Basler Turbo Conversions LLC

What Basler Turbo Conversions LLC does

Basler Turbo Conversions LLC is a privately held aerospace manufacturer founded in 1988 and headquartered at Wittman Regional Airport in Oshkosh, Wisconsin, where it operates a 75,000 square foot production facility employing 51-100 staff. The company's sole substantive product is the BT-67, a remanufactured turboprop conversion of the Douglas DC-3/C-47 airframe powered by Pratt & Whitney PT6A-67R engines with Hartzell 5-blade propellers and certified to FAR Part 25 standards under FAA Supplemental Type Certificate SA4840NM, an authorization held exclusively by Basler.

The technical platform converts existing DC-3/C-47 airframes into modernized BT-67 aircraft with up to 30,000 lbs maximum take-off weight (up from 26,900 lbs), 14,000 lbs maximum useful load, 1,860 nautical mile range, and 13-hour endurance. Customers select between two integrated avionics suites (Genesys and Sandel) and additional mission-configuration options, including cockpit armor, countermeasures, weapon hardpoints, ISR/FLIR stations with OBOGS, belly/ceiling openings, retractable skis, and zone-specific climate control. The conversion cycle runs 9-12 months per unit depending on configuration complexity. Basler also holds Part Manufacturing Authority for 6,500 parts and maintains an inventory of over $24 million across 80,000+ line items supporting the global BT-67 fleet on a 24/7 basis.

The business model operates through three revenue streams: one-time aircraft sales and conversions (custom quotes, no public pricing), recurring aftermarket parts distribution, and an annual technical documentation subscription via AirCorps Library (covering ~23,000 engineering drawings and 220+ service bulletins). Go-to-market is direct enterprise sales through a field-representative network covering Thailand, Africa, the Philippines, Canada, Argentina, Chile, Peru, Ecuador, and Colombia, alongside US headquarters-led engagement. The customer base spans military and government operators (Colombia, Mali, Mauritania, El Salvador, Guatemala, Royal Thai Air Forces, Colombian National Police, NAWCAD), commercial aviation service providers (Kenn Borek Air, Bell Geospace, Airborne Support, Enterprise Aviation, Cargo North, Spectrem Air), and scientific and polar research organizations (Alfred Wegener Institute, Polar Research Institute of China).

Direct peers

• Marshall Aerospace and Defence Group: Marshall Aerospace performs deep maintenance, modification, and special-mission conversions (ISR, air-to-air refueling, etc.) on military and civilian aircraft, holding numerous STCs. Comparable as a UK-based special-mission modifier serving defense and government customers globally.
• Field Aerospace: Field Aerospace performs FAA STC-based aircraft modifications, special-mission conversions (ISR, electronic warfare, maritime patrol), and avionics upgrades on multiple platforms. Direct comparable as a third-party special-mission modifier serving military and government customers.
• Sierra Industries: Sierra Industries holds multiple FAA STCs for King Air engine conversions (turboprop and turbofan) and interior refurbishments, remanufacturing older Beechcraft airframes with modern systems. Directly comparable STC-based remanufacturing business model targeting utility/government customers.
• Viking Air: Viking acquired type certificates for legacy de Havilland Canada aircraft (DHC-6 Twin Otter, DHC-2 Beaver, CL-215/415) and produces remanufactured/new-production versions. Highly comparable to Basler's philosophy of modernizing proven legacy airframes, though with broader product portfolio and type ownership.
• Nextant Aerospace: Nextant remanufactures legacy business jets and King Airs (400XT, 400XTi, 604XT) into modernized aircraft with new engines and avionics under FAA STCs. Closest direct comparable to Basler's remanufacturing/upgrade business model, though focused on business aviation rather than tactical transport.
• Aviation Partners: Aviation Partners designs and certifies blended winglet modifications (including the popular Boeing 737 Split Scimitar Winglets) under FAA STCs, retrofitting in-service aircraft for efficiency gains. Comparable as a STC-driven aftermarket modification specialist serving commercial and business aviation.

Broad incumbents

• Textron Aviation (King Air): Textron Aviation produces the King Air 360/260 and Cessna Caravan, factory-new turboprop platforms competing directly with the BT-67 in utility, ISR, and cargo missions. Competes for the same government and commercial customers but as an OEM with new-production rather than remanufactured aircraft.
• Lockheed Martin (C-130): Lockheed Martin's C-130J Super Hercules is the dominant tactical transport competing with the BT-67 for military airlift, special-mission, and ISR contracts globally. Competes in the same mission space but as a vastly larger OEM with new-production platforms at substantially higher cost.
• Airbus Defence and Space (C295): Airbus C295 is a new-production tactical/maritime turboprop transport serving many of the same emerging-market air forces that operate the BT-67 (Colombia, Thailand, Mali-adjacent). Competes head-to-head for tactical transport procurement but as a major OEM platform.

Regional players

• Saab (340/2000 regional turboprops): Saab's 340 and 2000 regional turboprops serve utility, maritime patrol, and ISR roles after special-mission conversions. Comparable in turboprop configuration and mission application, though primarily serving different geographic markets (Europe, Asia-Pacific) than Basler's emerging-market focus.
