What happened
On March 17, 2026, at approximately 11:15 local time, a Robinson R44 II helicopter, registration LV-GFK, was involved in an accident during the takeoff phase of flight near San Juan, Argentina. The aircraft, operated by a private owner, was performing a non-scheduled flight with one pilot and three passengers on board. During the takeoff roll, the helicopter collided with an obstacle, resulting in the destruction of the airframe. Despite the impact, all four occupants were able to evacuate the aircraft on their own. There were no fatalities, though the aircraft was destroyed.
The investigation
The preliminary investigation focused on the circumstances surrounding the takeoff at the San Juan Aeroclub. Investigators examined the aircraft's condition, noting that the helicopter was a 2015 model equipped with a Lycoming IO-540-AE1A5 engine. The investigation reviewed the flight conditions, which were characterized by Visual Meteorological Conditions (VMC) with high visibility and daylight. The terrain at the site of the wreckage was flat and sandy, located less than 10 km from the aerodrome. The impact velocity was recorded at a low speed of approximately 5 knots, with the aircraft maintaining a level pitch and roll attitude at the moment of the event.
Findings
- The primary cause of the accident was the collision with an obstacle during the takeoff maneuver.
- Preliminary data suggests that the Maximum Permissible Mass (PMD) may have been exceeded during the flight preparation.
- Discrepancies in loadsheet calculations or weight and balance management are being considered as a contributing factor.
- The aircraft's structural integrity was compromised, leading to the total loss of the airframe.
