What happened
According to the pilot, the aircraft encountered a critical failure of the braking system during the landing phase. As the plane attempted to decelerate on the runway, the brakes failed to function effectively. Consequently, the aircraft continued its momentum past the end of the paved surface and came to a halt approximately 10 feet beyond the threshold after rolling into a shallow ditch.
The investigation
Maintenance personnel conducted an examination of the right wheel brake system following the incident. Their inspection revealed no evidence of mechanical malfunction or fluid leakage within that specific assembly. However, the left wheel brake sustained damage during the overrun, which prevented a thorough inspection of its condition.
