Pilot error?
‘...an investigation revealed the pilots flipped a switch and disconnected a system used to stabilize the plane.
According to investigators, Dana Hyde died after the plane “turned nose-up at several times the force of gravity.”’
“ The National Transportation Safety Board said the pilots were responding to several warnings in the cockpit of the Bombardier jet that diverted to a Connecticut airport March 3. They followed a checklist and turned off a switch that “trims” or adjusts the stabilizer, a control panel on the plane’s tail.”

Likely not pilot error. They were following the checklist for the situation they were in. In fact it may have been pilot skill to recover from the situation they were in.
