NTSB narrative
The pilot departed from a meadow in the Arctic Aircraft S-1B2 "Arctic Tern," and after some local sightseeing returned for landing. He reported that just after touchdown he heard a "pop" and the landing gear collapsed. An FAA Inspector, who interviewed the pilot, reported that the pilot stated that upon touchdown the left main landing gear collapsed, the aircraft began skidding and then the right main landing gear collapsed. The aircraft then nosed over and came to a stop. The pilot reported that the landing site was a flat, dirt field. Metallurgical examination of the left landing gear attach fitting revealed fracture features and deformation typical of an overstress fracture under a combined torsion and bending load. There was no evidence of a pre-existing cracking condition at the fitting's separation surfaces.
Probable cause
The pilot's improper flare.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
