“Based on the initial information, we concluded that the 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,” Dickson said.
Following the FAA announcement, United Airlines said in a statement that it is “immediately” removing 24 Boeing 777 planes that are powered by Pratt & Whitney 4000 series engines “out of an abundance of caution.”
The 24 aircrafts are part of the 52 777s in the United fleet. The other 28 remain in storage. The move is voluntary and temporary, United said, and should only disrupt “a small number of customers.”
This developing story will be updated.
