The head of the Federal Aviation Administration said Sunday that they needed “immediate or phase-up inspection” of all Boeing 777 aircraft equipped with a special Pratt & Whitney engine model in one day, as the jet suffered a dramatic engine failure in Colorado had to face.
In addition, on Sunday, United Airlines, the only US carrier affected by the FAA order, said it was currently using 24 Boeing 777 aircraft in its fleet with Pratt & Whitney engines.
The FAA’s announcement came shortly after the order of its counterpart in Japan, preventing the aircraft from flying, affecting 32 jets operated by All Nippon Airways and Japan Airways. Both Japanese and American orders apply only to Boeing 777s equipped with Pratt & Whitney PW4000 engines.
“We reviewed all available security data after yesterday’s incident,” FAA Administrator, Steve Dixon said in a statement. “Based on preliminary information, we concluded that the inspection interval should be elevated for hollow fan blades that are unique to this model of engine, used only on Boeing 777 airplanes.”
There were no injuries in the episode on Saturday involving United Airlines Flight 328 in Colorado, but the plane dropped debris in three neighborhoods before landing safely in Denver.
In a statement on Sunday, United said “Safety remains our top priority for our employees and our customers.” It continued, “That’s why our pilots and flight attendants participate in extensive training to prepare and manage events such as United Flight 328. And we are proud of our professionalism and our day-to-day work Surrender to safety and when it happens like an emergency. “
Mr Dixon said the FAA was working with its counterparts worldwide and said its security experts were meeting “in the evening” with Pratt & Whitney and Boeing to complete the details of the necessary inspections. Only the United States, Japan and South Korea operate Boeing 777s with affected Pratt & Whitney PW4000 engine models, according to the agency.
A spokesperson for Japan Airways said the airline had already stopped using 13 Boeing 777s in its fleet which are equipped with engines before issuing instructions by the aviation authority. Only three scheduled flights were affected. The airline said last year that it planned to remove all 13 aircraft from its fleet early next year.
