The image displays an aircraft engine undergoing maintenance within an industrial hangar facility in Aksakovo, Bulgaria. The primary subject is a large, white turbofan engine, visible from its underside and front, with its nacelle partially open to expose internal components, including wiring, pipes, and machinery. The engine's intake cowl is prominent on the right, featuring a metallic interior surface. Red markings and the text "NO GRAE" (possibly "NO GRAB") are present on the white nacelle. A small, yellow mobile lift is positioned directly beneath the engine. To the left, a section of the aircraft's white wing and a main landing gear wheel are visible. The hangar environment includes a light-colored concrete floor with a yellow demarcation line in the foreground and a square gridded drain cover. The overhead structure consists of a grey and blue metal truss system, supporting industrial lighting. In the background to the right, three individuals are present. They are wearing dark work uniforms, some with visible reflective or colored strips on their trousers, and one has a "Δ ETG" logo on their back. They are standing near the engine, seemingly observing or involved in the maintenance process. Behind them, storage racks with stacked items and a partial "Cargo" sign are visible. Red-framed carts and additional maintenance stands are situated around the engine.
