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 he dubbed Excalibur. Then a new fuselage (but with a similar nose) and vertical fin were 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 and then Garrett TPE331 turboprops. These were marketed as business aircraft seating eight to ten passengers. The Metro and Metro II were limited to a maximum weight of 12, 500 pounds (5, 670 kg) in the USA and 5, 700 kg in "metric" countries. When this restriction was lifted the Metro II was re-certified as the Metro IIA in 1980 with a maximum weight of 13, 100 pounds (5, 941 kg) and the Metro II's TPE331-3 engines replaced by -10 engines of increased power. At least one Metro IIA flies in Canada with Perimeter Aviation.[6] In service with Perimeter Aviation in Canada, this long-term operator of the Metro II made a number of modifications to suit its use in northern and remote Canadian sites where rudimentary gravel "strips" were common. Some of the many innovative changes to the design of the Metro allowed the aircraft to fly more efficiently as well as cutting down on the "noise factor" that was attributed to the early models. The airline installed Garrett engines with quieter and more efficient four-bladed Hartzell propellers. Their Metros are also all equipped with modern avionics suites including certified AlliedSignal KLN 90B GPS.
