The Schweizer SGS 2-32 is an American two-seat, mid-wing, two or three-place glider built by Schweizer Aircraft of Elmira, New York.[3]

The 2-32 was designed to be the highest performance two-place glider available, when it first flew in 1962. The 2-32 has been used as a tourist glider, trainer, cross-country and high-altitude sailplane and has set many US and world records. A total of 87 aircraft were completed.[1][3][4][5]

Design and development

The SGS 2-32 was conceived as a mass-produced sailplane of modest performance to act as a step-up from the SGU 2-22 trainer then in common use in North America. After careful examination of the potential market, the company decided to produce a higher performance sailplane with a greater wingspan instead.[4]

The 2-32 design was started in 1961 and completed with certification under type certificate G1EA on 19 June 1964.[4][6]

The 2-32 is all-metal, with a semi-monocoque aluminum fuselage and cantilever wings of 57 foot (17.37 m) span. It has top-and-bottom divebrakes and an all-flying stabilator tail.[1][3]

The aircraft seats two or three, with one seat in the front cockpit and a double bench seat in the back suitable for two smaller people of 150 lb (68 kg) each, maximum. The aircraft is often described as a "21⁄2 seater".[1][3][4]

The ability to carry two passengers, plus its complete and comfortable interior has made the 2-32 a popular aircraft with commercial glider operators for conducting tourist flights. The ability to carry two passengers doubled profitability for rides.[4]

The first customer aircraft were delivered in 1964, shortly after certification was completed.[4]

The type certificate is currently held by K & L Soaring of Cayuta, New York. K & L Soaring now provides all parts and support for the Schweizer line of sailplanes.[6][7]

Derivative designs

The SGS 2-32 has been the basis of several derivative designs, including:[5]

Operational history

As soon as it entered service many pilots realized that this high performance two-place sailplane would be ideal to break many of the two-place records previously set by lower performance gliders.[3][4]

At one time the 2-32 held the two-place speed records over 100 km, 300 km and 500 km courses, as well as many distance, out and return and altitude records in both the men's and women's categories. 2-32s were also flown in the 1964 US Nationals.[3][4]

Some of the records set by pilots flying SGS 2-32s include:

  • World record two-place out and return flight, 404 miles (654 km), May 23, 1970, Joe Lincoln and Cris Crowl. Lincoln's 2-32, named Cibola, had special longer wings of 67-foot (20 m) span installed that increased performance further.[4]
  • World record two-place speed over 100 km (63 miles) Triangle, 74 mph (120 km/h), 1971, Joe Lincoln.[4]
  • World record two-place feminine absolute altitude 35,463 feet (10,809 m) and altitude gain 24,545 feet (7848 m), 5 March 1975, Babs Nutt.[1][3]

In May 2014 there were still 58 2-32s registered in the USA[11] and one in Canada.[12]

In USAF service at the United States Air Force Academy the 2-32 was known as the TG-5.

Aircraft on display

The National Soaring Museum has two SGS 2-32s in its collection, N2767Z and N8600R, the prototype.[13][14] N8600R is currently on loan to and on display at the Evergreen Aviation & Space Museum in McMinnville, Oregon.[15]
