Duncan Aviation Authorized for Honeywell APU Repairs

Duncan Aviation’s facility in Lincoln, Nebraska, received heavy maintenance authorization from Honeywell Aerospace for the RE100 auxiliary power unit (APU) series. Under the authorization, Duncan Aviation can perform extensive overhauls and complex repairs on RE100LJ, RE100XL, and RE100CS APUs. The series is found on a range of business jets, from the Bombardier Learjet 45/75 to the Cessna Citation Excel/XLS, Sovereign, and Latitude.

The MRO company is integrating in-house RE100 APU overhaul capabilities into its Honeywell engine overhaul shop. Slated to be available in early 2027, the repair and overhaul work will be steered by Duncan Aviation engine program manager Shawn Schmitz. This integration eliminates the need to ship APUs to outside facilities, streamlining maintenance and reducing downtime.

Duncan Aviation is also investing in specialized tooling and infrastructure to accommodate the work, including an upcoming installation of a modular test cell. It said this climate-controlled, soundproof cell incorporates monitoring equipment to ensure each APU meets rigorous performance standards. In addition, 38 Duncan Aviation engine technicians have completed factory-specific training for the RE100 series.

“By bringing this heavy work in-house, we are providing our customers with the same quality and care they have come to expect from Duncan Aviation, while delivering a more seamless, end-to-end service experience,” said Duncan Aviation engine manager Brad Wales.
