NTSB releases findings on fatal private jet incidents.

The National Transportation Safety Board (NTSB) has reported that a passenger on a business jet was fatally injured in early March when the aircraft violently bucked up and down after pilots disconnected a system used to stabilize the plane. The trim system of the Bombardier Challenger 300 twin-engine jet was the subject of a Federal Aviation Administration last year mandate that pilots conduct extra safety checks before flights. The two pilots and three passengers were traveling from Keene, New Hampshire, to Leesburg, Virginia, before diverting to Bradley International Airport in Connecticut.
