Hants and Sussex Aviation / HSA
Hants and Sussex Aviation (HSA) was formed in 1946 at Portsmouth Airport, Portsmouth, Hampshire, England, by the Hawes family (A.H.Hawes, W.E.Hawes, A.E.Hawes & F.G.Lewis) and initially worked on component manufacture and repair for military aircraft.
The first Hants and Sussex office was located above the archway of what was then the Bailey family business of builders and estate agents in Bognor Regis. The company’s first workshop was in Fratton, Portsmouth and comprised of an estimated 1,500 square feet. They relocated to the edge of what was then Portsmouth Municipal Airport in 1947 and have been here ever since.
In 1953, HSA designed its first aircraft. This was the H&S Herald. The Herald was a single-seat ultra-light aircraft with a fixed tricycle undercarriage and powered by a 40 h.p. Aeronca-JAP J-99 piston engine. The Herald made flight tests at Portsmouth Airport in 1953, but these revealed that it had a poor performance and the aircraft was grounded and dismantled in 1955.
HSA were contracted in 1965 to build one of the pre-World One flying replica aircraft for the film Those Magnificent Men in their Flying Machines. HSAs aircraft was the Antoinette IV which they powered by a de Havilland Gypsy I engine.
HSA then concentrated on work on the overhaul, modification and repair of aircraft engines and components. In late 1976 the firm advertised its work on the overhaul and repair of Continental piston engines for aircraft. By September 1986 HSA were overhauling and modifying Rolls-Royce Dart and Pratt and Whitney PT-6 turboprop engines. HSA still carry on trading within the aviation support industry in 2008.
