G 109

The Grob G 109 is a lightweight, all‑metal training and touring aircraft produced by the German manufacturer Grob Aircraft. First flown in 1978 and entering series production in 1979, the G 109 was designed to replace older piston‑engine trainers such as the Cessna 150, offering modern handling and lower operating costs. Its structure is based on the successful G 109 motor glider, but equipped with a 100‑horsepower Lycoming O‑235 engine, a fixed tricycle landing gear, and a spacious side‑by‑side cockpit with dual controls. Key features include a carbon‑fiber reinforced wing, which provides a high strength‑to‑weight ratio, excellent stall characteristics, and a relatively low stall speed of 39 knots. The aircraft’s simple avionics suite and robust airframe make it suitable for primary flight instruction, aerobatics, and cross‑country trips. Over 500 units have been delivered to flight schools, military aero‑clubs, and private owners across Europe and beyond, establishing the G 109 as a versatile workhorse in general aviation. Its longevity and continued production underscore Grob’s commitment to efficient, low‑cost training platforms, influencing the design of subsequent composite trainers worldwide, and training standards worldwide.
