The Federal Aviation Administration said late Tuesday that the Boeing 777’s Pratt & Whitney engine would need to be inspected before the jet could fly back in the United States.
On Saturday, one of the engines ignited during a United Airlines flight, throwing debris over Colorado. This is the latest episode in which the engine family has been involved in recent years.
United announced on Sunday that it is the only American Airlines operating the Boeing 777 with the PW4000 engine series, landing 24 aircraft on its active fleet while waiting for FAA guidance. In December, a similar Pratt & Whitney engine was not installed on the 777 operated by Japan Airlines.
United said it guarantees that these 20 planes and 28 more storages will comply with FAA directives. Pratt & Whitney said in a statement that the safe operation of the fleet was a “top priority.”
Before the jets fly again, the large titanium hollow fan blades on the front of each engine must be removed and transported to the Pratt & Whitney facility for “thermoacoustic imaging” inspection according to the FAA. , High frequency vibration is applied to the fan blade, and the temperature rises. A thermal image of the blade is then recorded and analyzed for anomalous readings that may indicate potential cracks.
In 2018, a similar failure occurred on United flights involving the same plane and engine combination, and FAA began ordering engine inspections every 6,500 flights. In a statement on Tuesday, authorities said the inspection frequency could still be adjusted.
Also on Saturday, the Boeing 747, equipped with a relative of the engine, followed a similar fate and shed parts in the Netherlands. European aviation officials said they did not believe the episode was related to other failures. None of the four engine failures resulted in death. Two people have been reported to have been slightly injured in the Netherlands.
