The measures are necessary because of an incident that took place this weekend in the US state of Colorado. A Boeing 777 was struggling with engine problems there.
Shortly after the plane took off from the American city of Denver, the engine caught fire and debris fell. They ended up in a residential area in Broomfield, a town near Denver.
No one was injured on the ground, although debris ended up in gardens and sports fields. The aircraft made a successful emergency landing at Denver airport and all occupants were unharmed.
The FAA announced yesterday that the engines of all Boeing 777s in the country must be inspected. The so-called PW4000 engine from manufacturer Pratt & Whitney should be inspected more often, an FAA spokesman explains.
The aviation authority suspects that the defect was caused this weekend due to a problem with the turbine in the right engine of the 26-year-old United Airlines aircraft.
As a precaution, the airline decides to ground all 777s. It concerns 24 devices. Meanwhile, the aviation authorities in Japan have also decided that all aircraft of this type must remain on the ground.
Last weekend, a Boeing 747 near Maastricht Aachen Airport also lost parts. As a result, a pedestrian and a child were injured. The investigation board is investigating the case, but it does not seem to be the same type of engine.
