PILOT error contributed to the fatal crash of a homemade replica Spitfire at an Adelaide air show in March, an investigation has found.
Roger Stokes, 73, died when the plane he built from a kit nosedived into a factory car park in Adelaide's northern suburbs as he took part in a local air show on March 17.
The Australian Transport Safety Bureau (ATSB) on Tuesday released a report into its investigation, which found the plane stalled before descending steeply into the ground.
It found Mr Stokes inadvertently allowed the airspeed to drop while co-ordinating a landing clearance with air traffic control and flying a low-level circuit in turbulent conditions.
"In the subsequent turn (downwind) to adjust the circuit the aircraft aerodynamically stalled, descended steeply, and impacted the ground," the report said.
"The aircraft was prone to aerodynamically stall with little or no aerodynamic precursors and it was not fitted with a stall warning device, increasing the risk of inadvertent stall."
The ATSB said pilots should be aware of the extra demands involved in air display flying, which are different from normal flying.
"Pilots who participate in air displays should consider the demands involved, and to the extent possible, ensure that the complete sequence, including landing, is planned and rehearsed," it said.
Owner-pilots should also consider the benefits of fitting a stall-warning device, even though amateur-built aircraft operating in the experimental category are not required to have them.
After the crash, Mr Stokes was described as a passionate aviator who was a "lovely fellow and a brilliant engineer, and an excellent pilot".
He had spent four years and $250,000 building the three-quarter-scale Spitfire.
