The helicopter will be engaged from April 7 to 10 to transport, assemble, and disassemble the sheave batteries.

"The engagement of the helicopter ensures the efficient, safe, and timely execution of planned maintenance activities in accordance with the equipment manufacturer's recommendations and applicable technical standards," the statement said.

Residents of the surrounding areas were notified that the helicopter will use the helipad plateau at Vidikovac for landing and takeoff.
