Causes of the crashes included turning conflicts at intersections, and speeding drivers crossing the centerline to use the oncoming lanes as a passing lane.
A notable feature of the landing gear was the ability to pivot the main landing gear up to 20 from the aircraft centerline to increase safety during crosswind landings.
The bearing lining is undercut on the horizontal centerline (the rebore) so that oil entering the bearing is drawn in by the rotation and eccentricity of the journal.
