MOSCOW, August 16 (RAPSI) – Investigators will examine a bird hazard near Moscow airport Zhukovsky as part of the investigation into a Ural Airlines plane crash-landing, the Investigative Committee’s website informs Friday.

Earlier, Russia's environmental watchdog Rosprirodnadzor reported that an unauthorized dump and a garbage transfer house were found at a distance of 2 kilometers from the airport, which could decoy gulls.

Moreover, investigators are studying technical documents, the aircraft’s fuel samples and waiting for the results of the flight data recorder explanation, the statement reads.

On Thursday morning, an Airbus A-321 en route from Moscow to Simferopol crash-landed in the field shortly after departure from Zhukovsky airport. Allegedly, a flock of gulls got into the aircraft engine. According to the latest data, 76 persons out of 226 passengers were injured.

The probe was launched over alleged violation of traffic safety rules.
