A Red Wings Yakovlev Superjet 100 caught fire at Yekaterinburg’s Koltsovo Airport while being prepared for a flight to Magnitogorsk, after smoke appeared in the avionics compartment during oxygen cylinder filling for the crew. One technician was injured and taken to hospital, while the four crew members left the aircraft unharmed. No passengers were aboard at the time, and the jet was grounded for inspection.
The incident happened during preflight servicing on the ground, limiting the risk compared with an in-flight emergency. The aircraft was undergoing routine preparation when the fire or smoke event developed in a technical area near the avionics compartment, underscoring the hazards linked to ground handling and servicing operations at busy airports.
The final cause of ignition has not been established, and the extent of any damage to the Superjet has not been disclosed. No formal statement on the investigation or possible regulatory response had been reported in the initial coverage. The aircraft remains out of service pending evaluation.
