NTSB Report: Private Jet Fatality Caused by Flight Problems, Not Turbulence.

The National Transportation Safety Board (NTSB) has revealed that turbulence was not the cause of a fatal incident on a Bombardier Challenger 300 private jet in March. The NTSB said the pilots turned off a switch that stabilised the plane, causing it to violently buck up and down. The trim system of the aircraft was the subject of a Federal Aviation Administration mandate last year that pilots conduct extra safety checks before flights. The passenger who died was Dana Hyde, who served in government positions during the Clinton and Obama administrations and was counsel for the 9/11 Commission.
