A business jet may have experienced problems with its stability before encountering turbulence or some other roughness that caused the death of a passenger who served in prominent posts in two presidential administrations, officials said Monday.
The National Transportation Safety Board said it's looking at a “reported trim issue," a reference to adjustments that are made to an airplane’s control surfaces to ensure it is stable and level in flight. The agency initially reported that the plane experienced severe turbulence late Friday afternoon.
