Aviation accident ERA19FA210

The pilots’ decision to takeoff over water in dark night conditions with no external visual reference, which resulted in spatial disorientation and subsequent collision with the water. Also causal was the pilots’ failure to adequately monitor their instruments and respond to multiple EGPWS warnings to arrest the helicopter’s descent. Contributing to the pilots’ decision was external pressure to complete the flight. Contributing to the accident was the pilots’ lack of night flying experience from the island and their inadequate crew resource management.
