Fatal Terrain Collision During Low-Level Survey Flight

1 fatality • 124 km west of Norseman, Western Australia

A Cessna U206G crashed into terrain during a geophysical survey, resulting in the death of the pilot and highlighting significant gaps in emergency response and risk management.

What happened

On 3 March 2022, a Cessna U206G, registration VH-JVR, was performing a low-level geophysical survey when it struck trees and was destroyed by a post-impact fire. The accident occurred while the aircraft was on its 25th survey line. The impact was characterized by a steep, nose-down attitude and a left bank, suggesting a loss of control. The pilot sustained one fatality.

The investigation

The ATSB examined the wreckage and flight data to determine the cause of the crash. Investigators found that the engine was producing power and the aircraft remained structurally intact until impact. There was no evidence of bird strikes, mechanical failure, or pilot impairment due to health or substances. While the aircraft's airspeed remained above stall speeds during previous turns, the investigation noted that the procedure turns were performed at altitudes too low to allow for recovery from a stall.

Furthermore, the investigation looked into the delay in the emergency response. Although satellite tracking data ceased at 1343, the operator's automated alert system failed to notify them because a specific watch function had not been activated. The ground operator did not notice the loss of signal until 1430. Because the pilot was not wearing the personal locator beacon carried in the aircraft, its location was not immediately known. The operator did not contact the Joint Rescue Coordination Centre until 1701, approximately three hours after the initial loss of tracking.

Findings

  • The aircraft was likely maneuvering to intercept a new survey line when control was lost at an altitude insufficient for recovery.
  • The operator's risk management processes lacked pre-operational assessments and a formal risk register.
  • Flight procedures for steep turns (45°–60°) were not specifically detailed in the operations manual, leading to potential inconsistencies in safety margins.
  • The emergency response was delayed because the satellite tracking system's automatic alert function was not active.
  • There was no requirement for pilots to wear protective clothing or helmets, which could have improved survivability.

Probable cause

The aircraft likely experienced a loss of control during a maneuver to intercept a survey line at an altitude that precluded recovery, leading to the collision with terrain.
