## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Hard landing, landing - flare/touchdown
  - recovery from bounced landing - inadequate, pilot in command (cause)

## Analysis

ACCORDING TO THE PLT, IT WAS A NORMAL FLIGHT AND APPROACH TO RWY 18. ON TOUCHDOWN, THE ACFT NOSE DROPPED AND THE ACFT BOUNCED THREE OF FOUR TIMES. THE PLT STATED THAT HE IMMEDIATELY ADDED PWR AND BECAME AIRBORNE, BUT A VIBRATION CAUSED HIM TO CUT PWR AND LAND THE ACFT. THE VIBRATION WAS CAUSED BY THE ROTATION OF THE NOSE WHEEL.
