NTSB narrative
The pilot reported a failure of the left brake during the landing roll. The airplane departed the runway surface and impacted a fence, which cause substantial damage to the empennage, right elevator, and horizontal stabilizers. Postaccident examination of the brake system revealed that the left brake master cylinder reservoir was completely empty. It was serviced and tested with no failure or leaks identified. Further examination of the brake system included the removal of the main landing gear pivot trunnion. It revealed that the O-rings, while not visibly damaged, were flat and stiff, which likely allowed the brake fluid to leak out from the main landing gear trunnion to the actuator interface joint when the landing gear was retracted.
Probable cause
Failure of the brake system O-rings on the left landing gear trunnion, which allowed the hydraulic fluid to drain from the left brake system, resulting in a runway excursion and impact with a fence.

- 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, 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.
