Authorities have confirmed that the pilot of a plane that crashed while fighting bushfires west of Ulladulla has died.

David Black, 43, a husband and father-of-three from Trangie in central NSW, was waterbombing when his plane crashed in rugged bushland on Thursday morning.

Shoalhaven local area commander Superintendent Joe Cassar said an ambulance officer had been winched into the remote area where the crash occurred and confirmed Mr Black was dead.
