The Beriev Be-103 Bekas ( Russian Бериев Бе-103 Бекас ) is an amphibious aircraft made by the Russian manufacturer Beriev . It is a cantilever low- wing aircraft that is rather unusual for seaplanes and floats on the fuselage and wings. The result is a very elegant appearance that can only be recognized as a seaplane at second glance, as the otherwise necessary swimmers could be dispensed with.
history
The first flight took place on July 15, 1997. The first prototype crashed on August 18, 1997 shortly before MAKS 97 . The plane was destroyed and the pilot killed. The second prototype had its maiden flight on September 24, 1998.
During the test, the bow area was changed and the outer wing parts were given fixed slats .

During maneuvering in the water, the structure of the machine is partially in the water and leads to a correspondingly high level of stability. The ground effect is used for take-off and landing in order to keep the speed within tolerable limits, since the aircraft has no landing flaps . Due to the shape of the wings, however, there is a problematic stall behavior . The boat hull has a step . The lake properties are only suitable for calmer inland waters . For use on land, the machine has a retractable nose wheel landing gear. The engines are well protected from the effects of water in the rear part of the machine, well above the waterline. They drive three-blade MT - pitch propellers , which allow a thrust reverser. The cabin can easily be converted from cargo to passenger transport. Both Russian and international technology can be installed as avionics . The installation of a weather radar is also possible.
Beriev expected in 1998 a global demand for such an amphibium of a total of 800 units by 2015. Since a main market was assumed to be in the former Soviet republics, consideration was given to offering an inexpensive variant with a domestic motor especially for this market.
After 300 test flights, approval according to AP-23 and FAR-23 standards was granted in January 2002.
In addition to freight and passenger transport, the intended purpose of use is the flying doctor service, taking aerial photographs, patrol flights , SAR operations and pilot training.
According to information from 2010, an additional eight-seat variant should be developed by 2012.
Besides the Dornier Seastar , the Be-103 is the only twin-engine amphibious aircraft currently in production.
