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.

On November 18, 2023, the pilot of an experimental PA-18 type home-built Kase Kub took off from wolf lake strip (4AK6) after a condition inspection. The aircraft headed to wasilla airport (paws), where two stop-and-go landings were performed. The pilot then flew to Big Lake Airport (pagq) and attempted a landing without checking the automated weather reporting. The pilot was uncertain about the snow's depth, estimating it to be shallow due to the light covering observed and reported at other nearby airports, which were also hard-packed. Upon touchdown, the aircraft's wheels sank into the deep snow-covered runway, causing it to flip nose over. The rudder, vertical stabilizer, empennage, and propeller were all damaged. The pilot was counseled on proper airport planning along with checking weather and runway conditions before attempting landings.

As the FAA filed it

ON NOVEMBER 18, 2023, THE PILOT OF AN EXPERIMENTAL PA-18 TYPE HOME-BUILT KASE KUB TOOK OFF FROM WOLF LAKE STRIP (4AK6) AFTER A CONDITION INSPECTION. THE AIRCRAFT HEADED TO WASILLA AIRPORT (PAWS), WHERE TWO STOP-AND-GO LANDINGS WERE PERFORMED. THE PILOT THEN FLEW TO BIG LAKE AIRPORT (PAGQ) AND ATTEMPTED A LANDING WITHOUT CHECKING THE AUTOMATED WEATHER REPORTING. THE PILOT WAS UNCERTAIN ABOUT THE SNOW'S DEPTH, ESTIMATING IT TO BE SHALLOW DUE TO THE LIGHT COVERING OBSERVED AND REPORTED AT OTHER NEARBY AIRPORTS, WHICH WERE ALSO HARD-PACKED. UPON TOUCHDOWN, THE AIRCRAFT'S WHEELS SANK INTO THE DEEP SNOW-COVERED RUNWAY, CAUSING IT TO FLIP NOSE OVER. THE RUDDER, VERTICAL STABILIZER, EMPENNAGE, AND PROPELLER WERE ALL DAMAGED. THE PILOT WAS COUNSELED ON PROPER AIRPORT PLANNING ALONG WITH CHECKING WEATHER AND RUNWAY CONDITIONS BEFORE ATTEMPTING LANDINGS.
