What happened
On 6 February 2007, a Beech 200C Super King Air, registration VQ-TIU, crashed into a shallow lagoon approximately one nautical mile south-east of North Caicos Airport. The aircraft, operated by Air Turks and Caicoss (2003) Limited, was performing a flight from North Caicos to Grand Turk.
Shortly after takeoff, the aircraft entered an excessive right bank, resulting in a descending, turning flight path. The aircraft struck the water at a relatively high speed. While the impact was severe, the pilot had initiated a recovery attempt just before impact, which reduced the descent rate and kept the aircraft in a nearly level attitude. This action helped preserve the fuselage structure. The accident resulted in one fatality (the pilot) and serious injuries to the five passengers on board.
The investigation
Investigators examined the wreckage and determined that the aircraft was structurally intact and under the pilot's control at the time of impact. Both engines were producing power, and while a minor defect in the right engine's fuel control unit suggested a possible power asymmetry, it was not considered a significant factor in the loss of control. The investigation also reviewed the environmental conditions, which were dark with minimal lighting and no reliable external visual references available immediately after takeoff.
Findings
- The primary cause of the accident was the aircraft adopting an excessive degree of right bank after takeoff, leading to a descending flight path.
- The pilot likely suffered from spatial disorientation, a condition exacerbated by the lack of visual references and the presence of turbulence.
- The pilot's susceptibility to disorientation may have been increased by the consumption of alcohol prior to the flight, as toxicological tests showed a significant blood alcohol level, though below the legal limit.
- The flight was being operated by a single pilot, whereas regulations for this type of operation required a two-pilot crew; a second pilot might have prevented the disorientation from becoming fatal.
- The aircraft was properly maintained, within weight and balance limits, and fully functional at the time of the event.
