At 1742 Central time, the airplane sustained substantial damage after a forced landing to a field resulting from total loss of engine power. The airline transport pilot and two passengers sustained minor injuries; two passengers were seriously injured. An IFR flight plan was in effect although visual conditions prevailed.
According to the pilot, when the airplane was 20 miles from the destination airport, a descent was begun by reducing power. Shortly, the pilot noticed the engine was not responding and he initiated emergency procedures, including switching fuel tanks. The pilot landed with full flaps and extended landing gear on rugged and uneven terrain. Before it came to a stop, the nose gear broke off and the airplane flipped over onto its back. All five people were able to egress the airplane and there was no fire. The pilot did not observe any fuel leaking from anywhere on the airplane after the accident.
