FIELD: aeronautical engineering; flying vehicle undercarriages. SUBSTANCE: door consists of main smaller doors. Main door is rigidly secured to undercarriage leg. Smaller door consists of two panels interconnected coaxially which are movable relative to guides of this door, thus providing for reliable operation of door. Smaller door is movable during motion of under-carriage leg.
