Undercarriage failure leads to runway excursion (9G-ACL)

Monrovia-James Spriggs Payne, LiberiaLanding (descent or approach)

On June 10, 1978, a Vickers Viscount (registration 9G-ACL) operated by West Africa Air Cargo was involved in an aviation accident near Monrovia-James Spriggs Payne, Liberia during landing or approach. No fatalities were reported. Investigators recorded the probable cause as: The collapse of a landing gear component during touchdown caused the aircraft to veer off the runway. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

An aircraft experienced a landing gear collapse during touchdown, resulting in a runway excursion and significant airframe damage.

What happened

During the landing phase of the flight, the aircraft experienced a structural failure involving one of its undercarriage components. As the plane touched down, the collapsed gear caused the aircraft to lose directional control on the runway surface.

The resulting loss of stability led the aircraft to slide along the runway before veering off the paved surface entirely. The movement continued until the plane came to a final stop in an area of rough terrain adjacent to the runway.

Despite the severity of the excursion, all four crew members were able to evacuate the aircraft without sustaining injuries. However, the impact and subsequent slide resulted in the aircraft being declared a total loss, as it was damaged beyond repair.

Findings

  • The primary sequence of events was initiated by the collapse of one undercarriage unit during the landing roll.

Probable cause

The collapse of a landing gear component during touchdown caused the aircraft to veer off the runway.
