Duncan Wraps First TFE731 Core Zone Inspection
The Lincoln, Nebraska MRO recently completed its first core zone inspection on a Honeywell TFE731 and is gearing up for more.

Duncan Aviation has completed its first in-house core zone inspection (CZI) on a Honeywell TFE731 at its turbine engine overhaul facility in Lincoln, Nebraska. “The CZI process is not new to us," Mike Bernholtz, the company’s turbine engine service sales representative, told AIN. “We have done hot section inspections and partnered with the OEM on arranging core inspections for decades.”
