The Dublin Aerospace APU Service Centre at Dublin Airport provides world-class overhaul, repair and modification services for auxiliary power units (APU). Our state-of-the-art facility includes a test cell which accommodates the majority of Honeywell APU’s. With an expert team of highly-trained mechanics and engineers, the APU Service Centre is well equipped to support operators with multiple APU types.


Through our strong relationships with the various OEMs, we have developed successful alliances for the repair and overhaul of a wide range of APU parts. Our APU mechanics receive OEM training and all equipment and tooling is purchased directly from the manufacturer, which helps maintain the value of your APU at lease end.

We have a broad range of APU repair and overhaul capabilities including the following:


Honeywell 131-9A & 131-9B
Airbus A320 & Boeing B737NG


Honeywell 331-200 & 331-250
Boeing 767 /757 & Airbus A300


Honeywell 331-350
Airbus A330 & A340 Aircraft


Honeywell 85 Series
Boeing B737 Classics

We use lean production techniques and one-piece flow to increase performance. The APUs are built on an assembly line, with new, reworked, inspected and tested parts, delivered for reassembly on a just-in-time basis.


This results in reduced build and turn around times which save our customers money. The workshop repairs line replaceable units in-house, and provide APU end-of-lease work scope support. The APU turn around time can be tailored to suit any aircraft undergoing an end of lease check.
