Thurston Aircraft TSC-1A1 Teal for Sale — Buy or Sell Amphibious Light Aircraft Worldwide

The Thurston Aircraft Corporation TSC-1A1 Teal is a rare and historically significant amphibious light aircraft that occupies a unique niche in the world of general aviation. Designed by the highly respected aviation engineer David Thurston — one of America's most accomplished amphibious aircraft designers — the Teal was produced by Thurston Aircraft Corporation in the early 1970s as a practical, modern alternative to the aging fleet of Classic Era flying boats and amphibians. With its distinctive hull design, retractable undercarriage, and all-glass fiber composite construction, the TSC-1A1 Teal offered a contemporary approach to water-capable personal aviation that made it a notable achievement in general aviation engineering at the time of its introduction.

Whether you are searching to buy a Thurston Teal TSC-1A1 as a prized addition to your amphibious aircraft collection, seeking a capable water-based flyer for use from lake or coastal bases, or ready to sell your Teal and connect with knowledgeable buyers, Airplane Trade connects amphibious aircraft enthusiasts, private sellers, and specialty dealers worldwide.

About David Thurston and the Teal's Design Heritage

David B. Thurston was one of the foremost authorities on amphibious aircraft design in American aviation. His career spanned multiple iconic designs, including work on the Colonial Skimmer and the Lake Amphibian series — aircraft that brought practical water flying to private pilots for generations. When Thurston founded Thurston Aircraft Corporation, he applied his comprehensive expertise in hull design, hydrodynamics, and water-capable airframe engineering to create an aircraft that would take the amphibian concept forward into the modern era.

The TSC-1A1 Teal was the result of this vision: a two-seat amphibious monoplane built from fiberglass composite materials — an advanced construction approach for the early 1970s — that offered corrosion resistance superior to metal construction and a smooth, hydrodynamically efficient hull surface. The design reflected Thurston's deep understanding of the unique structural and aerodynamic compromises inherent in creating an aircraft that must perform safely on both water and land.

Design and Construction of the TSC-1A1 Teal

The Thurston TSC-1A1 Teal is a high-wing monoplane with a boat hull fuselage, retractable tricycle undercarriage, and pusher engine configuration — a layout that places the engine above and behind the cabin to keep the powerplant and propeller clear of water spray during water operations. The high-wing design maximizes buoyancy distribution and keeps the wings and fuel tanks away from the water surface, while the pusher configuration is a classic amphibious aircraft solution for propeller protection during water takeoffs and landings.

The airframe is constructed primarily from fiberglass reinforced plastic (FRP) composite, making the Teal one of the pioneering certified composite aircraft designs of the early 1970s. The composite hull offers inherent corrosion resistance — a critical attribute for aircraft regularly operated in salt or fresh water environments — and provides the smooth, fair surfaces that contribute to good hydrodynamic performance during water operations. The retractable undercarriage is electrically actuated and allows the aircraft to transition between water and land operations with the simplicity and reliability expected of a practical personal amphibian.

The cockpit accommodates two occupants side-by-side, with a large one-piece windshield providing good forward visibility and a practical panel layout for the navigation and communication equipment of the era. Many surviving Teal aircraft have been updated with modern avionics and engine management equipment over the decades, reflecting the care and enthusiasm of owners who appreciate the aircraft's unique capabilities and historical significance.

Powerplant and Performance

The TSC-1A1 Teal is powered by the Lycoming O-360-A1F6D, a horizontally opposed, four-cylinder, normally aspirated engine producing 180 horsepower. The Lycoming O-360 series is one of the most proven and well-supported engines in general aviation, with an extensive global network for parts, overhaul services, and operator experience. The pusher installation requires careful attention to engine cooling and exhaust routing, and the engine mounting design reflects Thurston's consideration of these challenges in the original engineering.

Performance highlights of the Thurston TSC-1A1 Teal include:

  • Cruise speed — approximately 105–115 knots (120–130 mph) at cruise power settings
  • Stall speed — approximately 52 knots, providing good slow-speed margins for water approach
  • Rate of climb — approximately 700 feet per minute at gross weight
  • Range — approximately 400–500 nautical miles depending on fuel load and power setting
  • Water takeoff distance — approximately 1,000–1,200 feet in favorable conditions
  • Maximum takeoff weight — approximately 1,980 lbs (898 kg)
  • Fuel capacity — approximately 40 US gallons

The Teal's performance is modest by current standards — as expected of a design from the early 1970s with a configuration optimized for water operations — but its practical amphibious capability more than compensates, opening up a world of water-based flying destinations inaccessible to conventional land planes.

The Amphibious Advantage

The defining characteristic of the Thurston TSC-1A1 Teal is its genuine amphibious capability — the ability to operate safely and practically from both paved runways and water surfaces. This operational flexibility opens up flying opportunities that no land-plane or seaplane can match on its own. Teal owners can fly into a conventional airport, then depart for a lake or coastal destination unreachable by road or land aircraft, combining the convenience of traditional general aviation with the freedom and adventure of water-based flying.

Operating a Teal requires specific training and currency in amphibious operations — including water taxiing, water takeoff and landing technique, and vigilant gear management to prevent inadvertent water landings with gear extended or land landings with gear retracted. The community of Teal owners and operators provides valuable support and shared experience for pilots learning to master these techniques.

Collector and Specialist Market

Today, surviving Thurston TSC-1A1 Teal aircraft are genuine collector items — rare examples of an innovative design from a pivotal era in general aviation history. The combination of limited production numbers, David Thurston's distinguished design heritage, composite construction pioneering, and practical amphibious capability makes the Teal a compelling acquisition for aviation collectors and water flying enthusiasts alike. Well-maintained examples with current airworthiness, documented maintenance histories, and engine overhaul compliance command strong interest in the specialist market.
