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.

The aircraft experienced an "off-field" crash landing due to a sudden gust of wind during the approach phase of the landing. The accident site was about 300 yds. Southwest of the Atmautluak Airport. Pilot stated the fuel load was 20 gals. The pilot stated he was on the "down wind" approach to runway 15 when he thought he was a little high, the wind sock indicated a high wind from the back and the wind sock indicated "no wind" upon he arrival in the area. He applied full power for a left bank and climb, to do a "go-around". While in a "down wind" approach to runway 33, he noticed the airspeed was not responding, he was losing airspeed and altitude. At that moment the wind changed direction and increased. The pilot stated the flaps were at the "full" for "final" landing and he started to "bump" the flap handle to increase airspeed. The flaps were never up all the way. During his turn on to the "base" leg the wind was blowing too hard to get any airspeed, the throttle was at "full" power. The control yoke was pulled back almost all the way, the pilot tried to "float" down, the "stall horn" went off. The resulting "power on" stall resulted in the tail hitting first, then the right wing tip, then the left wing.

As the FAA filed it

THE AIRCRAFT EXPERIENCED AN "OFF-FIELD" CRASH LANDING DUE TO A SUDDEN GUST OF WIND DURING THE APPROACH PHASE OF THE LANDING. THE ACCIDENT SITE WAS ABOUT 300 YDS. SOUTHWEST OF THE ATMAUTLUAK AIRPORT. PILOT STATED THE FUEL LOAD WAS 20 GALS. THE PILOT STATED HE WAS ON THE "DOWN WIND" APPROACH TO RUNWAY 15 WHEN HE THOUGHT HE WAS A LITTLE HIGH, THE WIND SOCK INDICATED A HIGH WIND FROM THE BACK AND THE WIND SOCK INDICATED "NO WIND" UPON HE ARRIVAL IN THE AREA. HE APPLIED FULL POWER FOR A LEFT BANK AND CLIMB, TO DO A "GO-AROUND". WHILE IN A "DOWN WIND" APPROACH TO RUNWAY 33, HE NOTICED THE AIRSPEED WAS NOT RESPONDING, HE WAS LOSING AIRSPEED AND ALTITUDE. AT THAT MOMENT THE WIND CHANGED DIRECTION AND INCREASED. THE PILOT STATED THE FLAPS WERE AT THE "FULL" FOR "FINAL" LANDING AND HE STARTED TO "BUMP" THE FLAP HANDLE TO INCREASE AIRSPEED. THE FLAPS WERE NEVER UP ALL THE WAY. DURING HIS TURN ON TO THE "BASE" LEG THE WIND WAS BLOWING TOO HARD TO GET ANY AIRSPEED, THE THROTTLE WAS AT "FULL" POWER. THE CONTROL YOKE WAS PULLED BACK ALMOST ALL THE WAY, THE PILOT TRIED TO "FLOAT" DOWN, THE "STALL HORN" WENT OFF. THE RESULTING "POWER ON" STALL RESULTED IN THE TAIL HITTING FIRST, THEN THE RIGHT WING TIP, THEN THE LEFT WING.
