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 July 26th at approximately 1855 local time during eaa airventure 2018, N677TS was approaching to land runway 33 at the ultralight landing strip on the south end of the wittman regional airport. The aircraft made a normal approach and touchdown according to the pilot and witnesses. On touchdown, the pilot described a snapping sound from the left landing gear. He attempted to keep the broken landing gear off the ground as long as he could by maintaining some extra power on the roll-out. When inevitably the broken landing gear made contact with the ground, the aircraft turned sharply to the left and nosed forward pitching the propeller and damaging the right wing. The aircraft came to a rest on the left side of the runway near the fence. The pilot and passenger exited the airplane with no injuries. Further investigation post-accident, it was discovered that the landing gear brace likely had a crack, which led to the wheel snapping off. This type of crack would have been unidentifiable in the pilot?s normal preflight or routine maintenance inspections.
