Smyrna Air Completes First King Air Power 90 Upgrade
GE Aviation’s M601E-11A engines are now powering Anchorage, Alaska-based AeroMetric’s King Air E-90. The upgrade is the first done by Smyrna Air Center of Smyrna, Tenn. The Power 90 program is designed for King Air 90 aircraft and replaces the installed engines with 705-shp M601E-11A engines. “We’ve received feedback from AeroMetric’s pilot that GE M601 engine operating temperatures are lower than previous engines and that time to climb is 30 percent less, which is critical for them since the airplane must reach altitude before aerial mapping can begin,” said Smyrna Air Center president Bob Fields. In addition to faster rates of climb, the M601E-11A engine is reported to also provide faster cruise speeds, according to a July 2010 study by Conklin & de Decker performed for GE. The more than 1,600 M601 engines in service have accumulated a combined 17 million flight hours.
