A Northern Plains repair station for aircraft owners who need the whole job handled.
Roger Wilco Aviation Services operates from Hangar 3 at 3701 N. Aviation Avenue in Sioux Falls, South Dakota. The shop is built for aircraft owners who need avionics, airframe, powerplant, NDT, fabrication, and documentation coordinated by one accountable team instead of scattered across disconnected vendors.
RWAS supports owners across South Dakota, Nebraska, Iowa, Minnesota, North Dakota, Wyoming, and Montana with FAA Part 145 repair-station discipline, Garmin dealer access, in-house panel fabrication, and practical aircraft-maintenance judgment.

Garmin panel work, fabrication, and return-to-service documentation coordinated from the RWAS Sioux Falls shop.
Commercial-intent services with a real address behind them.

For service planning, include the aircraft make and model, N-number, current location, known squawks, photos, logbook context, desired downtime window, and the decision you are trying to make. RWAS can then route the request to avionics, maintenance, NDT, fabrication, or pre-buy support without starting from a generic intake.
