Russia’s airline regulator said it was suspending flying certificates for Boeing 737s in use in the country until it receives notification that the planes are safe to fly.


The statement by the country’s Interstate Aviation Committee (IAC), dated 4 November, did not immediately ground flights. A spokesman for Rosaviatsia, which is obliged to comply with IAC safety recommendations, said it had not been notified, so there was no order yet to suspend flights.


There are about 200 Boeing 737s in Russia, according to Reuters calculations based on data from Rosaviatsia, or about a fifth of a total fleet, both passenger and cargo.


“Over 95% of all foreign aircraft operated in Russia and accounting for over 85% of all passenger flights, including Aeroflot, are registered and are in the registers of foreign countries,” IAC said.
