NTSB narrative

While maneuvering, the pilot moved the landing gear handle to the "down" position, and received an unsafe indication for the nose landing gear. He then attempted to troubleshoot the system and lower the landing gear manually, but without success. A normal landing was performed to the runway, and the airplane started to roll out on all three landing gear. While decelerating through approximately 40 knots, the nose gear collapsed, the propeller struck the runway, and the airplane slid to a stop on its nose. Examination of the nose landing gear revealed that a downlock actuator pin on the nose landing gear actuator had failed due to fatigue, and worked partially out of its clevis half. The broken pin contacted the actuator arm piston, and prevented the full travel of the nose landing gear to the down and locked position. A manufacturer's service bulletin that addressed the inspection and replacement of the downlock pins had not been completed.

Probable cause

The failure of the landing gear actuator downlock pin due to fatigue, which resulted in the nose landing gear collapsing on landing.

  • 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.
