- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- System/component malfunction/failure (non-power)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The pilot of the airplane reported that, during the landing roll, the airplane was not slowing as expected. The pilot firmly applied braking action with no corresponding slowing action from the airplane. When he and his passenger saw the departure end of the runway approaching, they both applied as much brake pressure as possible without any effect. The airplane departed the runway and came to rest in a ditch, resulting in substantial damage to the engine mount. The airplane’s brake system was inspected by a mechanic who reported that the left side brake functioned, however it had a minor amount of air in the system and may not have had the same working pressure as the right-side brake. The pilot reported that there were no other preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
Loss of brake pressure on the left brake due to air in the brake line which, resulted in a runway over run and collision with a ditch.

- 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: local date, investigation status, coordinates, cause areas. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2022-03-19.
