Ramp workers' failure to follow procedures was at the root of a low-speed collision last week between two Alaska Airlines jets at a Sea-Tac Airport gate, the airline said Tuesday.
Those two workers, employees of contractor Menzies Aviation, no longer work for the company.
The airline said the driver of a pushback tug lost sight of the wing walker as the tug driver made a sharp turn to correct an error he made in pushing the aircraft away from the gate. He failed to see the wing walker’s signal to stop.
Proper procedure calls for the tug driver to halt his progress if he can’t see the wing walker.
One aircraft’s winglet was replaced that day, and the plane re-entered service. The other aircraft has been repaired and is re-entering Alaska’s active fleet today.
