Grounding of 777s urged

Chicago: Boeing Co yesterday said it recommended suspending the use of 777 jets with the same type of engine that shed debris over Denver at the weekend after US regulators announced extra inspections and Japan suspended their use while considering further action.

The moves involving Pratt & Whitney PW4000 engines came after a United Airlines 777 landed safely in Denver on Saturday (local time) after its right engine failed.

The manufacturer recommended airlines suspend operations until US regulators identified the appropriate inspection protocol.

The 777200s and 777300s affected are older and less fuel efficient than newer models and most operators are phasing them out.
