## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) PILOT STATED THAT HE WAS LANDING IN RELATIVELY SMOOTH WATER IN LIGHT AND VARIABLE WIND CONDITIONS. JUST AFTER TOUCHDOWN, AIRCRAFT ENCOUNTERED A LARGE ROLLING WAVE THAT THE PILOT HAD NOT NOTICED PRIOR TO LANDING.  THE AIRCRAFT WAS THROWN BACK INTO THE AIR TO A HEIGHT OF APPROXIMATELY 10 FEET.  IT DROPPED BACK ON THE SURFACE OF THE WATER WITH SUFFICIENT FORCE TO CAUSE SUBSTANTIAL DAMAGE TO THE AIRCRAFT.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
