Aero-Works Aerolite 103. The Aero-Works Aerolite 103 is an American single seat, high-wing, pusher configuration ultralight aircraft, designed by Terry Raber and introduced by Aero-Works, Inc, of Millersburg, Ohio, in 1997. The aircraft's model number indicates that it was designed to comply with the Federal Aviation Administration FAR 103 ultralight rules.

Production of the aircraft ended in 2005 when the manufacturer went out of business. The rights to the design were purchased by its original designer, the aircraft updated with an updated aluminum fuel tank and put  back into production in 2013 by U-Fly-It Light Sport Aircraft, LLC of DeLand, Florida.

Development
The aircraft was designed to meet the requirements of FAR 103 Ultralight Vehicles, including maximum  empty weight.
 
The builder-achieved empty weights vary from  to , with  being typical. To remain under the FAR 103 empty weight requires the use of a light-weight engine, such as the  2si 460-F35 or the  Hirth F-33.

Design

The Aerolite 103 features a high wing with half-span flaps that are extended by use of an overhead bellcrank to a maximum of 40 degrees. The flight controls are three-axis and are actuated by a wheel mounted on a control column via flexible push-pull cables and conventional rudder pedals connected to the rudder by cables. The engine throttle is a twist-grip type and incorporates a brake lever to operate the non-differential mechanical drum brakes installed on the main wheels of the tricycle landing gear.

The aircraft has conventional nose wheel steering connected to the rudder pedals. The main landing gear utilizes sprung-tubes for suspension and absorbing landing loads. There is a fourth small caster-wheel under the tail, because when the pilot's seat is unoccupied the aircraft rests on its tail, due to the aircraft's empty center of gravity.

The Aerolite 103 is sold as an assembly kit aircraft. The kit includes an illustrated assembly manual and pre-built fuselage, wings, control surfaces, jury struts and struts. The wings are covered by the builder with pre-sewn Dacron envelopes. The company estimates the time to complete the airframe at 60–80 hours. The kit does not include powerplant, propeller or instruments.

When the aircraft was first introduced the standard engine was the  2si 460-F35, with the  Rotax 447 optional. In 2009 the standard recommended engine was the Rotax 447, with the  Rotax 503 single carburettor engine optional. In 2021 an electric aircraft option was added as the manufacturer offered a complete electric drivetrain and up to four batteries as an alternative to gasoline powerplants.

Aerobatics and spins are prohibited.
