination did not reveal evidence of any preimpact mechanical malfunctions or failures. The reason for the loss of engine power could not be determined based on available information.
