NTSB narrative

The pilot was landing on a grass runway with a slight right quartering tailwind. During the landing, the nose landing gear bounced after touchdown then separated from the airplane. The airplane nosed over and came to rest inverted. The fuselage and empennage sustained substantial damage. Metallurgical examination of the nose landing gear rotation unit revealed the fracture surfaces were consistent with shear overstress. A review of the maintenance logbooks revealed that the nose landing gear had been replaced two previous times due to hard landing events. No anomalies were noted with the airplane that would have precluded normal operation. It is likely that the landing was harder than the pilot perceived, which resulted in the shear overstress of the nose landing gear.

Probable cause

The pilot’s improper landing flare that resulted in a hard, bounced landing and subsequent overstress failure of the nose landing gear.

  • 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, cause areas. 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.
  • API snapshot SHA-256: 662f3d52a96dab4d2c305fe2ac7326635fd1dcd7e963baa2178bf5067391845d; retrieved 2026-09-16T17:38:15.868Z.
  • Corrected after a review of the NTSB narrative, which states these values explicitly: departure. City misspelled with an l for an I; KONZ is Grosse Ile Municipal Airport at Grosse Ile Township, MI.
