<h1>Fuel cutoff to both engines caused rapid loss of thrust, prompting scrutiny of crew actions and emergency system response.</h1> Both engines' fuel cutoff switches moved from RUN to CUTOFF within one second after liftoff, causing rapid loss of engine speed and thrust; pilots were confused about who actuated the cutoffs and, despite returning switches to RUN and deploying the Ram Air Turbine, only one engine showed recovery. A mayday was issued and flight data recording stopped, facts that focus regulatory review on crew coordination, emergency system performance, relight procedures, and data capture during the critical climb phase.
