Morning search plan for missing NSW plane

A search for a plane missing after it faded off the radar west of Coffs Harbour on the NSW north coast has been called off for the night.

The light plane departed Murwillumbah in northern NSW at 6.30am on Friday and was scheduled to arrive in Taree at 8am.

Police say they were told the aircraft was missing about 11.45am on Friday. Its last known communications were about 7.30am.

It's unknown how many people were on board.

The Australian Maritime Safety Authority said in a statement it was aware of the overdue Mooney M20 aircraft and had tasked the Westpac Rescue Helicopter and a search-and-rescue jet with the search.

They were looking about 27 kilometres inland from Coffs Harbour, AMSA said, but cloudy weather conditions had complicated the search effort.

AMSA on Friday evening said it had called off the search for the night and would resume at first light, though weather conditions were likely to be similarly poor.
