GE Aviation has named the Power 90 as a GE Preferred Engine Conversion for the King Air 90 aircraft. Additionally, Smyrna Air Center has been named a GE Designated Engine Installer for the Walter M601E engine on King Air 90 aircraft. Smyrna Air Center of Smyrna, Tennessee, holds the rights to the Power 90 conversion STC.
The STC, for King Air 90, A90, B90 and C90 aircraft, replaces the original engines with the 751 shaft-horsepower (shp) Walter M601E-11A engines. The E-11A engine delivers faster rates of climb, higher flight levels, faster cruise speed and lower maintenance costs, according to GE Aviation officials. To date, more than a dozen King Airs have been converted to M601E-11A engine power.
Based at the Smyrna/Rutherford County Airport (MQY) near Nashville, Smyrna Air Center has a factory authorized maintenance and avionics center specializing in corporate and general aviation. The FBO also offers 54 T-hangars in addition to a 38,000-square-foot common hangar that is both heated and air-conditioned. The FBO facility has conference rooms, wireless Internet, pilot lounges, 2,500 square feet of office space and a Part 145 Repair Station.
