The parents of a newlywed groom who was among five Britons to die a helicopter crash in the Grand Canyon are suing the tour operator in a wrongful death lawsuit.

Jonathan Udall, who died in hospital days before his wife Ellie Milward, could have survived if Papillon Grand Canyon Helicopters and manufacturer Airbus Helicopters had not negligently failed to install a crash-resistant fuel tank, according to the lawsuit filed on Friday.

The honeymooning couple died in hospital as a result of burns sustained in the February 10 crash that killed their friends Becky Dobson, her boyfriend Stuart Hill and his brother Jason Hill.

Lawyers for Philip and Marlene Udall, of Southampton, claim in the lawsuit filed in Nevada that their 31-year-old son would not have sustained "severe and catastrophic" burns if the Airbus EC130 B4 had been fitted the fuel system.

After the lawsuit was filed, lawyer Gary Robb said: "Mr and Mrs Udall deeply grieve for the loss of their son but their primary motivation now is to prevent anyone else from having to suffer the deadly burn injuries as their son did.
