Man dies after NSW ultralight crash

A pilot seriously injured in a western NSW crash that "completely destroyed" his ultralight aircraft has died in hospital.

It's believed the 35-year-old was preparing to land on a farm about 50km south of Ivanhoe, almost 400km east of Broken Hill, when he crashed on Friday morning.

"The plane was completely destroyed ... and will be examined by investigators," police said in a statement.

It's believed the man was using the ultralight to muster stock.

He was initially treated at the scene by paramedics for serious head, leg and ankle injuries before being taken to Ivanhoe Health Service but later died.

Police will prepare a report on the crash for the coroner.
