The Bell 412 helicopter, registration EC-MPL, with two pilots on board, took off at 10:57:10 from Marroxo base (Lugo) with the water bucket deployed for a fire fighting exercise. After lifting vertically, the helicopter started to move: initially maintaining a westerly course, as established in the departure procedure, but immediately after, it started a right turn in descent, following the terrain profile, during which the basket came into contact with a power line.
The investigation has determined that this contact occurred at 10:57:31, 21 seconds after the start of the takeoff, with the helicopter flying at 51 kt GS and 36 ft above the ground, leaving the helibucket with a margin above the ground of 23 ft, coincident with the height of the line. The contact produced the upward displacement of the bucket, which impacted against the left horizontal stabilizer. The consequences were minimal and, in fact, the helicopter was able to continue its flight for 23 more minutes without any incident.
The investigation has concluded that the cause of the accident was the lack of adherence to procedures, with the execution of a takeoff maneuver that failed to comply with the operating zones, trajectory, altitude and speed. The lack of information on the location of the power line in the documentation handled by the crew is considered a contributing factor.
