## Probable cause

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.
