Engine parts undergo inspections to identify out-of-tolerance conditions.

The new overhaul center includes dedicated OEM sinks, chemicals and processes.

Dye penetrant, eddy current, magnetic particle and ultrasonic inspection detect cracks and subsurface defects.

Duncan Aviation’s existing 20,000-lb.-thrust test cell used for Honeywell TFE731 engines, which became operational in 2017, “is running all the time,” so it wanted to build a new 20,000-lb.-thrust Atec test facility to support the PW300 and PW500 engines, says Scott Stoki, VP of engine operations. 

Duncan Aviation also is a Honeywell TFE731 authorized overhaul shop. It employs 65 team members in 3 shifts.

Duncan Aviation has been performing authorized repairs on Honeywell HTF7000 since 2015, including 4,800-hour borescope inspections.

Earlier this year Honeywell authorized Duncan Aviation to perform RE100 APU heavy maintenance—the capability of which Duncan expects to come online in 2027.

The new engine center includes a parts warehouse that includes 4,362 lines of inventory. 

Duncan Aviation’s technical education center supports its 20-month AMT apprenticeship program that started in 2020. Two cohorts start annually. The center also is used for onboarding new hires and supports DME testing for new FAA mechanics.
