The NTSB called upon federal regulators to create a review process before allowing automated test vehicles to operate on public roads, based upon the agency’s investigation of a fatal collision between an Uber automated test vehicle and a pedestrian.

The NTSB determined during a public board meeting that a fractured fan blade from a CFM International CFM-56-7B engine, powering a Southwest Airlines Boeing 737-700, led to the engine inlet and fan cowl separating and subsequently damaging the fuselage, resulting in a rapid cabin depressurization.

The National Transportation Safety Board issued Hazardous Materials Incident Report 19/02, following its investigation of the Feb. 11, 2018, release of compressed hydrogen and subsequent fire in Diamond Bar, California.
