A 30-degree turn left was executed while flying at 50 km NE of Burlington VOR, Boston ARTCC. The aircraft subsequently turned further left and subsequently crashed in mountainous terrain due to spatial disorientation caused by a failure to maintain control after becoming disoriented, exceeding design stress limits in darkness and IMC conditions.A 30-degree turn left was executed while flying at 50 km NE of Burlington VOR, Boston ARTCC.

Description
While cruising at FL160, 50 km NE of Burlington VOR, Boston ARTCC cleared the flight for a 30deg. turn left. The aircraft stabilized and then turned further left. The aircraft broke up and crashed in mountainous terrain. The pilot probably experienced spatial disorientation. PROBABLE CAUSE: “Failure of the first officer (co-pilot) to maintain control of the aircraft after becoming spatially disoriented, and his exceeding the design stress limits of the aircraft. Factors related to the accident were: the lack of two pilots in the cockpit, darkness, and instrument meteorological conditions (IMC) at flight altitude. “
Primary Cause
Failure of the first officer (co-pilot) to maintain control of the aircraft after becoming spatially disoriented, and his exceeding the design stress limits of the aircraft.Failure of the first officer (co-pilot) to maintain control of the aircraft after becoming spatially disoriented, and his exceeding the design stress limits of the aircraft.Share on:
