Built in 1976 and imported as N104GS by Perimeter for spares use, but it was put into service instead, as here. Later it was repainted in the standard green livery. Still registered in 2023 but believed withdrawn from use, likely having reached its 50,000 hr airframe life limit. (Swearingen would suffix the c/n with a letter 'E' if the aircraft was factory modified from 226AT to 226TC, or vice versa. In this case there are two which were acquired when the original TC (N5319M) was converted to AT (A4O-AI) for the Oman Police, then converted back to TC as N104GS.)
