ABSTRACT:
An on-board tail jack assembly (20) for stabilizing the tail region (14) of an aircraft (10) during a loading or unloading procedure is comprised of a jack unit (22) disposed within the tail region of the craft in force communication with a frame member thereof for load transfer and distribution upon stabilizing actuation of the jack, which jack includes a reciprocable jack ram member (36) having a distal end terminating in a coupling member (40); and a strut (24) comprising a shaft (80) having a proximal end terminating in a coupling member (114) with a complementary geometric configuration as respects that of the jack unit for mating engagement therewith, which strut further includes a first shaft member (102) and a second shaft member (104) disposed in biased, adjustably displaceable engagement therewith. The strut is configured for disposition beneath the jack during the loading or unloading procedure in stabilizing contact therewith in order to prevent tipping or rocking motion of the craft in the event its center of gravity shifts aft of the main gear.
