Helicopter Specialties Airbus H125 completion at Southern Wisconsin Regional Airport (KJVL) in Janesville, Wisconsin.


Halfway between Rockford, Illinois, and Madison, Wisconsin, is a surprisingly full-featured helicopter maintenance, repair, and overhaul (MRO) shop and completions and customization center: Helicopter Specialties in Janesville, Wisconsin.

Part 145 repair station? Yep. OEM service centers? Check. Certified on 24 aircraft models, from the Airbus EC155 to the Robinson R22, with Bell and Enstrom and Leonardo and MD Helicopters in between? That’s them.

Painting, avionics, engineering, medical interiors, specialized machining, consulting, and transportation are more of what, but not everything, they do.
