Air ambulances grounded over safety fears will begin flights again on Wednesday.
The Scottish Ambulance Service's two Eurocopter EC135s, based in Inverness and Glasgow, were taken off duty on Tuesday.
They were among 22 models of the same aircraft, including 16 air ambulances across Britain, suspended as a precaution by operator Bond Air Services.
The measure was taken following the discovery of a fault in one of the Scottish air ambulances last month.
A crack was discovered on the main rotor hub, prompting a safety warning by the European Aviation Safety Agency (Easa).
Bond said flights would resume from 7am on Wednesday after discussions with manufacturer Eurocopter.
Earlier Bond said Eurocopter had advised pre and post-flight checks after the fault was discovered but that Bond had decided to halt flights as a precaution until further notice on safety grounds.
Around 1000 EC135s are in use around the world, including air ambulance services in England, Scotland and Wales.
Bond Air Services said it took the decision to resume flights after receiving "an unequivocal guarantee" from Eurocopter that the EC 135 was safe to fly.
A company spokesman said last night: "Over the last 34 hours, Bond Air Services has worked intensively with Eurocopter's programme engineers to determine if the fleet can be flown safely.
"Eurocopter's team have developed a deeper understanding of the strength and the stress levels present within the rotor hub and have shared the information with UK CAA and EASA.
"As a result of this intensive engineering analysis, Eurocopter has given an unequivocal guarantee that the EC 135 is safe to fly within normal operational limits following the continuing practice of visual inspections prior to each flight."
He added that investigation of the problem would continue in order to find a permanent solution.
