After the passenger video showing a terrifying moment where the engine on United Flight 328 to Honolulu was on fire surfaced, Boeing decided to ground all of its 777 aircraft for inspection.
The FAA has increased inspection regulations for the Pratt & Whitney 4000 series engines that each Boeing 777 is equipped with, so the 24 aircraft that were actively flying have now been removed “out of an abundance of caution.”
FAA Administrator Steve Dickson gave a statement, saying:
“We reviewed all available safety data following yesterday’s incident, based on the initial information, we concluded that the inspection interval should be stepped up for the hollow fan blades that are unique to this model of engine, used solely on Boeing 777 airplanes.”
So far, investigations into why the engine burst into flame are only speculative, but they believe that a fan blade broke off and got sucked into the engine, causing a chain reaction that eventually resulted in the engine failure.
