Accident
King Air VH-AAV was operating as Advance Airlines flight DR4210 to
As VH-AAV continued to turn towards the runway, it descended to just a few feet above the water on a heading towards a sea wall enclosing the runway which stretches into Botany Bay. This manoeuvre prompted the tower controller to enquire if the approach and landing would proceed as normal. The reply from the pilot eight seconds later was "Alpha Alpha Victor negative". This was the final transmission from the aircraft. At 1909:08, the Sydney Airport crash alarm system was activated, and the preceding Ansett 727 was instructed to expedite its landing roll and vacate the runway. At 1909:20 VH-AAV was cleared to land but this clearance was not acknowledged. At 1909:22 the aircraft impacted the sea wall six feet (1.8 m) above the waterline. The total duration of the flight was 106 seconds from brakes release to impact. Five fire fighting appliances were dispatched to the accident site and crews extinguished the fire within 10 minutes of the crash.
The initial impact caused the left wing to disintegrate while a section of the right wing, including its engine, separated from the aircraft and came to rest adjacent to the runway. The fuselage was engulfed in an explosion caused by fuel igniting as the wing structures separated. The main wreckage bounced over the sea wall and landed inverted on a taxiway, sliding along the ground for a distance of approximately 55 m (180 ft). All 13 aboard the aircraft were killed in the accident which was ruled to be non-survivable.[3]
Investigation and aftermath
The accident had a profound impact upon the community in the small country town of Temora, as all 12 passengers killed were residents of the surrounding districts. The victims included a local police officer, his wife and one-week-old son who had been airlifted to Sydney five days before the accident as he required urgent medical treatment for a respiratory condition. The family were returning home aboard flight 4210.
The initial accident investigation was conducted by the Air Safety Investigation Branch of the Department of Transport and its report was released in September 1981. While this investigation could not conclusively determine the cause of the accident, a number of conclusions were made about the events leading to the crash. These included the aircraft being heavier than the maximum allowable weight by some 128 kg (282 lb) at the time of departure due to a company procedure of using standard (estimated) passenger weights. An amendment had been made to the company's Operations Manual, advising pilots to use a reduced power setting for takeoff to reduce wear on the aircraft engines, but this amendment was not approved by the Department of Transport. When combined with the ambient temperature of 39 °C (102 °F) and an overweight aircraft, these factors adversely affected the single pilot's workload and reduced the single-engine performance of the King Air to a critical extent. The investigation determined that the left engine had likely failed due to water contamination of the aircraft's fuel tanks but the source of the contamination was not established.[3]
A board of inquiry, headed by Sir Sydney Frost, was convened on 1 December 1981, sitting over 90 days.[5] On 27 January 1982, the board heard evidence from a former chief pilot of Advance Airlines who told the inquiry that on days when the temperature exceeded 28 °C (82 °F) (such as the day of the accident), it would be necessary to use a higher power setting than that advised in the company Operations Manual, and that in his interpretation of the manual this was quite clear. He also told the inquiry that Advance Airlines checked for water in the fuel system each time the aircraft was refuelled. When he operated the aircraft on scheduled flights the day prior to the accident, the aircraft performed "quite well".[6] In 1983, the board of inquiry published its findings, attributing the accident to pilot error and the presence of water in the fuel tank, leading to the engine failure. The board of inquiry recommended that commercial aircraft operating in Australia with more than nine passengers should be operated by two pilots. This recommendation was implemented by the Australian aviation regulator.
