Accident Details
A crew conducted a landing at Buenos Aires-Aeroparque-Jorge Newbury Airport. Following touchdown, the braking procedure was initiated and reverse thrust was activated but failed to deploy. The crew then applied the emergency brakes. The aircraft did not stop within the remaining runway distance, overran the end, and collided with a support vehicle (pickup truck) that was parked outside the safety zone.
Sequence of Events
During the landing roll, the primary braking system and reverse thrust were not effective. The emergency brakes were used but could not bring the aircraft to a halt before it left the runway surface. The collision with the parked pickup caused the aircraft to lose its undercarriage and both wings. All four occupants on board sustained injuries.
Probable Cause
The official findings state that the brakes and reverse thrust systems were unserviceable following a failure of the primary hydraulic system. The auxiliary braking system was also unserviceable. For unknown reasons, the problem has not been identified by the flying crew neither the maintenance personnel.
