Investigators recorded the probable cause as: THE PILOT'S FAILURE TO MAINTAIN VREF DURING APPROACH AND HIS IMPROPER FLARE TOUCHDOWN THAT RESULTED IN AN EXCESSIVE PITCH UP ATTITUDE FOLLOWING TOUCHDOWN. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 6 related events involving the same aircraft type or operator are linked below.
During landing, an aircraft's tail struck the runway. The pilot and operator described the approach as normal, but flight data recorder analysis revealed the aircraft decelerated to Vref-8 before touchdown and floated for 8 seconds. After touchdown, the pilot increased pitch attitude to 10.9 degrees, exceeding the manufacturer's limit of 10.5 degrees with landing gear compressed, leading to the tail strike.
