BERLIN, April 2. /TASS/. There are no primary leads yet of the crash of a private plane in western Germany, in which head of S7 Group’s Board of Directors Natalya Fileva was killed; they will appear only after the publication of an interim report, the German Federal Bureau of Aircraft Accident Investigation (BFU) and prosecutors told TASS on Tuesday.

"It is too early to speak about any possible reasons: no leads are being studied as a priority," the agency’s official said. Experts are still working on the incident site - near Frankfurt Egelsbach Airport (the German state of Hesse). "As I earlier said, only after that the analysis of the gathered materials will start and the first findings will be made in an interim report," he noted. This report will be ready in 1.5-2 months.

Mass media earlier reported, citing sources, that a pilot’s mistake is the major lead.

Darmstadt's prosecutors, who are also investigating the incident, did not confirm this information either. "It is too early to name any major leads; I cannot say anything on this account," an official for the public prosecutor’s office told TASS.

On Sunday, an Epic business jet en route from Cannes crashed near Frankfurt Egelsbach Airport. Three people were on board, according to S7’s press service, head of S7 Group’s Board of Directors Natalya Fileva among them. The German side did not officially disclose the names. The autopsy is scheduled for Tuesday, and the results will be announced on Wednesday.
