The first wholly-owned helicopter to join the Midlands Air Ambulance fleet will be unveiled today - as the charity cuts the ribbon on its new airbase at RAF Cosford in Staffordshire.
The £4.5 million EC135Te helicopter is the first to be owned in full by the service, with all previous machines leased from Bond Air Services.
At a celebration event today, the Air Ambulance will also launch an appeal to raise £250,000 towards extending the service's winter flying hours.
Currently, the choppers only fly during daylight hours - but the extra cash will help keep them in the air for 12 hours a day.
The Midlands Air Ambulance Charity is appointing a number of Midlands sport players, Olympians and Paralympians as ambassadors later.
Among those is former Leicester Tigers captain and England World Cup-winning forward Neil Back and Paralympic Gold and Silver medalist Mickey Bushell, from Shrewsbury.
All three West Midlands air ambulances have resumed to normal services following their suspension.
The West Midlands Ambulance Service (WMAS) ground the three aircraft on Thursday after tests raised concerns over their EC 135 helicopters - the same which crashed into The Clutha bar in Glasgow on 29 November, killing 10 people.
WMAS has confirmed all three helicopters have resumed service "following extensive inspections by engineers from Bond Air Services."
Two of the three helicopters used by the Midlands Air Ambulance remain grounded today as inspections continue.
The entire fleet was grounded by the company which operates its EC-135 craft after a fault was found in another model.
One of the choppers, based at Tatenhill airbase in Staffordshire, was cleared for flight on Thursday by engineers from Bond Air Services - but the other two, based at Cosford and Strensham, are still being examined.
It is hoped they will return to service tomorrow.
West Midlands Ambulance Service spokesman Steve Parry said:
Safety is our highest priority and we will be guided by the operator of the aircraft.
Medical crews that would normally have been flying have been responding on land vehicles as they would if inclement weather had stopped the helicopters operating.
One of the three helicopters used by the Midlands Air Ambulance has been cleared to return to normal service this morning.
The fleet was grounded yesterday by operator Bond Air Services after a fault was discovered in one of the models elsewhere in the country.
But, after an inspection by Bond engineers, the chopper based at Tatenhill airbase in Staffordshire will take to the skies again today.
Inspections on the other craft, which are based at Cosford and Strensham, are continuing.
A West Midlands Ambulance Service spokeswoman said:
Clearly safety is our number one priority and will be guided by the operator of the aircraft.
The crews that would have been flying today have been responding on land vehicles as they would if the weather had stopped the helicopters flying.
East Anglia air ambulances have returned to service after helicopter operator Bond Air Services suspended a number of flights over a "defect" in one aircraft.
Bosses at the Midlands Air Ambulance have vowed rescue services will continue - despite being limited to land ambulances.
Speaking after the charity was forced to suspend its air rescue service following a fault with a similar model, chief executive Hanna Sebright said:
A spokesperson for the Department of Health said that patients should not be affected by the grounding of air ambulances:
The partial suspension of the UK's air ambulance fleet is due to a discovery of a technical fault discovered on one, the Association of Air Ambulances said.
