This led to a batch of four similar aircraft being built for the airline.

After four prototypes were built, production of a small batch of 24 aircraft was launched in 1992.

It was not, however, until February 1917 that the initial batch of 268 aircraft was delivered.

An initial batch of seven aircraft to this standard, sometimes referred to as the F.K.2 were built.

A second batch of 25 aircraft were planned to have been completed by November 1986 as well.

An initial batch of 10 aircraft was ordered for tool verification.

Construction of an initial batch of six aircraft was started immediately.

The service hopes to select a trainer platform and to sign a contract for a batch of 12 to 16 aircraft by 2013.

Despite this, several sources claim that a batch of 12 aircraft to be powered by 12Y-51 engines were ordered.

Initially, a batch of 12 aircraft was ordered, but this was later increased to 60.
