The Mathews Petit Breezy is an American
ultralight aircraft
Ultralight aviation (called microlight aviation in some countries) is the flying of lightweight, 1- or 2-seat fixed-wing aircraft. Some countries differentiate between weight-shift control and Aircraft flight control system, conventional three-a ...
that was designed by Lyle Matthews in conjunction with his partners Al Petit and Kindall and Wink Turner. It was made available in the form of plans for
amateur construction. The aircraft was inspired by the larger
RLU-1 Breezy.

Design and development
The Petit Breezy was designed to comply with the US
FAR 103 Ultralight Vehicles
Ultralight aircraft exist outside of the United States. In most countries, ultralights are a class of aircraft. A completely different legal concept is valid within the USA. The FAA makes explicitly clear that ultralight vehicles are not air ...

strut-braced
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in ...
high-wing
A monoplane is a fixed-wing aircraft configuration with a single mainplane, in contrast to a biplane or other types of multiplanes, which have multiple wings.
A monoplane has inherently the highest efficiency and lowest drag of any wing config ...

pusher configuration
In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with propulsion device(s) after the engine(s). This is in contrast to the more conventional tractor configuration, wh ...

The aircraft is made from riveted
aluminum
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has ...

doped aircraft fabric
Aircraft fabric covering is a term used for both the material used and the process of covering aircraft open structures. It is also used for reinforcing closed plywood structures. The de Havilland Mosquito is an example of this technique, as are ...

jury struts
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of struts, which act in ...

aileron
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in roll (or movement aroun ...
s. The tail is a strut-braced
cruciform tail
The cruciform tail is an aircraft empennage configuration which, when viewed from the aircraft's front or rear, looks much like a cross. The usual arrangement is to have the tailplane, horizontal stabilizer intersect the vertical tail somewhere ...

The fuselage (; from the French language, French ''fuselé'' "spindle-shaped") is an aircraft's main body section. It holds Aircrew, crew, passengers, or cargo. In single-engine aircraft, it will usually contain an Aircraft engine, engine as wel ...
consists of an aluminum keel tube that runs from the nose wheel to the tail. The pilot is accommodated on an open seat mounted to the main keel tube and a second seat can be fitted under the wing.
In 2011 plans were still available for the design from the
Vintage Ultralight Association. Construction time from the plans is estimated at 200–300 hours
