When Sweden's regions decided to take over the ambulance flight under their own auspices, they started the Swedish ambulance flight, KSA.
They also needed their own aircraft and that became jet aircraft from Swiss Pilatus Aircraft.
The six plans cost around SEK 700 million - significantly more expensive than those used previously.
According to sources with insight into the business, the plan also consumes significantly more fuel and has major limitations.
Do not land in sub-cooled precipitation
The manual for the Pilatus PC-24 plan, which SVT Nyheter Norrbotten has seen and received confirmation from within the KSA, explicitly states that it is strictly forbidden to land or take off when airports report sub-cooled precipitation - or to fly through ice formation.
Similar prohibitions should not exist for the plans used previously.
- Having it as the only aircraft in Sweden is not appropriate, says a pilot within KSA.
18 days of icing in Kiruna - in one month
Figures from SMHI that SVT has read show what KSA can encounter for problems.
In recent years, an average of 10.4 days of freezing precipitation has been reported in December at the airport in Östersund.
When it comes to reports of ice formations, the average in December at Kiruna airport was 18 days.
This does not mean that the problems last for whole days but have been reported sometime during the day.
From specialist healthcare, there is also evidence that the new plans are not adapted to the equipment required.
Medical staff also say that they have been told to use other suppliers as KSA did not have available plans or could not handle the equipment.
