The co-owner of Russia’s second largest airline S7 was killed when the private aircraft she was travelling in crashed in Germany.
Natalia Fileva was the major shareholder in S7, a member of the British Airways-backed Oneworld alliance.
She was one of the richest women in Russia, with wealth estimated at $600 million.
The Epic LT single-engine turboprop aircraft with two passengers and a pilot on board was en route from Cannes in France when it came down near Frankfurt Egelsbach airport and caught fire on Sunday.
“The S7 Group holding team expresses deepest condolences to the family and significant others,” the company said.
Russian and international authorities would investigate the crash, S7 added.
