This accident clearly demonstrates the need to check off each element of the safety system, in this case:

  • obtaining all relevant information about the local conditions, including wind direction and strength, prior to commencing an approach to an aerodrome.
  • conducting a standard approach, which enables assessment of the environmental and runway conditions and allows checks to be completed in a predictable manner.
  • initiating a go-around promptly, and ensuring the aircraft is correctly configured.

The ATSB concluded that the causes of the accident were multiple. These were:

  • the selected approach direction exposed the aircraft to a tailwind that significantly increased the groundspeed on final approach and resulted in insufficient landing distance available.
  • the final approach path was not stable. In combination with the tailwind, that resulted in the aircraft being too high and fast with a bounced landing well beyond the runway threshold.
  • the go-around was initiated at a point from which there was insufficient distance remaining for the aircraft to climb above the tree at the end of the runway in the landing flap configuration and tailwind conditions.

This accident highlights the reasons why it’s so important to remain aware that for an accident not to happen, all elements of the system must be considered, actioned and confirmed in place.
