Abstract
Abstract A landing gear foot pivotally mounted at the lower end of a vehicle landing gear leg. The landing gear foot comprises a body having a curved outer surface, two spaced apart bearing journals having aligned axes, and two gusset plates, each connecting a different one of the bearing journals to the curved body. An aperture is formed through the curved body between the gusset plates. The landing gear foot is pivotally connected to the landing gear leg proximate the free end thereof by means of the bearing journals and appropriate shafts.
