Role Side-by-side two seat homebuilt light-sport aircraft
National origin Switzerland
Manufacturer MSW Aviation, built by Wassmer Aviation
First flight 26 June 2009
Developed from MSW Votec 322

The MSW Votec 252T is a single engine kitbuilt light-sport aircraft with side-by-side seating for two, designed and built in Switzerland and was first flown in 2009. By October 2011 only this first prototype has flown.

Homebuilt aircraft planes constructed by persons for whom this is not a professional activity

Homebuilt aircraft, also known as amateur-built aircraft or kit planes, are constructed by persons for whom this is not a professional activity. These aircraft may be constructed from "scratch," from plans, or from assembly kits.

Light-sport aircraft aircraft weight classification generally less than 600 kg (1300 lb) and of otherwise simple construction and operation

A light-sport aircraft (LSA), or light sport aircraft, is a fairly new category of small, lightweight aircraft that are simple to fly. LSAs tend to be heavier and more sophisticated than ultralight aircraft, but LSA restrictions on weight and performance separates the category from established GA aircraft. There is no standard worldwide description of an LSA.

Switzerland federal republic in Central Europe

Switzerland, officially the Swiss Confederation, is a country situated in western, central, and southern Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The sovereign state is a federal republic bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a landlocked country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning a total area of 41,285 km2 (15,940 sq mi). While the Alps occupy the greater part of the territory, the Swiss population of approximately 8.5 million people is concentrated mostly on the plateau, where the largest cities are to be found: among them are the two global cities and economic centres Zürich and Geneva.

Design and development

The Votec 252T is a side-by side seat development of MSW's earlier tandem seat Votec 322. The prototype, powered by a modified Lycoming IO-540-J3A5 flat-six engine, marries the wooden wings and empennage of the latter to a new, carbon fibre fuselage, though a carbon fibre wing is under development. All flying surfaces are straight tapered and square tipped, the wing low mounted and the tailplane located on the upper fuselage; the rudder extends down to the keel. The ailerons are balanced with external spades. [1]

Tandem arrangement in which people, machines, or animals are in line behind one another facing forward

Tandem, or in tandem, is an arrangement in which a team of machines, animals or people are lined up one behind another, all facing in the same direction.

Lycoming O-540 family of flat-six piston aircraft engines

The Lycoming O-540 is a family of air-cooled six-cylinder, horizontally opposed fixed-wing aircraft and helicopter engines of 541.5 cubic inch displacement, made by Lycoming Engines. The engine is a six-cylinder version of the four-cylinder Lycoming O-360.

Flat-six engine horizontally opposed 6-cylinder piston engine

A flat-six or horizontally opposed-six is a flat engine with six cylinders arranged horizontally in two banks of three cylinders on each side of a central crankcase. This should not be confused with the Opposed-piston engine. The pistons are mounted to the crankshaft such that opposing pistons move back and forth in opposite directions at the same time, somewhat like a boxing competitor punching their gloves together before a fight, which has led to it being referred to as a boxer engine.

The Votec 252T has a cabin over the wing, with baggage space behind the seat, under a single piece canopy. It has a fixed tricycle undercarriage with fuselage mounted cantilever legs and with speed fairings on all wheels. The nosewheel casters; there is a small tailskid for rudder protection. [1]

Cantilever beam anchored at only one end

A cantilever is a rigid structural element, such as a beam or a plate, anchored at one end to a support from which it protrudes; this connection could also be perpendicular to a flat, vertical surface such as a wall. Cantilevers can also be constructed with trusses or slabs. When subjected to a structural load, the cantilever carries the load to the support where it is forced against by a moment and shear stress.

Aircraft fairing

An aircraft fairing is a structure whose primary function is to produce a smooth outline and reduce drag.

The first prototype flew on 26 June 2009. A second prototype with a 260 kW (350 hp) Lycoming AEIO-580 engine, redesignated the Votec 352T, is under development but had not flown by October 2011. [1]

All Stinson model 108, 108-1, 108-2, 108-3 and 108-4 aircraft were built by Stinson at Wayne, Michigan. When Stinson sold the type certificate to Piper in 1949, approximately 325 airplanes of the 5,260 model 108s built by Stinson were complete but unsold. These 325 model 108s went to Piper as part of the sale. Piper then sold that inventory as the Piper-Stinson over the next few years.
