Where I lived "ALL OVER"  mostly in the "busch"  "behind the black stump" without electricity for over ten years! Great years of my life!!    (click here for more details)

Represented the Australian Soaring Team as a repair technician in Poland during the 1968 World Championship.

As a result I was invited to obtain specialized training in the repair and modifica­tion of composite aircraft structures by FLUG und FAHRZEUGWERKE in Switzerland. This company engaged me to perform major modifications to some 16 DIAMANT sailplanes. Most of these were located in Australia and the U.S.A. The modifications were completed by 1969.. I also spent an additional year or so in Germany with two other sailplane manufacturers to become trained as their representative in the USA for repairs and maintenance of their aircraft.


1988- Present

Design and construction of a 97 ft ocean going catamaran. I am also accepting assignments as a consultant for composite structures and tooling.

Some repair and fabrication work of composite aircraft components is still accepted and is a part of the income needed to move forward on the CAT.


Manager and chief engineer of Fred Jiran Glider Repairs. (A sole proprietorship).
CEO of Composite Development Corp. (formed 1977).
As the chief engineer of both organizations I became responsible for the successful completion of some one hundred NASA contracts and hundreds of industrial and experimental aircraft projects.
I sold my interest in Composite Development Corporation to Chadd Aero Restoration in 1988 and assumed the D.B.A. CODEVCO
