THE Wiltshire Air Ambulance has been temporarily grounded following an incident at its new £5 million airbase near Semington.

The Civil Aviation Authority confirmed they are looking into an incident last Friday evening at the new airbase at Outmarsh Farm.

It’s understood the engine of the Wiltshire Air Ambulance aircraft spun out of control at high speed while the air crew were performing routine maintenance check on the helicopter.

A critical care medic, stood outside the aircraft while the checks were being carried out, was fortunate not to suffer any injuries despite nearly being hit by the helicopter.

It’s not clear how long the aircraft will be out of action, but it’s not expected to be flying again until next week.

For now, critical care medics will respond to serious incidents with rapid road response vehicles.

A Wiltshire Air Ambulance spokesman said: “Yes, there was an incident last Friday evening with the helicopter, it occurred during a routine engine ground run. This is part of the daily engine power assurance checks.

“Nobody was hurt, there was no damage to the helicopter, building or equipment.

“We are awaiting the arrival of a spare component to release the aircraft back into service. Following engineering testing, we expect the helicopter to be online again early next week.

“The CAA were informed, as this is normal procedure and are supporting us where required. No further action is expected.

“We are still operational, covering our area and assisting neighbouring air ambulances with rapid response vehicles as we regularly do.”

The Air Accidents Investigation Branch confirmed the incident was being investigated by the Civil Aviation Authority.

A CAA spokesman said today they were aware of the incident but were not able to provide any further comment until next week.
