Investigator Anders Flanking will present his proposals to the government on Wednesday.
The nine airports the state should take over are Arvidsjaur, Gällivare, Halmstad, Jönköping, Kalmar, Skellefteå, Stockholm Skavsta, Sundsvall and Örebro.
More airline routes than today should also be subject to public service obligations. And if commercial air traffic is significantly reduced or ceases, the state should procure more air service, he suggests.
There will be no proposal regarding Bromma's future.
"We should see how scheduled flights and electric flights develop, to take a couple of examples, before taking a definitive position," says Anders Flanking in a press release.
