Russian authorities are proposing to assess airports' vulnerability to bird activity, in the wake of the Ural Airlines Airbus A321 landing accident outside Moscow.

The aircraft came down in a field shortly after departing Moscow Zhukovsky on 15 August.

Federal air transport regulator Rosaviatsia adds it is proposing to co-operate with law enforcement to "verify the legality" of waste landfills near airports – sites which potentially attract particular bird species such as gulls.

The authority states that it seeks to analyse the results of recent ornithological surveys at airports to check on the presence of facilities that "negatively affect" the bird situation in the vicinity.

Rosaviatsia will also examine the frequency of planned and unscheduled inspections of airports for the presence of birds.

All the occupants of the A321 survived the accident, which destroyed the jet, after a suspected bird-strike resulted in a loss of thrust in both engines.
