Since obtaining the engines from Lycoming, Honeywell has invested many millions of dollars into several improvements which have resulted in one for the most efficient turboshaft engines available today. The engine are maintained using an “On Condition” service plan that has drastically reduced over all cost and down time. The use of rotating components with very high hour and cycle limits, no overhaul requirement on the basic engine and an average 6% reduction in fuel consumption, has resulted in the SD version of the popular AS350 series helicopter having the lowest operating cost of any comparable machine.

The installations are in world wide use with separate STC’s being used by FAA, EASA, CAAC China and ANAC Brazil.
