UK lifts ban imposed on Boeing 777 with PW4000 engines


The UK’s Civil Aviation Authority (CAA) has lifted the ban imposed on the Boeing 777 aircraft fitted with Pratt & Whitney 4000 engines.


Several airlines grounded the aircraft with the specific engine type while the UK banned the aircraft from flying in their airspace following the United Airlines 777-200 engine problem on 23rd February 2021 that gained global attention.


In the case of United 777, the engine's inlet separated with an engine failure after takeoff. The FAA then issued an Emergency Airworthiness Directive (EAD) which required immediate inspections of the Boeing 777 aircraft with certain PW4000 engines which led to the grounding of the aircraft.


According to Boeing, 69 777 jets were in service at that time which is powered by the same engine, while 59 such aircraft are in storage.
