'''Avia''' is a [[Czechoslovakia|Czech]] [[aircraft]] and [[automotive]] company notable for producing [[biplane]] [[fighter aircraft]], especially the [[Avia B-534|B-534]], and [[truck]]s.
== History ==
The company was founded in 1919 and became part of [[Škoda]] in 1928. During the 1930s the factory became the biggest aircraft producer in [[Czechoslovakia]] and moved to [[Letňany]]. During [[World War II]] Avia produced aircraft for the [[Germany|German]] [[Luftwaffe]]. After the war the company was [[nationalization|nationalized]] and became involved in the automotive industry. It manufactured aircraft up to 1963, then continued to make aircraft engines (producing only [[propeller]]s from 1988) and targeted truck production. The company was split in 1992 into propeller and truck sections, both using the Avia brand.

Before the war the company produced civilian and military aircraft, including the [[Avia BH-21]], [[Avia B-534]] and Avia B-71 ([[Soviet]] [[license]]d [[Tupolev SB]]).
Avia had started building [[Messerschmitt Me 109]]G soon after WWII as the Avia S-99, but soon ran out of the 109's [[Daimler-Benz DB 605]] [[Piston engine|engine]].
Also during the war the Germans set up a number of assembly plants in Czechoslovakia for production of the [[Messerschmitt Me 262]]. After the war the manufacturing infrastructure remained intact, so production could start up again for the new owners.
The first Avia S-92 was assembled at Letňany Research Institute in 1945 with the airframes coming from Avia and the engines from the repair works in Malešice (the Junkers Jumo 004, now called the M-04). The S-92's first flight was on 27 September 1946, with Avia's chief pilot Antonin Kraus in control. That same year on December 10th the CS-92 took to the air for the first time.
Delivery of the first S-92 to the Czech air force was on 6 February 1948. Twelve were made in all, nine S-92 and three CS-92, equipping the 5th Fighter Flight, until they were grounded for use as instructional airframes in 1951.
By the time [[Yugoslavia]] showed interest in buying the S-92, Avia was looking at closing down the production line to make way for new up-to-date aircraft, and when Avia were given a license to make the [[Mikoyan-Gurevich MiG-15|Mig 15]] (they were already making the [[Yakovlev Yak-23|Yak 23]], as the S-101) the S-92 production lines were dismantled.
An Avia S-92 (A-1a) and Avia CS-92 (B-1a) can be seen at the Vojenské Muzeum, Kbely AB.
The [[Avia S-199]] was a fighter aircraft built in Czechoslovakia after World War II using parts and plans left over from Luftwaffe aircraft production that had taken place in the country during the war. While a problematic aircraft, unpopular with its pilots, it achieved fame as the first fighter obtained by the [[Israeli Air Force]] for use during the [[1948 Arab-Israeli War|War of Independence]]. Czechoslovakian pilots nicknamed it ''Mezek'' ("Mule"), whilst in Israel it was known as the ''Messer'' ("knife"; it is a common mistake that it was nicknamed ''Sakeen''; the official name was even different - ''Python'').
The S-199 continued to use the Me 109G airframe, but with none of the original engines available, the engine ([[Junkers Jumo 211]]) and propeller from the [[Heinkel He 111]] bomber were used instead. The result of this compromise was an aircraft with poor handling qualities. The substitute engine lacked the responsiveness of the Daimler-Benz unit, was heavier, and the torque created by the massive paddle-bladed propeller made control difficult. This latter flaw, combined with the 109's narrow-track [[undercarriage]] also made landings and take-offs more hazardous. A final hidden danger lay in the [[Interrupter gear|synchronization gear]] which did not seem to work properly, leading a few Israeli aircraft to shoot off their own propellers.
Later produced Avia B-33 (licensed [[Ilyushin Il-10]]) or Avia 14 (licensed [[Ilyushin Il-14]]), that [[airliner]] version (able to carry 42 passengers) became the largest aircraft ever produced in Czechoslovakia.

==Private Automobiles==
In 1956, Avia made prototypes of a small automobile. It had a single centrally-placed front seat and steering column, two rear seats, a sliding cabin for access, and a rear-mounted 2-cylinder 350cc Jawa [[motorcycle]] engine. The layout was shared with the Moravan car, which was built at Otrokovice.
== Trucks ==
[[Image:Avia.jpg|thumb|right|Saviem based Avia truck]]
Avia truck production started in 1946. The company produced the Škoda 706R line, and from the 1960s, the highly successful Praga V3S (produced until 1988) and S5T. In 1967 the company signed an important license agreement with [[Renault]], which resulted in the production of the French [[Saviem]] 'A' models. The company produced as many as 17,000 trucks per year.
[[Image:Avia d90.jpg|thumb|left| Daewoo Avia D90]]
In 1995 [[Daewoo Motors]] with [[Steyr]] purchased a majority stake of the company. This resulted in the company being known as 'Daewoo Avia' and a significant investment in development of both product and facilities was undertaken.
In 2005 the company was acquired by the financial company [[Odien Capital Partners]], then in 2006 sold to [[India]]n truck manufacturer [[Ashok Leyland]] and began using the Avia brand again (and new logo).
As a truck maker, Czech Avia should not be confused with the [[Avia Vehicles|Spanish Avia]].
