NTSB narrative
The pilot reported that during the landing roll he applied the brakes, the airplane made a left turn, exited the left side of the runway, and impacted a hangar. A post-accident examination of the airplane by Federal Aviation Administration Air Safety Inspectors identified a failure of the airplane's master brake cylinder, revealing the master cylinder was leaking hydraulic fluid and no fluid was found in the brake system's reservoir. The airplane sustained substantial damage to the left wing.
The pilot reported there were no mechanical malfunctions or failures with the airplane prior to or during flight that would have precluded normal operation.
Probable cause
The failure of the brake master cylinder which resulted in a loss of brake pressure and the subsequent loss of 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.
