What SteinAir does
SteinAir is a private, owner-operated avionics services and parts retailer headquartered at Faribault Municipal Airport (KFBL) in Minnesota, founded in 2000 and operating with a small team (1-10 employees). The company specializes in custom aircraft instrument panel fabrication and Mil-Spec wire harness assembly for the experimental and light sport aircraft market, particularly owners building Van's RV-series kit aircraft. Core technical capabilities include CNC-controlled wire cutting using Eubanks equipment, expert soldering with solder sleeves and splices, professional harness bundling, and laser engraving with acrylic paint fill; products are built using Mil-Spec components including M22759/16 Tefzel wire, machined crimp pins, and RG-400 coax. Production capacity includes roughly 200 engine monitor harnesses per month against an inventory base of nearly 1 million feet of aircraft-grade wire.
The business operates a hybrid go-to-market model. Individual avionics components (wire, connectors, circuit protection, switches, antennas, pitot/static equipment, probes, sensors, lighting, kits, tools, and books) are sold through a direct-to-consumer e-commerce storefront with publicly listed per-unit and per-foot pricing. Custom services, including full and partial panel builds, custom harness fabrication, custom cable manufacturing, pre-wiring services, panel finishing (automotive paint, hydro-graphics, carbon fiber overlay), and transponder checks, are delivered through a consultative, quote-based sales process that uses iterative PDF design revisions until customer approval, with final builds shipped in custom crates via UPS 3-Day. They support major avionics platforms including Garmin G3X Touch, Dynon SkyView/HDX, PS Engineering audio panels, and Avidyne IFD navigators. Pricing is publicly disclosed for components (e.g., $0.40/foot for 22AWG Mil-Spec wire, $150 for a 440-piece Terminal Kit, $960 Master Kit) but quote-based for custom work.

SteinAir competitors and assessment
Company assessmentBroad incumbents
- Dynon Avionics: Dynon is a leading avionics OEM for experimental and light sport aircraft (SkyView, D3, etc.) whose products SteinAir integrates into custom panels. Dynon competes with SteinAir indirectly via more pre-integrated solutions and pre-built harnesses sold direct to builders.
- Garmin: Garmin produces the G3X Touch avionics suite for experimental aircraft, a core product SteinAir integrates and supports. Garmin is both a key channel partner (referring customers to SteinAir as a G3Xpert) and a competitive threat if it expands pre-integrated offerings for homebuilders.
- Aircraft Spruce & Specialty: Aircraft Spruce is the largest mail-order retailer of aviation parts, materials, and avionics components, serving homebuilders and restorers across North America. It competes with SteinAir on the e-commerce component retail side across overlapping SKUs like wire, connectors, switches, and tools.
Others
- Avidyne: Avidyne manufactures IFD-series FMS/GPS navigators widely used in experimental and retrofit installations that SteinAir integrates. It is primarily an avionics OEM partner but also publishes upgrade guides that enable more DIY installations by builders.
- Van's Aircraft: Van's Aircraft is the dominant kit manufacturer of RV-series experimental aircraft (RV-8/9/10/12/14), which represent SteinAir's largest customer segment. It is not a direct competitor but a critical channel partner whose build volumes drive SteinAir's panel/harness demand.
- Sporty's Pilot Shop: Sporty's is a major pilot supply retailer offering avionics tools, training, and accessories including products that overlap with SteinAir's small tools, books, and accessory catalog. It does not perform custom panel/harness services but competes on retail pilot supplies.
- Chief Aircraft: Chief Aircraft supplies avionics, parts, and accessories for general aviation and experimental builders. It overlaps with SteinAir's retail component business and has offered panel-building services historically, making it a partial competitor on both the retail and service sides.
Direct peers
- Pacific Coast Avionics: Pacific Coast Avionics is a well-known avionics shop that performs custom avionics installations and panel work for experimental and general aviation aircraft. It competes most directly with SteinAir on bespoke panel/harness services in the experimental market.
Emerging players
- GRT Avionics: GRT Avionics designs and manufactures electronic flight instruments, autopilots, and engine monitors specifically for experimental amateur-built aircraft. It is a complementary OEM whose products SteinAir integrates and a partial competitor for the same builder customer.
- Advanced Flight Systems: Advanced Flight Systems manufactures avionics and pre-engineered panel/wiring solutions targeted at experimental aircraft builders. It overlaps with SteinAir by offering integrated harness and panel products in the same Van's RV and experimental LSA ecosystem.
