In response to the incident, Japan has asked all airlines using Boeing 777s with the same Pratt & Whitney 4000 engine to avoid its airspace.

Boeing said it supported Japan's decision and has recommended suspending operations of all 777s with the same engine while an investigation into the incident continues. The manufacturer says there are 69 Boeing 777s currently in service worldwide with this engine.

According to the Federal Aviation Administration (FAA), United is the only US airline flying such planes, with the others being in Japan and South Korea.

"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."

The FAA is meeting representatives from the engine firm and Boeing.

The National Transportation Safety Board's initial finding is that most of the damage occurred in the right engine, where two fan blades were fractured and other blades also impacted. The main body of the aeroplane suffered only minor damage.

In 2018, the right engine of a United Airlines plane broke shortly before it landed in Honolulu. Following an investigation, the National Transportation Safety Board said the incident was caused by a full-length fan blade fracture.

As the aircraft is 26 years old, none of them.
Down to the airline.

• Boeing?: Engine cowling design, integration design, engine design oversight, and they have overall responsibility that must not be shirked or 'contracted out';
  
  
• Raytheon?: Engine design if it is their design;
  
  
• FAA?: Oversight and design and safety requirements and safety tests sign-off.
  

Or... At least that is how it should be...?

Fly safe folks!

(Reuters) - United Airlines Holdings Inc has ordered 25 new Boeing 737 MAX aircraft to receive in 2023 and moved up the delivery of others as it prepares to replace aging jets and meet expected post-pandemic growth in demand, the company said on Monday.

Relatives of some of the passengers who died in the crash of an Ethiopian Airlines marked Wednesday's two-year anniversary of the disaster by seeking the improbable: a reversal of government orders that let Boeing 737 Max jets fly again.

They are also seeking the removal of several top officials at the Federal Aviation Administration, which certified the plane and let it keep flying after another Max crashed in Indonesia, five months before the Ethiopian accident. A total of 346 people died in both crashes. The family members say they are trying to prevent a third crash...

The fund is part of a $2.5 billion Justice Department settlement reached in January with Boeing Co. after prosecutors charged the company with fraud over the certification of the 737 MAX following a Lion Air crash on Oct. 29, 2019 and an Ethiopian Airlines disaster on March 10, 2019...

... The DOJ settlement includes a fine of $243.6 million and compensation to airlines of $1.77 billion over fraud conspiracy charges related to the plane’s flawed design.

Chris Moore, who lost his daughter in the Ethiopian crash, noted that the fine is only 10% of the total settlement, or the cost of about two 737 MAX planes.

“If this isn’t a slap in the face for us – I don’t know what is. It definitely is only a slap on their wrist,” he said.

The Justice Department said in January, “Boeing’s employees chose the path of profit over candor by concealing material information from the FAA concerning the operation of its 737 Max airplane and engaging in an effort to cover up their deception.”...

... “I have been and remain seriously concerned that Boeing was able to put a fatally flawed aircraft into service under FAA’s certification process — a fundamental indictment of the shortcomings of that process,” he said.

Sen. Richard Blumenthal, D-Conn., said the report indicated concealment by Boeing and negligence by the FAA.

The same inspector general’s office reported last year that Boeing failed to disclose to the FAA changes it made to MCAS. In January, Boeing agreed to a $2.5 billion settlement with the Justice Department to avoid prosecution for defrauding the FAA...

Boeing Co. grounded dozens of 737 Max jets to repair an electrical flaw that emerged in recently delivered models, forcing airlines to cancel flights and line up replacement aircraft.

U.S. carriers including Southwest Airlines Co., American Airlines Group Inc. and United Airlines Holdings Inc. parked a combined 67 of the workhorse planes Friday, about a third of the Max jets in service worldwide. The manufacturing glitch affects a subset of aircraft at 16 airlines, not the entire Max fleet, Boeing said in a statement

Technology in many respects has made our lives easier.
Unfortunately, it will always have a major flaw - human error.
