Air safety investigators are still unable to determine why the pilot of the Cirrus light aircraft which crashed in a Gundaroo paddock on October 6 killing all four people on board was unable to deploy the "last resort" parachute.
The Australian Transport Safety Bureau has released a preliminary report on the crash which found that the single-engined aircraft had "low or no power" at impact and that key components of the airframe parachute system were all located in the wreckage.
