Following the United Airlines 777 suffering engine failure shortly after departing Denver Airport and a number of similar incidents in the past Boeing and engine manufacturer, Pratt and Whitney have recommended the temporary grounding of 128 Boeing 777 aircraft which operate using the PW4000-112 engine.
Out of the 128 aircraft, 69 are currently in service, with a further 59 in storage. This recommendation comes after an incident with a Pratt and Whitney 1400-112 engine where it caught fire. The cause of the fire is still unknown.
In a press release made released by Boeing, the company said “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.”
