From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

From subject statement

"Departed 08, announcing on CTAF that I was staying in the pattern. With the relatively light winds, the aircraft climbed very well and I estimated I was more than 100 feet off the ground before passing the first taxiway intersection.

At that moment, I would have normally put the gear up. But since I still had another 2000 feet of usable runway, I opted to leave it down for the moment in case of an engine failure.

I neglected putting it up as a passed the end of the runway.

I made a crosswind turn less than a ¼ mile from the end of the runway, followed by a downwind turn about ¼ mile north of the runway. Mid field, I announced on CTAF that I would be performing a water landing just west of the airport, in the pattern for runway 8. I used the downwind as an inspection pass to check for boats, debris, water conditions (noted as glassy). There was one boat travelling at a high rate of speed westbound next to the airport that was in my identified touchdown zone. I estimated that he would be clear by the time I touched down, and most of his wake would have dissipated.

About ¼ mile north of the james white parkway bridge, I reduced airspeed to less than 80MPH, set flaps and trim for landing and turned base. I announced on CTAF that I was turning base for runway 08 for a water landing west of the airport. I usually do this not only to alert other planes in the pattern, but as a separate check for myself to verify gear position.

Unfortunately, while I think I looked at the gear indicator, for some reason, I did not process that it was green for a runway landing. The landing gear was down and indicated as such and I did not notice. I think I was distracted or lost focus. I know I was watching water conditions / wake and rechecking my landing spot most of the time I was on base.

Turning final, this was my other place to re-verify gear position. Again, I missed it. I know that I re-checked flaps and trim and was concentrating on airspeed and pitch attitude. At that point, I became hyper focused on my landing area and maintaining optimal airspeed for a water touchdown.

As the FAA filed it

FROM SUBJECT STATEMENT

"DEPARTED 08, ANNOUNCING ON CTAF THAT I WAS STAYING IN THE PATTERN. WITH THE RELATIVELY LIGHT WINDS, THE AIRCRAFT CLIMBED VERY WELL AND I ESTIMATED I WAS MORE THAN 100 FEET OFF THE GROUND BEFORE PASSING THE FIRST TAXIWAY INTERSECTION.

AT THAT MOMENT, I WOULD HAVE NORMALLY PUT THE GEAR UP. BUT SINCE I STILL HAD ANOTHER 2000 FEET OF USABLE RUNWAY, I OPTED TO LEAVE IT DOWN FOR THE MOMENT IN CASE OF AN ENGINE FAILURE.

I NEGLECTED PUTTING IT UP AS A PASSED THE END OF THE RUNWAY.

I MADE A CROSSWIND TURN LESS THAN A ¼ MILE FROM THE END OF THE RUNWAY, FOLLOWED BY A DOWNWIND TURN ABOUT ¼ MILE NORTH OF THE RUNWAY. MID FIELD, I ANNOUNCED ON CTAF THAT I WOULD BE PERFORMING A WATER LANDING JUST WEST OF THE AIRPORT, IN THE PATTERN FOR RUNWAY 8. I USED THE DOWNWIND AS AN INSPECTION PASS TO CHECK FOR BOATS, DEBRIS, WATER CONDITIONS (NOTED AS GLASSY). THERE WAS ONE BOAT TRAVELLING AT A HIGH RATE OF SPEED WESTBOUND NEXT TO THE AIRPORT THAT WAS IN MY IDENTIFIED TOUCHDOWN ZONE. I ESTIMATED THAT HE WOULD BE CLEAR BY THE TIME I TOUCHED DOWN, AND MOST OF HIS WAKE WOULD HAVE DISSIPATED.

ABOUT ¼ MILE NORTH OF THE JAMES WHITE PARKWAY BRIDGE, I REDUCED AIRSPEED TO LESS THAN 80MPH, SET FLAPS AND TRIM FOR LANDING AND TURNED BASE. I ANNOUNCED ON CTAF THAT I WAS TURNING BASE FOR RUNWAY 08 FOR A WATER LANDING WEST OF THE AIRPORT. I USUALLY DO THIS NOT ONLY TO ALERT OTHER PLANES IN THE PATTERN, BUT AS A SEPARATE CHECK FOR MYSELF TO VERIFY GEAR POSITION.

UNFORTUNATELY, WHILE I THINK I LOOKED AT THE GEAR INDICATOR, FOR SOME REASON, I DID NOT PROCESS THAT IT WAS GREEN FOR A RUNWAY LANDING. THE LANDING GEAR WAS DOWN AND INDICATED AS SUCH AND I DID NOT NOTICE. I THINK I WAS DISTRACTED OR LOST FOCUS. I KNOW I WAS WATCHING WATER CONDITIONS / WAKE AND RECHECKING MY LANDING SPOT MOST OF THE TIME I WAS ON BASE.

TURNING FINAL, THIS WAS MY OTHER PLACE TO RE-VERIFY GEAR POSITION. AGAIN, I MISSED IT. I KNOW THAT I RE-CHECKED FLAPS AND TRIM AND WAS CONCENTRATING ON AIRSPEED AND PITCH ATTITUDE. AT THAT POINT, I BECAME HYPER FOCUSED ON MY LANDING AREA AND MAINTAINING OPTIMAL AIRSPEED FOR A WATER TOUCHDOWN.
