East Wallabi Island, 31 km north Rat Island (ALA), Western Australia

On September 16, 2018, a Cessna Aircraft Company 207A (registration VH-MIA) operated by Kalbarri Scenic Flights was involved in an aviation accident near East Wallabi Island, 31 km north Rat Island (ALA), Western Australia. No fatalities were reported. Investigators recorded the probable cause as: These findings should not be read as apportioning blame or liability to any particular organisation or individual. It is likely that the aircraft landed with a tailwind component resulting in the aircraft overrunning the runway. This summary draws on records from the Australian Transport Safety Bureau (ATSB).

An aircraft overran the end of runway 36 after landing, likely with a tailwind component. The pilot's decision to land beside the taxiway reduced stopping distance. The ATSB could not determine if the pilot misread the windsock or if wind shifted.

Incident Overview

An aircraft overran the end of the runway after landing on runway 36, according to an investigation by the Australian Transport Safety Bureau (ATSB). The pilot reported checking the wind while overflying the runway to join the circuit. However, Bureau of Meteorology observations indicated a southerly wind at the time of landing, suggesting a tailwind component that may have increased ground speed.

Wind Direction Uncertainty

The ATSB was unable to clarify whether the pilot misread the windsock or if the wind direction momentarily changed when the aircraft joined the circuit and then returned to a southerly direction before touchdown. The aircraft most likely landed with a tailwind component, resulting in a faster ground speed at touchdown, which contributed to the overrun.

Landing Position and Stopping Distance

The pilot’s decision to land the aircraft adjacent to the taxiway reduced the available stopping distance. The ATSB noted that using the full runway strip would probably have allowed the pilot to stop the aircraft on the runway.

Investigation Findings

The investigation focused on the combination of possible tailwind and the choice of landing position. No other factors, such as aircraft performance or mechanical issues, were mentioned in the source. The ATSB did not assign a probable cause but highlighted these two elements as likely contributing to the overrun.
