MOSCOW, July 7 (RAPSI, Oleg Sivozhelezov) - Patrick Vervel, the husband of a stewardess, who died in the Total CEO airplane crash in 2014, has filed a lawsuit with a Moscow court seeking to recover 30 million rubles (about $500,000) from Russia’s Vnukovo airport, lawyer Alexander Sergeyev told RAPSI on Friday.

On Friday, the Solntsevsky District Court of Moscow began hearing the case against snow plow driver Vladimir Martynenko and Vnukovo lead airfield service engineer Vladimir Ledenev, who had earlier pleaded guilty and signed a plea bargain.

Martynenko and Ledenev are charged with violation of traffic safety rules resulted in the death of two or more persons. The widow of Total CEO Cristophe de Maergerie, relatives of the deceased flight crew members, Vnukovo airport and Unijet air carrier have been recognized as victims in the case.

Earlier, the Moscow City Court upheld the ruling to send a case against other defendants, airport flight manager Roman Dunayev, air traffic controllers Alexander Kruglov and Nadezhda Arkhipova, back to prosecutors.

Christophe de Margerie died in a plane crash at Vnukovo airport on October 21, 2014, when his plane’s wing hit a snow plow. Among the victims were three crew members, all French citizens.

On October 25, 2016, the Interstate Aviation Committee (IAC) published its final report on investigation into the death de Maergerie. Authors of the report listed several factors, which, when combined, may have resulted in the plane crash. Among potential causes of the crash are: violation of regulations over control of alcohol use by drivers of special equipment, absence of equipment for listening to traffic controllers in snow plow machines, inefficient organization of work with subsystem of observation and control of airfield, no measures taken by the plane’s crew to prevent takeoff after receiving information about “machine that intersects a road”.
