The Rossiya Air flight was operating as a cargo service from Hong Kong to Madrid, according to an employee at Sheremetyevo International Airport, who declined to be named. Neither Boeing nor Rossiya Air were immediately available for comment.

The crew of the plane requested to make the emergency landing after one of the left engine control channels failed, according to Interfax. No injuries were reported. The type of engine wasn’t immediately clear.

Last Saturday’s incident in Colorado involved a PW4077 engine made by Pratt & Whitney, a division of Raytheon Technologies Corp.

A preliminary examination of fragments from the engine suggested a crack that grew gradually over time prompted the failure. The incident led to groundings of all the Boeing 777s around the world that use the engine.

Meanwhile, Cathay Pacific said they have no Boeing 777s equipped with the PW4077 engine made by Pratt & Whitney, nor did they run routes between Madrid and Hong Kong.
