Analysis

During cruise flight the engine of this homebuilt aircraft began running rough. The pilot turned toward an airfield approximately 15 miles away, but was forced to perform a forced landing about 5 miles short of this field because, following a loud metallic bang, the engine stopped. A restart was impossible because the aircraft does not have a starter. An engine examination following the accident revealed a loose oil filler cap (with 1 qt of oil remaining in the engine) and nothing else unusual. The engine could not be test run due to impact damage. The aircraft collided with a steel storage tank during landing.
