Brief

Occurrence Briefs are concise reports that detail the facts surrounding a transport safety occurrence, as received in the initial notification and any follow-up enquiries. They provide an opportunity to share safety messages in the absence of an investigation.

What happened

On 15 January 2018, at 1245 Eastern Standard Time (EST), a Vans Aircraft RV-7A commenced take-off from runway 15 at Atherton airport, Queensland (Qld) for Charters Towers, Qld. The pilot was the sole occupant.

The pilot reported that upon rotation,[1] the aircraft encountered a dust devil[2] and was pushed to the left. The pilot then applied full power in an effort to regain directional control and land the aircraft. The left wing, however, contacted the ground, and the aircraft came to rest inverted. The aircraft was substantially damaged and the pilot received minor injuries.

A row of trees to the left of the runway combined with hot weather was conducive to the formation of dust devils. There was no visual indication of debris or dust plumes to indicate the sudden formation or location of the dust devil, causing difficulty in identification and avoidance measures.

Further information on The Dangers of Dust Devils is available on the ATSB website.
