A-25 composite flying boat was created in Samara by Aeroprakt design bureau (successors of famous designer Almurzin). Mid-wing aircraft with powerful 6-cylinder engine is a high-speed aircraft. First flight took place on November 11, 1994. Hull shape and
wheel retraction mechanics were improved during trials.

A-25 is built for use on unprepared runways, lakes and rivers. It can perform takeoff and landing on waves up to 0.5m. Aircraft can be used in rural areas without developed airfields for different purposes:
The airplane has a comfortable cabin designed by the specialists of VAZ car factory and variable step propeller. Cockpit equipment allows visual flights in daytime, under good weather conditions.

A-25 is built to fulfill the FAR-23 (AP-23) requirements. Aircraft was included into Federal Programm of General Aviation development until 2000. Budget financing of project was promised, but the outcome was a disaster. 'Aeroprakt' received nothing from
the budget, and large sums were already invested into A-25 were virtually frozen. Nonetheless, development continued at low pace. A-25 received new engine with variable pitch propeller. This variant is entering international market under designation
A-25M.
