Fairchild Swearingen Metroliner

The Fairchild Swearingen Metroliner or the Fairchild Aerospace Metro is a 19-seat, pressurised, twin-turboprop airliner first produced by Swearingen Aircraft and later by Fairchild at a plant in San Antonio, Texas, United States.

Design and development

The Metroliner was an evolution of the Swearingen Merlin turboprop-powered business aircraft. Ed Swearingen, a Texas fixed base operator (FBO), started the developments that led to the Metro through gradual modifications to the Beechcraft Twin Bonanza and Queen Air business aircraft, aircraft which he dubbed Excalibur.

A new fuselage (but with a similar nose) and vertical fin were then developed, married to salvaged and rebuilt (wet) Queen Air wings and horizontal tails, and Twin Bonanza landing gear; this became the SA26 Merlin, more-or-less a pressurized Excalibur. Through successive models (the SA26-T Merlin IIA and SA26-AT Merlin IIB) the engines were changed to Pratt & Whitney Canada PT6, then Garrett TPE331 turboprops. These were marketed as business aircraft seating eight to ten passengers.
