United Airlines grounded 25 of its Boeing 777-200 aircraft after failing to inspect their wings

United Airlines revealed Wednesday it grounded about 25 of its Boeing 777-200 planes – just days before one of them was forced to turn back only minutes after taking off.

United grounded dozens of the planes after realizing that some of its aircraft had not undergone required inspections of the front edges of the wings, or the wing slats.

It led to the airline canceling flights on Monday night and Tuesday morning. Those passengers affected were rebooked.

But on Wednesday night, a 777-200 aircraft that had been cleared to fly was forced to turn back after taking off from Newark Airport in New Jersey following an issue with its hydraulic system. The wing slats are part of the hydraulic system. 

The FAA has launched an investigation into the incident but United has not commented if the issue is at all connected to the grounding of similar aircraft. 

The Federal Aviation Administration explained how United grounded 25 of the jets after discovering it had failed to inspect slats on the wing edges that are used during takeoffs and landings.

The FAA said United reported the issue, and the FAA is reviewing circumstances that led to the missed inspections.

United said earlier this week afternoon that it had inspected 10 of the planes and was working with the FAA to return the others to flying in the next two weeks without causing additional flight cancellations.

‘We’ve completed inspections on 10 of those aircraft, and are working with the FAA to return others to service while inspections are ongoing over the next two weeks,’ United said in a statement.

The FAA said it was reviewing United’s inspection plan ‘as well as looking into the circumstances that led to the missed inspections.’

In May, the FAA cleared United’s 52 Boeing 777 planes equipped with Pratt & Whitney (PW) 4000 engines to return to service. 

The jets were grounded after the failure of a Pratt & Whitney engine on one that caused parts of the housing to fall on the Denver area.

The United flight to Honolulu suffered engine failure and showered debris over nearby cities and made an emergency landing in February 2021.   

A loud bang was heard just four minutes after take off and pieces of the engine began to plummet to the ground over Broomfield, Colorado.

Jet engine parts were scattered around the entire suburb, with the entire engine inlet lip ending up in one piece in a resident’s front yard.

No one was injured and the plane safely returned to the airport. 

United said that he wing leading-edge panel inspections of some of those 777-200s are not related to engines or recent engine work. 

They said the inspections in most cases can be completed overnight. 

United’s Boeing 777s are some of the oldest models of their kind in the world. 

The 777 planes seat between 276 and 364 passengers, according to United’s website, and are mostly used on long international flights.

Meanwhile, the FAA has launched an investigation after a United plane was forced to make an emergency landing when a shower of sparks flew off and debris fell to the ground moments after taking off from Newark Airport in New Jersey.

The Boeing 777-200ER, which took off from Newark heading for Sao Paulo, Brazil, at 11.24pm on Wednesday night had to enter a holding pattern at 24,000 feet over the Atlantic Ocean after experiencing what is suspected to be a hydraulic pressure pump failure on landing the landing gear. 

Approximately an hour and a half later, after dumping fuel over the ocean to reduce weight, the aircraft made a safe emergency landing back at Newark Airport. 

The FAA have now confirmed they are probing the cause of the malfunction. 

The terrifying moment was purportedly caught on video by a nearby plane spotter, who captured the shower of sparks streaming from close to the landing gear compartment of the Boeing 777.

He also took a photograph of a piece of rectangular, rusty-looking piece of debris that fell to the ground.

Despite the dramatic scenes, the plane landed safely after the crew reported an emergency and that an investigation is under way.

There were no reports of any casualties or injuries among the crew and passengers.

In a statement, United Airlines said: ‘After our aircraft experienced a mechanical issue shortly after takeoff, it remained in the air to burn fuel and then landed safely. 

‘Passengers deplaned at the gate and a new aircraft is scheduled to depart this morning.’ 

The FFA said: ‘United Airlines Flight 149, a Boeing 777-200, landed safely at Newark Liberty International Airport shortly before 1am local time today after the crew reported an emergency. 

‘The flight departed Newark and was headed to São Paulo, Brazil before it returned. The FAA will investigate.’ 

Boeing 777s are equipped with three hydraulic systems. The left, center and right systems deliver hydraulic fluid at a rated pressure to operate flight controls, flap systems, actuators, landing gear and brakes. 

Primary hydraulic power for the left and right systems is provided by two engine-driven pumps and supplemented by two on-demand electric motor-driven pumps, according to power company Eaton.

On Thursday, US securities officials fined Boeing $200 million over the aviation giant’s misleading assurances about the safety of the 737 MAX airplane following two deadly crashes, regulators announced Thursday.

Boeing agreed to the penalty to settle charges it ‘negligently violated the antifraud provisions’ of US securities laws, the Securities and Exchange Commission said in a statement, saying the company and its leader ‘put profits over people.’

Boeing’s former chief executive, Dennis Muilenburg, also agreed to pay $1 million to settle the same charges in the civil case.

Boeing Max 737’s two deadly crashes: What happened?

Boeing was forced to ground the 737 Max after the crashes in Indonesia and Ethiopia happened less than six months apart.

The first disaster happened October 29, 2018, when a Max flying as Lion Air flight JT 610 fell into the Java Sea 15 minutes after taking off from Jakarta.

All 189 aboard the plane died, including 180 Indonesians, one Italian and one Indian.

The second crash occurred on March 10, 2019, when Ethiopian Airlines Flight ET 302, which also was a Max jet, took off from Bole International Airport in the Ethiopian capital and crashed. 

All 157 people onboard the plane died. 

US carriers American, United and Southwest had to cancel flights for the holidays, including over Christmas and into the new year, after the plane was grounded around the world.  

Boeing reported on July 14, 2019, that customers canceled orders for 60 of the grounded 737 MAX jets in June. 

The aircraft maker removed another 123 planes from its backlog over doubts that the deals will be completed.

The settlement marks the latest hit to Boeing over the MAX following the Lion Air Crash in Indonesia in October 2018 and the Ethiopian Airlines crash in Ethiopia in March 2019, which together claimed nearly 350 lives.

One month after the first crash, a Boeing press release approved by Muilenburg ‘selectively highlighted certain facts,’ implying pilot error and poor aircraft maintenance contributed to the crash.

The press release also attested to the aircraft’s safety, not disclosing that Boeing knew a key flight handling system, the Maneuvering Characteristics Augmentation System (MCAS), posed safety issues and was being redesigned.

After the second crash, Boeing and Muilenburg assured the public that there was ‘no surprise or gap’ in the federal certification of the MAX despite being aware of contrary information, the SEC said.

‘In times of crisis and tragedy, it is especially important that public companies and executives provide full, fair, and truthful disclosures to the markets,’ said SEC Chair Gary Gensler in a press release.

‘The Boeing Company and its former CEO, Dennis Muilenburg, failed in this most basic obligation. They misled investors by providing assurances about the safety of the 737 MAX, despite knowing about serious safety concerns.’

The SEC said both Boeing and Muilenburg, in agreeing to pay the penalties, did not admit or deny the agency’s findings.

Boeing said the agreement ‘fully resolves’ the SEC’s inquiry and is part of the company’s ‘broader effort to responsibly resolve outstanding legal matters related to the 737 MAX accidents in a manner that serves the best interests of our shareholders, employees, and other stakeholders,’ a company spokesman said.

The coronavirus pandemic has compounded the crisis over the grounding of Boeing’s 737 MAX following two fatal crashes that killed 346 people. Pictured, wreckage is piled at the crash scene of Ethiopian Airlines flight ET302 near Bishoftu, Ethiopia

The crash of the Nairobi-bound Boeing 737 MAX six minutes after takeoff on March 10, 2019, killed all 157 people on board. Pictured, wreckage is piled at the crash scene of Ethiopian Airlines flight ET302 near Bishoftu, Ethiopia

‘We will never forget those lost on Lion Air Flight 610 and Ethiopian Airlines Flight 302, and we have made broad and deep changes across our company in response to those accidents.’

US air safety authorities cleared Boeing’s 737 MAX to resume service in November 2020 following a 20-month grounding after the crashes.

A principal cause of the two crashes was identified as the MCAS, which was supposed to keep the plane from stalling as it ascended but instead forced the nose of the plane downward. The Federal Aviation Administration required Boeing to upgrade this system to address the flaw.

In January 2021, Boeing agreed to pay $2.5 billion to settle a US criminal charge over claims the company defrauded regulators overseeing the 737 MAX.
