NTSB narrative
The airline transport pilot reported that during the landing roll on the grass/dirt runway after a cross-country flight, he applied the wheel brakes, and the airplane immediately veered to the left. Despite the application of brakes and rudder control, the pilot was unable to regain directional control as the airplane travelled off the left side of the runway, over a water sprinkler system, and through a fence before coming to rest.
The pilot reported that the left brake line had been breached during the accident sequence. The line was replaced, and testing of the left brake revealed no anomalies that would have precluded normal operation.
Postaccident examination of the airport's runway found it to be in good condition with no holes or defects that would prevent a normal landing. Thus, it is likely that the pilot failed to maintain directional control during the landing roll.
Probable cause
The pilot's failure to maintain directional control during the landing roll.

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, 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.
