Kernrechtsfrage
Whether the administrative appeal against the denial of helicopter registration and airspace authorization was admissible.
Extrahierter Entscheid
The appeal was inadmissible because the challenged decision concerned authorization of a vehicle whose grant depended essentially on technical characteristics; Art. 99(1)(e) OG barred administrative appeal.
Extrahierte Begründung
The helicopter is a vehicle (aircraft). Both registration-based admission and special authorization under the Aviation Act depend on the aircraft's technical condition. The air-transport exception in Art. 99(1)(e) OG applies only to installations, not vehicles.
