After Saturday’s engine failure on United Airlines flight UA328, the Federal Aviation Administration issued an emergency airworthiness directive that requires “immediate or stepped-up inspections of Boeing 777 airplanes equipped with certain Pratt & Whitney PW4000-112 engines.” Boeing has told airlines to stop flying the 69 in-service and 59 in-storage 777s equipped with the engine.

As a result, airlines operating PW4000-112 powered Boeing 777s have grounded them in the US, Japan and South Korea.
Pratt & Whitney: “United Airlines Flight 328 is currently under NTSB investigation and Pratt & Whitney has dispatched a team to work with investigators. Pratt & Whitney is actively coordinating with operators and regulators to support the revised inspection interval of the Pratt & Whitney PW4000 engines that power Boeing 777 aircraft. Any further investigative updates regarding this event will be at the discretion of the NTSB. Pratt & Whitney will continue to work to ensure the safe operation of the fleet.

“Boeing is actively monitoring recent events related to United Airlines flight 328. While the NTSB investigation is ongoing, we recommended suspending operations of the 69 in-service and 59 in-storage 777s powered by Pratt & Whitney 4000-112 engines until the FAA identifies the appropriate inspection protocol. Boeing supports the decision yesterday by the Japan Civil Aviation Bureau, and the FAA’s action today to suspend operations of 777 aircraft powered by Pratt & Whitney 4000-112 engines. We are working with these regulators as they take actions while these planes are on the ground and further inspections are conducted by Pratt & Whitney. Updates will be provided as more information becomes available.” Photo: Hayden Smith.
We are voluntarily & 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.

As a reminder, on February 20th, shortly after taking off from Denver as UA328 to Honolulu, United’s Boeing 777-200 (N772UA, the 5th 777 ever built) experienced right-hand PW4077 engine failure, with parts of its falling to the ground. There were 231 passengers on-board and 10 crew. The pilots did not dump fuel and declared “Mayday”. After stopping the climb at 13,000 feet, the pilots requested to return to Denver, where the 777 landed safely 23 minutes after departure. A replacement Boeing 777-200 took the passengers to Honolulu with a 6h delay. NTSB has opened an investigation.
NTSB has released photos with the damage suffered by United's Boeing 777-200 (N772UA) after the right-hand engine…

As an update, Korean Air said it has grounded its 777s with P&W engines. And Asiana also confirms the same about its nine P&W-powered 777s.
