A regional division of the Russian Ministry of Emergency Situations reported the landing on its website. The airport’s director had alerted the emergency services because “an instrument light activated for failure of the control channel for the left engine.”

The plane was being operated mostly as a cargo flight, carrying 36 metric tons of cargo and 25 people, the report said. “The aircraft landed safely and nobody was harmed,” it said.

It was unclear whether the engine indeed malfunctioned or the instrument light activated incorrectly. The Russian report also did not clarify whether the pilots shut down the engine before landing.

Boeing said on Sunday that all 128 of its 777 jetliners equipped with Pratt & Whitney engines of the type involved in the Colorado incident, the PW4000 series, would be grounded worldwide. The 747 involved in the accident in the Netherlands was powered by a different type of Pratt & Whitney engine.

Pratt & Whitney engines were also the focus of concern in an episode in December when an engine problem forced a Japan Airlines plane to turn around shortly after taking off from Okinawa.

Rossiya Airlines is part of the national flag carrier, Aeroflot, and like its parent company operates a fleet of mostly Western-made planes. It flies 10 Boeing 777 airplanes, according to the airline’s website. Boeing and Rossiya Airlines did not immediately return calls asking for comment about the incident.
