Antonov AN2 Biplane History
The Antonov AN2 Russian (Soviet) biplane was introduced in 1947 as a massive slow-flying agricultural and utility single engine biplane. By 2002, when production of the AN2 biplane finally ended, in excess of 18,000 had been produced. Originally designed for the Soviet Ministry of Forestry, the Antonov AN2 biplane featured a totally enclosed cockpit and was of all metal construction. It had the capacity to carry up to 12 passengers, take off in as little as 170m and land in 215m. Notably, the Antonov AN2 features a pneumatic system which operates the aircraft's braking system and also facilitates quick tyre inflation at any location. A fuel pump is also built into the fuselage, so that the Antonov AN2 can be re-fuelled from fuel drums without the requirement for any additional external equipment.

The Antonov AN2 Biplane Crash Survivability
Should this biplane suffer a failure in it's 1,000 hp supercharged 9-cylinder Shvetsov ASh-62 radial engine, the pilot is advised, in the aircraft's handbook, to fully pull back the stick, it will then literally fall out of the sky vertically at a speed of approximately 30mph. The airframe has been designed to absorb this impact sufficiently to enable a reasonable chance of survival for both crew and passengers.

The Antonov AN2 in Military Use
The rugged design and excellent STOL (short take off and landing) capability of the this biplane led to the Soviet armed forces acquiring a significant number of that model, primarily for dropping small numbers of parachutists. During the cold war, NATO forces allocated the aircraft the code name "Colt".

The Antonov AN2 Losses
Due to the large number of these aircraft that have been produced, and the numerous decades of service, there have been hundreds of crashes. However, fatalities average out at less than one person per aircraft totally lost. Many of the deaths have been a result of the location where the aircraft came down, i.e. over water, rather than impact damage.

Various scale models, model kits and plans of this aircraft have been available in the market place.
