The Metro was developed by Swearingen on the basis of the Beech Queen Air as a commuterliner, and first flew as the SA-226TC 26 August 1969. The first production version was priced at $743,750 in 1974, less avionics. Twenty were built.

The Metro II SA226-TC of 1975 had minor improvements, larger cabin windows.

The Metro II can convert from a high density 20 seat configuration, to an all cargo configuration in 30 minutes.
