We are authorized by Honeywell, Pratt & Whitney, GE, Williams International, and Rolls Royce to perform a broad spectrum of engine services, including MPI, CZI (Overhaul), Hot Section Inspections, unscheduled repairs, and other major maintenance.

Our modern 20,000-square-foot turbine engine facility in Lincoln, Nebraska, features a Honeywell certified 20,000-lb., thrust-class turbofan engine test cell and state-of-the-art control room. The new equipment installed in the NDT and Balance & Flow Rooms has increased our capabilities to support the Honeywell HTF  (AS907) and TFE engines.
