NTSB narrative
The private pilot was landing the airplane on the runway at an ultralight airfield. After the airplane touched down, the left main landing gear (MLG) collapsed at the bottom end of the strut. The airplane ground looped, and the right wingtip struck the ground. The pilot stated that the landing was smooth and gentle, not hard, and that there was no side load on the landing gear at touchdown. He added that he suspected that a previous landing may have been hard, which resulted in a crack in the landing gear.
An examination of the left MLG revealed that the upper/outer strut tubing was broken, and the lower/inner strut tubing was bent. There was no evidence of fatigue. It could not be determined if the crack occurred as a result of the accident or was preexisting.
Probable cause
The failure of the left main landing gear for reasons that could not be determined, which resulted in a loss of directional control during the ground roll.

Source notes (4)
- 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. 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.
