A door assembly 40a, particularly for coupling to a cabin 38 of an airport ground support tractor, is provided. Door assembly 40a has a door 46 slidably received in a lower track 42 having a ramp 44 so as to translate in a first direction, typically longitudinally, between a closed position and an open position. Door 46 has a main panel 48 and a lower, closeout panel 50 translatable relative to main panel 48 in a second direction between an extended position and a retracted position; typically, the second direction is substantially normal to the first direction and may be vertical. Ramp 44 applies a retraction force to closeout panel to cause it to translate to the retracted position when door 46 moves from the closed position to the open position. A ground service tractor is also provided.
