Washington, Feb. 22 (BNA): The US Federal Aviation Administration said on Sunday it is issuing an emergency airworthiness directive following an engine failure in a Boeing 777.
On Saturday, a United Airlines passenger jet scattered debris over a residential area in the city of Denver, Colorado, after one of its engines failed shortly after take-off, Deutsche press agency (dpa) reported.
The FAA's new directive requires immediate or stepped-up inspections of similar planes.
FAA Administrator Steve Dickson said in a statement the directive covers Boeing 777 airplanes equipped with certain Pratt & Whitney PW4000 engines and it "will likely mean that some airplanes will be removed from service."
Dickson said the initial review of Saturday’s engine failure shows "inspection interval should be stepped up for the hollow fan blades that are unique to this model of engine, used solely on Boeing 777 airplanes."
The plane that experienced engine failure on Saturday returned to Denver International Airport safely, the FAA said. No injuries have been reported.
Flight 328 was flying from Denver to Honolulu when the incident occurred.
Police in Broomfield, a city some 48 kilometres west of Denver International Airport, shared pictures on Twitter of large pieces of debris in residents' backyards.
United Airlines told CNN there were 241 people on board, including 10 crew members.
The airline said the National Transportation Safety Board (NTSB) is investigating the incident.
