Preliminary Report Released 20 May 2010
On 28 March 2010, a Piper Aircraft Corp PA-30 Twin Comanche, registered VH-KDS, departed from Jandakot Aerodrome, Western Australia for a private flight under the visual flight rules. On board were two qualified pilots, both of whom were endorsed on the aircraft type. Following the failure of the aircraft to return to Jandakot later that day, a search was initiated to locate the aircraft and occupants. The following morning, the seriously-damaged aircraft was located and both occupants were found to have received fatal injuries.
Examination of onboard GPS information indicated that, while tracking towards Jandakot Aerodrome, the aircraft commenced a steep descent from about 3,500 ft above mean sea level that continued to ground level.
