NTSB narrative
In preparation for landing, the pilot lowered the landing gear and noticed the right landing gear light was not illuminated. After repeated unsuccessful attempts to lower the landing gear, he manually extended it and it appeared down and locked. The pilot then confirmed with ground personnel that all three landing gear appeared to be extended. During touchdown, the right main landing gear collapsed and the airplane swerved to the right and traveled off the side of the runway. Examination of the landing gear system revealed the right main landing gear downlock actuator spring was distorted.
Probable cause
The failure of the right main landing gear actuator downlock spring.

- 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.
