the early rotation of the airplane to an angle at which the fuselage contacted the runway. Contributing to early rotation was the Captain’s reaction to the erroneous V1 automated callout, likely assuming that the airplane was at or close to the correct Vr at the same time. The erroneous automated callout was likely due to a keystroke entry error by the FO when manually entering takeoff data for a newly assigned departure runway.

the flight crews failure to perform a takeoff performance data briefing following the final entries into the Flight Management System, which would have alerted them to the incorrect weight entry and resulting incorrect landing speeds. Contributing to the accident was the failure of the flight crew to recognize and respond to various visual cues indicating the airplane's airspeed was too slow, resulting in a higher than normal pitch during landing and the tail of the airplane striking the runway.

The first officer inadvertently selecting the landing gear handle up after touchdown during the landing rollout. Contributing to the accident was the first officer's decision to reconfigure the airplane while still on the active runway.

The flight crew’s inability to maintain the airplane on the runway centerline after touchdown due to the reduced braking action resulting from the deteriorating weather conditions, which caused the airplane’s departure from the runway surface. Contributing to the accident were the delay in performing the runway assessment for undetermined reasons and failure to close the runway. Also contributing to the accident was the controller’s failure to advise the accident flight crew that braking action was no longer cons…

The flight crewmembers’ failure to properly monitor the airplane’s flightpath, which caused the approach to become unstabilized and resulted in the airplane’s descent below the decision altitude while misaligned with the localizer course. Contributing to the incident were the first officer’s delay in setting go-around thrust after the captain called for the go-around and the captain’s failure to take control of the airplane after go-around thrust was not immediately set, both of which caused the airplane to come wi…
