On 22 October 2010, a replica Supermarine Spitfire MK26 recreational/light sport aircraft (registered 19-4024) collided with terrain near Gympie authorised landing area (ALA), fatally injuring the pilot. Recreational Aviation Australia Inc (RA-Aus) is assisting the Queensland Police in their investigation of the occurrence.

On 17 November 2010, RA-Aus requested technical assistance from the Australian Transport Safety Bureau (ATSB) for the recovery of data from an engine management system (EMS) module recovered from the accident site. To protect the information supplied by RA-Aus and the investigative work undertaken, the ATSB initiated an investigation under the Transport Safety Investigation Act 2003.

Due to the damage to the EMS and the lack of configuration information, the recovery involved extracting the data from the electronic memory components and, using example data provided by the EMS manufacturer, converting the binary extracted data into engineering units.

The full converted data set was provided directly to RA-Aus investigators. This report represents an outline of the process undertaken and a summary of the data obtained.



Released in accordance with section 25 of the Transport Safety Investigation Act 2003.
