Analysis

According to the pilot, the accident flight was the second flight of the day towing banners in his bi-plane. On the return leg, the engine lost all power and the pilot landed along a pipeline and impacted a post, which resulted in substantial damage to the upper and lower right wing. The pilot informed a Federal Aviation Administration inspector that he may have run out of gas. The inspector drained about 1 quart of fuel from the gascolator and "less than a tablespoon" from the sump drains. There was no evidence of fuel in the fuel tanks. The tanks were not breached and the fuel lines appeared to be intact with no evidence of fuel leaks.
