What happened

On 16 June 2017, a Pacific Aerospace Limited FU24 Stallion, registered VH-EUO, was conducting aerial agricultural operations from an airstrip 40 km north‑east of Bathurst, New South Wales. The purpose of the operations was to apply fertiliser and seed to private grazing land.

At about 1405 Eastern Standard Time,[1] the aircraft took off from the airstrip for the second flight of the second job of the day. When the aircraft did not return as expected, the loader raised the alarm and a search for the aircraft commenced at approximately 1600. Early the next morning, the wreckage of the aircraft was found in dense scrubland to the east of the application area. The pilot received fatal injuries as a result of the collision with terrain.

What the ATSB found

The ATSB found that shortly after the end of the third application run, the aircraft was flown into an area of rising terrain that was outside the normal operating area for that job site. While subsequently repositioning the aircraft for the fourth application run, it was likely that the aircraft aerodynamically stalled leading to a collision with terrain. Based on the available evidence, it was not possible to determine the reason for the loss of control.

Additionally, there was no evidence of any in-flight failure of the airframe structure or flight control systems. The engine appeared to have been producing significant power at impact.

Safety message

Operators and pilots are reminded of the dangers of aerial application near rising terrain and the importance of pre-flight planning of application runs to account for nearby terrain. Although it could not be established that not dumping the hopper contributed to this accident, in an emergency, reducing the aircraft’s weight by dumping the hopper load will optimise an aircraft’s flight performance.

The Aerial Application Association of Australia (AAAA) have published strategies in their pilot’s manual. With regard to the dumping of the load, the manual states ‘The only safe rule is ‘if in doubt, dump’.’
