United Airlines has made this announcement:
We are voluntarily and temporarily removing 24 Boeing 777 aircraft powered by Pratt & Whitney 4000 series engines from our schedule. We will continue to work closely with regulators to determine any additional steps and expect only a small number of customers to be inconvenienced.
The remaining 28 are already in storage.
The United announcement came after the FAA issued an emergency order saying it would be increasing inspections of Boeing 777-200s equipped with Pratt & Whitney PW4000 engines.

“The Pratt & Whitney PW4000 is a family of high-bypass turbofan aircraft engines produced by Pratt & Whitney as the successor to the JT9D . It was first run in April 1984, was FAA certified in July 1986, and was introduced in June 1987. With thrust ranging from 50,000 to 99,040 lbf (222 to 441 kN), it is used on many wide-body airliners.”
