P&W engine disintegrates mid-flight on United Airlines...
So America is also now "sabotaging" Boeing since the plane that had an emergency landing in Hawaii due to damaged engine was a B777?

The new 777X is powered by GE turbofans. These old 777s ended production last year.So America is also now "sabotaging" Boeing since the plane that had an emergency landing in Hawaii due to damaged engine was a B777?
That particular United Air B777 that did an emergency landing in Hawaii was powered by PW4000.The new 777X is powered by GE turbofans. These old 777s ended production last year.
Pratt & Whitney’s planned engine deliveries for the full year remain unchanged despite a part failure that could hold up engine deliveries to the geared turbofan’s largest customer until April.
On 9 February, the European Aviation Safety Agency issued an emergency airworthiness directive after preliminary findings indicated that the root cause of four recent engine shutdowns was a recent durability improvement to the aft hub knife edge seal in the high pressure compressor. Six days later, the US Federal Aviation Administration published the same warning.
Both notices identified a batch of nearly 100 engines that Pratt & Whitney had delivered to Airbus, including 43 already operating in service.
Airbus and P&W have submitted a mitigation plan to the regulatory authorities. If the latter approve, Airbus expects deliveries from P&W to resume in April.
The latest problem follows a familiar theme with the GTF. P&W packed the engine with several advanced technologies, including a fan drive gear system, hybrid-metallic fan blades and a sophisticated cooling system for the turbine blades. Despite the industry’s experience with such technologies, the most innovative parts of the GTF have not raised complaints about performance, although P&W acknowledged struggling with the manufacturing yields for the hybrid metallic blades.
Grounded 30% of the fleet, stopped deliveries for at least two months, crashed the stock $3 billion and will allow Boeing to compete on deliveries. Sabotage is clear, the only question is whether it is intentional.Sabotage my a$$!
