Rocky Mountain Aircraft

What Rocky Mountain Aircraft does

Rocky Mountain Aircraft is a privately held Canadian aviation services company founded in 1982 by George and Liane Stevenson, headquartered at Springbank Airport in Calgary, Alberta. The firm specializes in the De Havilland Canada DHC-6 Twin Otter aircraft and Pratt & Whitney Canada PT6A turboprop engines, offering maintenance, repair, and overhaul services both at its 25,000+ square foot Springbank facility and via mobile field teams deployed worldwide. It is positioned as a Transport Canada-, EASA-, and FAA-approved maintenance organization with in-house engineering and certification capabilities, and is self-described as a global authority on the Twin Otter platform.

The company's product portfolio spans five core service lines — Maintenance, Engineering & Certification, Custom Modifications, Avionics, and Parts & Accessories — supplemented by Aircraft & Engine Sales & Leasing and AOG (Aircraft on Ground) Support. Its proprietary intellectual property includes an extensive portfolio of TCCA and FAA Supplemental Type Certificates (STCs) and Production Design Approvals (PDAs), covering items such as Digital De-Ice Timers, Bonded Roof Panels, Fuel Manifold Tubes, an aluminum Cabin Roof Escape Hatch, Floor Panels, Elevator Trailing Edge Replacements, a Garmin G700TXi avionics upgrade (STC SA25-42 for 1900D), and the FAA STC SA09761DS for the Genesys S-TEC 3100 digital autopilot on Twin Otter. The firm is an approved dealer and certification partner for Garmin, Genesys Aerosystems, Avidyne, Universal Avionics, and Acron Aviation/Lynx.

Rocky Mountain Aircraft generates revenue through a mix of professional services (maintenance, engineering, custom modifications), hardware sales and rentals (parts, rotables, proprietary manufactured parts), one-time aircraft and engine sales/leasing of Twin Otters and PT6A engines, and licensing/royalty-style revenue from STC-certified proprietary parts. GTM is sales-led and relationship-driven, combining direct enterprise engagement with facility-based work, field service deployment globally, and presence at industry trade shows (NBAA, Oshkosh, Heli-Expo). Customer segments span special mission operators, regional airlines, government agencies, general aviation operators, and private aircraft owners, with no public revenue disclosure and a 51–100 employee headcount.
