TEXAS SKYWAYS, INC.

What TEXAS SKYWAYS, INC. does

Texas Skyways, Inc. is a privately-held aircraft modification company founded in 1985 and headquartered at Boerne Stage Airfield (5C1) in Boerne, Texas, just northwest of San Antonio. The company specializes in Supplemental Type Certificates (STCs) for Cessna aircraft, holding 47 FAA-approved STCs — described as the largest collection of any aircraft mechanic worldwide — and claims over 2,500 Cessna modifications completed globally since incorporation. Its core technology centers on certified engine modifications (O-470-U/TS, IO-520-F/TS, IO-550-F/TS producing 250–300 HP with 2,500-hour TBO), propeller upgrades (Hartzell aluminum, MT composite, McCauley), and airframe upgrades (STOL kits, vortex generators, digital fuel senders, electronic ignitions, power-flow exhausts), supplemented by spare parts, modified carburetors, and a proprietary six-point engine mount system.

The company operates a sales-led, direct-to-customer model targeting Cessna 100 and 200 series aircraft owners (172, 180, 182, 185, 205, 206, 210 models). Revenue is generated through one-time hardware sales, STC licensing and engineering services, and professional installation performed by in-house IA and A&P mechanics. Pricing is quote-based and not publicly disclosed; customers contact the company via phone or email. The company also distributes STCs and installation instructions to third-party mechanics globally, extending reach beyond in-house installation capacity, and offers international shipping with customs management.

The team is small — 8 employees including 3 IA Mechanics, 4 A&P Mechanics, 2 Test Pilots, plus administrative and apprentice staff — and has been built around deep veteran aviation expertise. The late founder Jack Johnson piloted for 70 years and earned the FAA Wright Brothers Master Pilot award. The business is founder-family controlled, with no disclosed institutional investors, no public listing, and minimal public digital footprint (no listed social media profiles, no public pricing).

Scale indicators3 records

Recent moves6 records

Expansion highlights4 records

Broad incumbents

• Lycoming Engines: Dominant OEM of piston aircraft engines used across the Cessna single-engine fleet. Relevant incumbent whose certified engines and parts influence the aftermarket upgrade opportunity Texas Skyways addresses.
• Hartzell Propeller: Major general aviation propeller OEM selling aluminum and composite propellers, including the Voyager line that Texas Skyways offers. A broader incumbent supplier on which Texas Skyways depends rather than a direct competitor.
• Continental Motors: OEM of the IO-520 and IO-550 engine families that Texas Skyways modifies and STC-installs. Acts as an upstream incumbent supplier and a baseline reference for the upgrade market.

Direct peers

• Air Plains Services: Specializes in engine and avionics upgrades for Cessna 172 and 180 aircraft via STCs, including 180 HP and other high-performance kits. The closest direct competitor to Texas Skyways in the Cessna 100/200 series upgrade market.
• Tornado Alley Turbo: Specializes in turbocharger STC installations for Cessna 182 and 206 aircraft. Competes in the same Cessna 100/200 series performance upgrade ecosystem as Texas Skyways.
• Western Skyways, Inc. Montrose, CO-based aviation MRO and engine modification company that Texas Skyways has directly collaborated with on STC development for the Cessna 421. Operates a similar aircraft-modification and STC-driven business model anchored to engine and airframe upgrades.
• RAM Aircraft, LP: Provides engine overhauls, STC engine upgrades, and parts for Cessna and other general aviation aircraft. Overlaps Texas Skyways on engine modification services and STC-driven aftermarket sales.
• Blackhawk Aerospace Technologies: Develops and sells XP Engine Upgrade STCs for Cessna 182 and 210 series, plus other GA platforms. Competes head-to-head with Texas Skyways' O-470/IO-520/IO-550 engine STC offerings.

Emerging players

• Power Flow Systems: Manufacturer of tuned exhaust STC systems for Cessna 180/182/210. Listed as a Texas Skyways airframe upgrade partner, but also sells competing exhaust-based performance upgrades in the same airframes.
• Selkirk Aviation: Maker of extended baggage compartment STC kits for Cessna 180/185/206, distributed via Texas Skyways. A niche accessory peer sharing the same Cessna owner channel and STC-based go-to-market.
