Aeronautical Engineers, Inc. (AEI) has redelivered the first B737-800SF converted freighter to Sofia-based CargoAir in Bulgaria. This aircraft also represents the first AEI B737-800SF freighter conversion to be operated in Europe.

AEI received EASA approval for the B737-800SF earlier this month.

In November of last year, CargoAir signed up for two AEI B737-800SF freighter conversions, after cancelling an agreement for two B737-800BCFs.

The second AEI B737-800SF freighter conversion for CargoAir will commence modification in June and will be performed by the authorized AEI conversion center, Commercial Jet in Miami, Florida
