On 13 February 2007 at 1830 Western Daylight-saving Time, a Beech Aircraft Corporation 58 Baron was being used for instrument flight training. The flight was being conducted under the visual flight rules (VFR), with the pilot flying, simulating flight under the instrument flight rules (IFR). A second pilot was on board to act as a safety pilot and to lookout for other aircraft. During the conduct of a Busselton, WA non-direction beacon (NDB) approach, the pilot flying became incapacitated and the safety pilot assumed control of the Baron. The safety pilot landed the aircraft on runway 21 at Busselton and the incapacitated pilot received treatment from attending ambulance officers. The pilot was a 22 year old, Grade 2 flying instructor, with 1,422 hours total flying experience. Following a check by a Designated Aviation Medical Examiner and 4 days rest, the pilot was approved to return to work.

The pilot stated that about 12 months previously, he had experienced a similar event and after a number of medical tests that did not find any physical problems, it was established that he had been dehydrated.

Initial medical testing following the event found no health problems and it is possible that the pilot's sustenance and fluid intake was inadequate. The pilot changed his eating and fluid intake habits, including using a water bottle while flying.

The Civil Aviation Safety Authority (CASA) Aviation Medicine section subsequently suspended the pilot's Class 1 medical and requested the pilot undergo further testing. That testing found that the pilot had epilepsy and CASA revoked the pilot's medical.
