Location:Portland, VIC -   Australia
Phase: Landing

Departure airport:AVV/YMAV - Avalon
Destination airport:PTJ/YPOD - Portland
Investigating agency: ATSB
Narrative:
Loss of directional control on landing due to MLG torque link failures.

The runway excursion resulted from failure of the lower torque link attachment lug on the left main landing gearís yoke. This allowed the wheels to rotate through 90į with respect to the direction of aircraft travel and skid, producing a large braking effect on the left side.

The failure...resulted from pre-existing cracks that had progressively grown until the part had insufficient strength to support normal landing loads. The cracks initiated principally from areas of pitting corrosion in the lugís bore and were propagated by cyclic stresses imposed during operation.
