Devon and Cornwall Police has launched an investigation into what happened, and the woman’s next of kin has been informed.
An 87-year-old woman has died after suffering “a serious head injury” when a coastguard helicopter landed at a hospital.
She was one of two people injured as a helicopter carrying a casualty arrived on a helipad at Derriford Hospital in Plymouth.
Another woman in her 80s suffered a broken pelvis and is being treated in hospital.
Devon and Cornwall Police has launched an investigation into what happened, and the woman’s next of kin have been informed.
Detective Inspector Andy Hodges said the victim, who was 87 and on a near-by footpath at the time, was blown over by the aircraft’s down draft at around 11.20 on Friday morning.
“She sustained a serious head injury and later died in Derriford Hospital. Her next of kin have been informed and a file is to be prepared for the coroner,” DI Hodges added.
“A second woman, also in their 80s, was in the car park when it is believed the down draft caused the car door to slam shut whilst she was exiting her vehicle.
“She has suffered a broken pelvis and remains in hospital in a stable condition,” Mr Hodges said.
The aircraft, he added, “was carrying a casualty linked to a separate job earlier that morning”.
He said: “This is a tragic incident, and our thoughts go out to all affected by what took place yesterday at Derriford.”
A Department for Transport spokeswoman said: “Our deepest sympathies go out to those affected by the incident at Derriford Hospital.
“It would be inappropriate to comment while the incident is investigated by Devon and Cornwall Police and the Air Accidents Investigation Branch.”
HM Coastguard has been contacted for a comment.
The helipad was built in 2015 – and according to the Plymouth Herald, it cost £1.75m, with hundreds of patients arriving by air each year.
