Update...
The reason the pilot elected not to use the existing helipad was because there was a chain around it that had not yet been removed by the resort ground staff there. The brown out occurred on take off, not landing. There were six passengers on board, all of whom made it out with no serious injuries. The aircraft which had been used operationally for only 1 week is a write-off. The GCAA (UAE aviation authorities) are investigating.
