A large aircraft maintenance hangar in Aksakovo, Bulgaria, houses an aircraft undergoing maintenance

A large aircraft maintenance hangar in Aksakovo, Bulgaria, houses an aircraft undergoing maintenance. The dominant subject is the red and white tail section of an aircraft, featuring a large white star logo on the vertical stabilizer. An access panel on the vertical stabilizer is open, exposing internal structure. Two male technicians are positioned on a blue aerial work platform, working near this section. One wears a light grey shirt and dark pants, while the other is mostly obscured. Adjacent to the aircraft's horizontal stabilizer, two additional male technicians stand on a separate elevated platform. One wears a black hooded jacket with a yellow "ETG" logo, and the other a dark jacket with "PORT-TRAGER" visible. Both appear to be engaged in work on the horizontal stabilizer or adjacent fuselage, where areas are masked or taped. In the background, part of a second aircraft with a blue tail is visible. The hangar features a high ceiling with exposed metal truss work and skylights. The concrete floor, marked with yellow lines, is covered with various maintenance equipment, including rolling carts, pallets of materials, and what appear to be aircraft components. An orange two-tiered utility cart with tools is centrally located on the floor.
