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.

(-23) Aircraft lost power just after takeoff from small lake, immediate turn to avoid cabin and trees on lakeshore. Aircraft landed hard on the water near the shoreline. Takeoff run included a prolonged step turn (turning while in high speed taxi "on the step") to the left "around a small island" with right fuel tank selected. Weather conditions at time included warm temperatures and high humidity, conducive to carburetor icing. A pilot of another floatplane operating from a nearby lake reported the necessity of "nearly continuous" use of carburetor heat to prevent carburetor ice. Minor damage to aircraft included breaking the left float attach brace. During post incident investigation, airplane engine started and ran with no problems. Lake from which operation was conducted was very small, necessitating step turn takeoff run.

As the FAA filed it

(-23) AIRCRAFT LOST POWER JUST AFTER TAKEOFF FROM SMALL LAKE, IMMEDIATE TURN TO AVOID CABIN AND TREES ON LAKESHORE. AIRCRAFT LANDED HARD ON THE WATER NEAR THE SHORELINE. TAKEOFF RUN INCLUDED A PROLONGED STEP TURN (TURNING WHILE IN HIGH SPEED TAXI "ON THE STEP") TO THE LEFT "AROUND A SMALL ISLAND" WITH RIGHT FUEL TANK SELECTED. WEATHER CONDITIONS AT TIME INCLUDED WARM TEMPERATURES AND HIGH HUMIDITY, CONDUCIVE TO CARBURETOR ICING. A PILOT OF ANOTHER FLOATPLANE OPERATING FROM A NEARBY LAKE REPORTED THE NECESSITY OF "NEARLY CONTINUOUS" USE OF CARBURETOR HEAT TO PREVENT CARBURETOR ICE. MINOR DAMAGE TO AIRCRAFT INCLUDED BREAKING THE LEFT FLOAT ATTACH BRACE. DURING POST INCIDENT INVESTIGATION, AIRPLANE ENGINE STARTED AND RAN WITH NO PROBLEMS. LAKE FROM WHICH OPERATION WAS CONDUCTED WAS VERY SMALL, NECESSITATING STEP TURN TAKEOFF RUN.
