De Jakovlev Jak-50 (Russian: Яковлев Як-50) aerobatic aircraft is a single-seat all-metal low-wing monoplane with retractable main wheels and exposed tail wheel. The control surfaces are fabric-covered to save weight. The aircraft is not equipped with flaps. The supercharged engine may be the Vedeneyev M14P (standard production line version), M14PF or M14R, producing between 360 and 450 hp and driving the propeller via a reduction gearbox. The landing gear, brakes and engine starter are operated by compressed air. Replenished by an engine-driven compressor, the main and emergency air bottles are contained within the forward fuselage between the firewall and fuel tanks.

The Yakovlev Yak-50 is a single-seat aerobatic aircraft that was developed by the Soviet manufacturer Yakovlev in the 1970s. It is a low-wing monoplane with a metal fuselage and fabric-covered control surfaces. It has a retractable main landing gear and a fixed tail wheel. The Yak-50 is powered by a radial piston engine that drives a two-bladed propeller. The engine can be either the Vedeneyev M-14P, M-14PF or M-14R, producing between 360 and 450 horsepower.
The Yak-50 was designed as a trainer and aerobatic aircraft for the DOSAAF, the Soviet paramilitary aviation organization. It first flew on 25 June 1975 and entered service in 1976. The Yak-50 proved to be a successful aerobatic aircraft, winning two world championships in 1976 and 1980. It also served as a military trainer for several countries, including Lithuania, Russia and Ukraine.
The Yak-50 has excellent handling characteristics and a high power-to-weight ratio, allowing it to perform complex maneuvers and unlimited aerobatics. However, it also has some drawbacks, such as high fuel consumption, limited range and endurance, and structural fatigue due to the high stresses imposed on the airframe. Some Yak-50s suffered from wing spar failures, resulting in fatal accidents. The Yak-50 was eventually replaced by more advanced aerobatic aircraft, such as the Yak-55 and the Su-26.
Today, only about 90 Yak-50s remain airworthy and are owned by private pilots and collectors in various countries. The Yak-50 is still regarded as one of the best aerobatic aircraft of its era and a classic example of Soviet aviation engineering.
