He's a bloody hero.

That's from the brother of a Kaikoura pilot, prosecuted for rescuing an injured hunter while suspended from flying.

Dave Armstrong is being prosecuted by the CAA after he flew rescue teams and a doctor into remote bush last April.

He'll appear in court on Friday.

Tim Armstrong said his bother has admitted his mistake and shouldn't be facing a prison sentence.

He said it's taken a huge toll on him but those involved may have died if Dave hadn't stepped in.

Armstrong said Dave told him he's out options after battling for a long time.

 

A petition calling for the charges to be dropped has already gained over three-thousand-signatures.
