NTSB narrative
While transitioning from landing to taxiing the pilot experienced a bumping sound, which was followed by the collapse of the nose gear. Examination of photographs of the damage revealed that several inches of the nose fuselage structure had been ground down by contact with the runway pavement. The nose gear was examined by an airframe and power plant (A&P) mechanic. The mechanic reported that the nose gear drive tube was bent inboard 90 degrees, suggesting that the nose over center adjustment was out of tolerance, and a sufficient impact could cause the gear to unlock from the down position. There was no evidence of mechanical failure or foreign object damage.
Probable cause
The collapse of the nose gear due to an out of tolerance nose gear over center adjustment.

- 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: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2006-04-03.
