Narrative:
The H225 (EC 225LP) with seven people aboard crashed into the sea near Dokdo shortly after takeoff from a helipad near the lighthouse atop one island. The aircraft departed at 23:25 local time having picked up an injured crab fisherman (a severed thumb). On board were two pilots, three fire department responders, the patient and a friend. Divers found the wreckage 600m offshore at 72m depth. Five bodies and some wreckage has been recovered.

Cause:
The Aviation and Railroad Accident Investigation Commission determines the cause of this accident as follows: "HL9619 crashed due to spatial disorientation of the pilot, who did not perceive the change in aircraft attitude after passing through the steep slope of Dokdo, transitioning from a bright area to a very dark sea immediately after takeoff from the Dokdo Heliport."

Additionally, the contributing factors to this accident are determined as follows:
1. The crew did not receive detailed pre-flight briefings, including mission briefings and task allocation at Dokdo Heliport, from the Central 119 Rescue Headquarters before the flight.
2. During takeoff from Dokdo, the pilot mistakenly believed that the autopilot was in G/A mode and, during the process of accelerating the aircraft, misinterpreted the strong attitude of the aircraft as a climb.
3. Mistaking the aircraft's strong attitude for a climb, the pilot continuously pushed the control stick (Cyclic), rendering the autopilot ineffective (Override), and causing an increase in speed and descent rate.
4. The pilot experienced visual illusions caused by various lights during the approach to Dokdo Heliport, which also influenced the takeoff phase.
