SC Aviation offers aircraft maintenance, repair and inspection services in Southern Wisconsin. Our team of trained maintenance professionals work 24/7 to provide aircraft owners with peace of mind along with expert guidance and representation in all phases of aircraft maintenance.

Maintenance is a Virtue.

The “Virtue of Maintenance” is a concept our staff has developed to work with your aircraft crew and flight department to ensure projects are properly managed… Our goal is to operate in the owner’s best interest. We are here to build a long-term relationship with you and your aircraft!


It goes back to our roots. Colony Brand’s flight department began operation over 70 years ago. During this time frame our parent company has ALWAYS expected a high level of reliability. Over the years, this tradition has shape and formed an organized process to ensure aircraft maintenance inspections and repairs are completed in a manner that is safe, timely and cost effective. As an outside maintenance customer, you can be assured that this level of service will be extended to you. SC Aviation treats your aircraft as if it is our own!

SC Aviation has over $5 million in parts inventory. Over the years we have found that keeping aircraft parts on hand has been extremely beneficial to our flight department and charter fleet. Our parts surplus give our fleet the advantage of shorter downtime, better cost control and greater flexibility. As an outside maintenance customer, we extend our inventory of Lear jet, Falcon and Hawker parts to you!
