This case involves a Hawaiian franchise tour company with a variety of amphibious ‘duck boat’ tour vehicles. On the day of the incident, the tour operator was attempting to cross the road when the axial component of the vehicle failed, preventing it from stopping. The vehicle collided with a building causing 4 passenger deaths and many other injuries. The parent company supplied the vehicle in question to the franchise after refurbishing it for use. It was later discovered that the vehicle’s axial component had been insufficiently repaired by the parent company before the vehicle had been acquired by the tour company. The owners of the franchise location were aware of the faulty axial but had not contacted the parent company or taken additional measures to remedy the issue. An expert in automotive manufacturing was sought to opine on how prudent manufacturers comply with government regulations and vehicle testing prior to putting vehicles on the road.
