(-23) On June 6, 2003, at approximately 1600 hours CDT, N8246J, a rotorway executive 90 experimental helicopter, was involved in an accident. It was discovered that while in cruise flight, the pilot in command experienced an engine power decrease. The trouble was an overheating engine. The pilot in command executed an emergency landing and upon power decrease, the engine faltered then failed. An autorotation was entered and at ground contact, the aircraft pivoted to the right. With the energy still directed in the original tract and upon ground contact with the left skid, a rolling motion was produced. The aircraft rolled to the left coming to rest on the left side.
