NTSB narrative
Soon after touching down on the main landing gear, the airplane's left brake locked up, and the airplane began to veer toward the edge of the runway. During the pilot's attempts to keep the airplane rolling straight, both bottom wings came in contact with the runway surface, and the airplane nosed over. The airplane's left tire had created a significant skid mark starting just past where the airplane touched down. There was no evidence of skidding of the right main landing gear tire. The investigation did not reveal any reason for the malfunction of the left brake, but the skid mark on the runway indicated that the brake mechanism had malfunctioned or locked up while the airplane was in the air, or during the touchdown sequence.
Probable cause
The locking/seizing of a main landing gear brake mechanism during the landing roll.

- 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.
