NTSB narrative
The pilot reported that, after a normal approach and touchdown, he applied the brakes and thrust reversers. He stated that as the aircraft slowed to 60 to 70 knots, it veered to the right and exited the side of the runway. The pilot regained directional control after the aircraft exited the runway. Before the aircraft came to a stop, the right wing collided with the VASI lights for the opposite runway. Skid marks leading to the exit point on the runway, indicated that the right-side tire marks displayed heavier braking action than on the left side. Post-accident testing performed on the anti-skid generators revealed that the left-side inboard and outboard generators failed the manufacturer's specifications. The right-side inboard and outboard generators passed all manufacturers specifications. The left-side generators were disassembled. The inspection did not reveal any anomalies. A slight difference in the brush wear between the brush fittings was noted between the two generators. A short circuit between two adjacent collectors was found in the outboard generator rotor fitting. The manufacturer's representative reported that the short circuit was not due to a failure within a cell of the rotor, but was likely due to contamination present between the two collectors.
Probable cause
Partial failure of the anti-skid brake system due to contamination.

- 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.
