The TeST TST-14 Bonus is a Czech high-wing, T-tailed, two-seats-in-tandem glider and motor glider that was designed and is produced by TeST Gliders.[1][2][3]

Design and development

The TST-14 motor glider was designed for private owner and flying school use and as such features wing tip wheels that allow independent taxiing and take-off.[1][3]

The TST-14 is constructed from composite materials, with the forward-swept wing a ribless composite sandwich structure. Each wing weighs 40 kg (88 lb) and has a single spar made with a carbon fibre composite flange plate and a polyurethane foam/fibreglass composite web plate. Glidepath control is by upper surface air brakes made from aluminium. The motor glider version is powered by a retractable 50 hp (37 kW) Rotax 503UL two-stroke powerlant. Extension and retraction of the engine is fully automatic, controlled with two cockpit-mounted buttons and actuated by two electric servo motors. The landing gear consists of dual fuselage-mounted tandem mainwheels and wing tip-mounted wheels.[1][4][5]

The aircraft was type certified to the Joint Aviation Authorities JAR 22 standard for gliders on 10 Dec 2001. The TST-14 was not certified in the United States as the company explains, "due to the expense involved". The aircraft can be registered with the US Federal Aviation Administration as a Special Light Sport Aircraft glider or in the Experimental - racing/exhibition category.[2][5][6]
