On May 15th 2019, about 13:00, an EC135 P2+ was damaged by having a hard landing during an aerial exercise near Arouca, Trinidad. Due to the fact, that there was no FDR available, the flight data could be reconstructed using the iwi® methodology based on an available video recording of a witness, which filmed the accident. In addition to the flight path, vertical speed, groundspeed, as well as the helicopter attitudes could be reconstructed, supporting the accident investigation to clarify the root cause.
