Narrative:
During take-off from the Helitours heliport located near Guatapé, Antioquia, the Robinson 44 helicopter with registration HK-4449 hit the main rotor blades against the tail of the aircraft, causing structural damage.

As a result of the event, the aircraft suffered significant damage; however, no injuries to any of its four (4) occupants occurred. There was no post-impact fire.
The accident occurred in daylight and VMC weather conditions.
The investigation determined that the accident was due to the following probable causes:
