NTSB narrative
The pilot was cleared for the option after flying the only available localizer approach through a 1,200-foot overcast. She opted to land straight ahead with a 6-knot tailwind, and landed about 1,500 feet down the 4,500 foot runway. During the rollout, the pilot found she had almost no toe brake pressure, and when she attempted to pump up brake pressure through an emergency handle, there was still no pressure of any significance. The airplane rolled off the end of the runway, and into a brook. Wreckage examination revealed no ruptures of the hydraulic lines, some hydraulic fluid pooled under the rudder pedals, and leaks from both brake cylinders. No brake pressure could be established using the toe brakes, and the emergency hand brake had to be pumped four times before any toe brake pressure developed. Airplane maintenance had been performed three months earlier, which included bleeding the brake system and replenishing the reservoir.
Probable cause
The failure of both the normal and emergency brake systems.

Source notes (4)
- 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.
