===Into production===
The zero-series success led to a fall 1964 production order for 70 examples.<ref name="Lindström"/> The first production examples began to arrive in 1967. These demonstrated that the original {{convert|300|hp}} [[Boeing T50]] turbine was underpowered, and a new {{convert|490|hp}} design from [[Caterpillar, Inc.|Caterpillar]] was introduced for the second production batch, the 220 S103B models, which began to arrive in 1970. These engines were retrofit to the earlier examples as well. The production of 290 production models was complete by 1971.<ref name="Lindström"/>
