Beech 58 accident near St. Croix, December 8, 2017

On December 8, 2017 at about 1:00 am local time, a 1970 Beech 58, registered N4494A, was destroyed in an accident during approach near St. Croix (Henry E Rohlsen airport). It was a personal flight under general aviation rules (Part 91). 5 people were killed. The weather was visual conditions (good weather).

The NTSB's probable cause their words, unchanged

The non-multiengine rated pilot's failure to maintain airplane control during a single-engine approach. Contributing to the accident was a total loss of engine power on the left engine due to detonation for reasons that could not be determined based on the available information.

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

Before departing on the night cross-country flight in the multi-engine airplane with four passengers, the private pilot, who did not hold a multi-engine rating, called a flight instructor/mechanic, because he was having problems starting the left engine. The flight instructor/mechanic advised the pilot to wait until the next day; however, the pilot chose to depart. Shortly after takeoff, the pilot advised air traffic control that the engines were "not running right" and that he needed to return to the airport. The airplane was cleared to land, but impacted terrain about 500 ft short of the runway threshold and was destroyed by impact forces and a postcrash fire. The disposition of the wreckage suggested a steep descent and impact attitude with little horizontal motion, consistent with a loss of control. Examination of the left engine found that the No. 2 cylinder piston exhibited severe detonation damage, which likely resulted in the subsequent catastrophic failure of the left engine; however, the reason for the detonation could not be determined. While the pilot lacked a multiengine rating, the investigation was unable to determine his prior multiengine flight experience.
