What NexAir Avionics does

NexAir Avionics is a privately held, FAA-certified avionics integration and aircraft restoration shop founded in 2007 by Dave Fetherston and based at Plymouth Municipal Airport (KPYM) in Plymouth, Massachusetts. The company operates from two 14,400 sq ft hangars with 15,000 sq ft of total shop space and holds FAA Repair Station certification (#N4OR087B). Its core offering is the NexAir AIR Program (Aircraft Integration and Reengineering Program), under which NexAir designs, sources, and installs fully customized avionics suites — primarily Garmin and Avidyne hardware including GTN 750/650 Xi navigators, TXi and Vantage 12 flight displays, DFC90 and GFC500 autopilots, GTX/AXP ADS-B transponders, and SiriusXM/PlaneSync connectivity — built around individual pilot flying style, mission, and budget.

Revenue is generated through project-based avionics installations and upgrades (typical flyaway-special packages $26,250-$47,600 for Cirrus panels), trade-in promotions for legacy GNS 430/530 units, biennial VFR/IFR certifications (14 CFR 91.411/91.413), RVSM certification for FL 290-410 operations, troubleshooting and repair services, mobile on-site service via a dedicated van, and full Spinner-to-Tail aircraft restoration services. Distribution is direct: customers contact the sales team, fly into or ship aircraft to Plymouth, or engage the mobile van regionally; the company also accepts remote quote requests nationally.

NexAir serves a fragmented general aviation customer base — with primary emphasis on Cirrus SR20/SR22 owners, plus Beechcraft, Cessna, turboprop (Piper Meridian, Cessna Caravan, King Air), helicopter, experimental, and paramilitary/government operators. Authorized dealer relationships span Garmin, Avidyne, PS Engineering, Aspen Avionics, L-3 Communications, S-Tec, Pratt & Whitney Canada, Bose, David Clark, AmSafe, Shadin, CiES, JPI, LoPresti, and Sandel. The company is bootstrapped, family/founder-controlled, and operates with a disclosed headcount of 1-10 employees.

Expansion highlights6 records

Broad incumbents

• Avidyne Corporation: Avionics OEM whose products (IFD series, Vantage 12, DFC90) form the other pillar of NexAir's offerings. Comparable as a key supplier and another potential channel-bypass risk for the installation business.
• Garmin: Primary OEM supplier whose products NexAir installs (GTN Xi, TXi, GFC500). Comparable as the upstream technology partner and potential long-term competitive threat if Garmin expands direct installation or service programs.
• Elliott Aviation: Multi-location aviation services company offering avionics installations, paint, interior, and airframe MRO. Comparable to NexAir on avionics work, but operates at significantly larger scale across piston, turboprop, and jet segments.
• Duncan Aviation: One of the largest business aviation MRO networks in North America with extensive avionics installation, modification, and repair capabilities. Overlaps NexAir in avionics retrofits but serves a much larger and more corporate-jet-centric customer base.

Direct peers

• Sarasota Avionics: Avionics installation and repair facility in Florida offering Garmin and other OEM integrations, panel upgrades, and Autopilot/Synthetic Vision services. Directly comparable in scope of services and target customer base.
• SteinAir: Specialty avionics installation shop with strong Cirrus and experimental aircraft focus, offering custom panel builds and ADS-B upgrades. Closely comparable to NexAir in customer segment, product mix (Garmin/Avidyne), and integration-first positioning.
• Pacific Coast Avionics: Full-service avionics sales, installation, and repair shop authorized for major GA brands, serving Cirrus, Cessna, and Beechcraft owners. Comparable as a multi-OEM authorized avionics integrator targeting the same GA owner-operator segment.
• Mid-Continent Instruments and Avionics: Manufactures and repairs general aviation instruments and avionics at its own FAA Repair Station in Wichita, KS. Directly comparable to NexAir as a combined avionics manufacturer/MRO/installation shop with deep GA focus.
• Avionics Place (formerly Avionics Installations): Independent avionics installation and repair shop specializing in general aviation retrofits. Comparable to NexAir as a small, brand-authorized integrator focused on panel upgrades for personal aircraft owners.

Regional players

• Banyan Air Service: FBO and aviation services company in Fort Lauderdale, FL offering avionics sales, installation, and repair. Comparable business model to NexAir (FBO-anchored avionics shop) but focused on the Southeast U.S. market.
