Phoenix Aircraft Ltd was formed in 1958 to develop and produce ultra-light and light aircraft and engines, with particular emphasis on the manufacture of kits of parts for amateur re-assembly.

 

The company has begun by redesigning the pre-war Luton Minor single seat light aeroplane, and is also building a new version of the two-seat Luton Major.  Both of these types were developed in their original form by Luton Aircraft Ltd, which ceased to exist during the war when its premises were destroyed. Design rights of Luton aircraft have been acquired by Phoenix Aircraft Ltd.

The Phoenix LA4a Minor

The first LA4 Minor flew in 1937 and proved suitable for construction by amateurs and for operation by pilots of limited experience. Examples were built pre-war in England and other parts of the world.

 

Many improvements are incorporated in the new LA4a Minor and the construction has been simplified. In particular, a fixed vertical tail fin is now fitted together with a more robust landing gear similar to that of the Piper Cub.

 

Phoenix Aircraft supplies parts and components of the LA4a Minor to order and will offer complete kits of parts in due course. Plans are available through the Popular Flying Association.
