What happened
In the early hours of 22 June 2025, a Robinson R44 Raven II helicopter, registration ZS-HFH, was engaged in an urgent agricultural mission at Metsi Berries Farm in the Modimolle-Mookgopong region of Limpopo. The flight was initiated after a farm manager received an automated alert indicating that temperatures in the blueberry fields had dropped below freezing, threatening the crops with frost damage. The mission required the helicopter to fly low over the fields to use rotor downdraft to distribute warmer air.
Following a pre-flight inspection that showed no mechanical anomalies, the pilot took off from the farmstead. However, shortly after departure, the aircraft veered south-easterly, away from the intended target area. Within two minutes of liftoff, the aircraft disappeared from view behind trees, followed by a loud impact. The helicopter was discovered by the farm manager submerged in a flooded ditch approximately 600 metres from the departure point. The pilot sustained fatal injuries, and the aircraft was destroyed.
The investigation
An investigation by the SACAA AIID examined the circumstances leading to the loss of control. Investigators reviewed the aircraft's maintenance history, finding that the Robinson R44 Raven II had been properly maintained and was in compliance with all airworthiness directives. The engine and flight controls were also inspected post-accident, with no mechanical failures identified that would have prevented normal operation.
Regarding the pilot, the investigation confirmed a valid Commercial Pilot Licence and a Class 1 medical certificate. However, the inquiry uncovered significant irregularities regarding flight records. Investigators discovered that the pilot lacked night flying recency and found evidence of falsified logbook entries and a fraudulent training certificate issued by the operator to simulate a proficiency check that had never occurred.
Findings
- The primary cause of the accident was the loss of control due to spatial disorientation, likely triggered by frost accumulating on the windshield, which obscured the pilot's ability to maintain visual references in the dark, moonless conditions.
- The pilot did not have recent experience in night operations.
- The investigation identified a lack of adequate pre-flight planning.
- Evidence of fraudulent documentation was found within the operator's records regarding pilot training compliance.
Safety action
- It is recommended that the Director of Civil Aviation pursue enforcement action against the check pilot and operator regarding the illegal issuance of a false proficiency certificate.
