All Boeing 777 jetliners to be checked in US after Denver incident

The US Federal Aviation Administration (FAA) has demanded to check all Boeing 777 jetliners powered by a particular Pratt & Whitney engine model, Report informs, referring to the FAA Twitter page.

"This will likely mean that some airplanes will be removed from service," the FAA tweeted.

Soon after United Flight 328 departed Denver for Hawaii on Feb. 21, the right engine failed, shedding debris across three neighborhoods before the plane returned safely to Denver, according to the authorities. None of the 229 passengers or ten crew members were injured.

The NTSB said that an initial investigation showed that two fan blades in the plane’s Pratt & Whitney PW4077 engine had fractured and that the cowling, or covering, had separated from the engine. Investigators are examining the engine and airplane as well as photographs and videos taken by passengers. The cockpit voice recorder and flight data recorder were taken to Washington for analysis.
