An airplane experienced a left brake failure during the landing roll, causing it to exit the runway right side, strike a ditch, and come to rest inverted on its back.

What happened

The accident occurred while the aircraft was completing its landing roll on an asphalt runway. During this phase of ground operation, the left braking system failed to function. As a result of this mechanical failure, the airplane veered off the right side of the paved surface.

Upon leaving the runway environment, the aircraft struck a ditch. The impact forces caused the nose section to overturn, leading the airplane to come to rest in an inverted position. Throughout this sequence of events, structural separation occurred involving the left main landing gear assembly and its associated brake line.

The investigation

Investigators examined the wreckage and the circumstances surrounding the loss of braking capability. They attempted to determine the root cause of the mechanical failure that led to the departure from the runway. However, the specific reason for the left brake failure could not be determined through the available evidence.
