NTSB narrative
The pilot was taking off on runway 21. As he raised the tail for lift off (about 50 mph), the airplane 'abruptly swerved to left (90 degrees), [departed] the runway, crossed a dirt border about 6 feet wide, flipped on its back, and slid down to the bottom of a drainage ditch between the runway and the adjacent taxiway.' The pilot said the airplane was equipped with Goodyear 'expanded tube' brakes, known to lock up if overheated (brakes were used for landing and for taxi to takeoff). An airport mechanic attempted to turn the left main wheel by hand shortly after the accident, and found the wheel to be binding. The right wheel turned freely. Later, he tried again and the wheel turned freely.
Probable cause
Overheating of the left brake, causing the wheel to lock. Factors were the pilot not being able to maintain directional control, a dirt berm, and a drainage 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: 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.
