One of Russia’s richest women died on Sunday when a private plane on which she was traveling crashed near an airport in Germany.

Natalia Fileva, 55, a co-owner of a conglomerate behind the Russian company S7 Airlines, was among three people killed when the six-seater plane crashed into an asparagus field south of Frankfurt, the German news agency D.P.A. reported.

The plane took off from Cannes, France, and crashed on Sunday afternoon while approaching the Frankfurt-Egelsbach Airport, which is south of the German city’s main international airport. The pilot was among the three victims, and the Russian news media reported that the other passenger was Ms. Fileva’s father.

In a statement, the S7 Group described the accident as “an irreparable loss.” The company said the circumstances of the crash were so far unknown, and that Russian experts would assist an international investigation.
