Проблема с токсичным дымом в салоне у семейства А320 оказывается более чем серьезная. Ее просто заметали под ковер на протяжении 20ти лет

Delta Air Lines is replacing power units on more than 300 of its Airbus jets in an effort to stem cases in which toxic fumes have leaked into the air supply and led to health and safety risks for passengers and crew.

The move is one of the most aggressive efforts by a major U.S. airline to address what in recent years has increasingly become a hidden hazard of modern air travel.

The airline is about 90% of its way through the process of upgrading the engines, a type known as the auxiliary power unit, on each of its Airbus A320 family jets, according to a spokesman for Delta. The airline operates 310 of the narrow-body type, including 76 of the latest generation models as of the end of June.

The APU is typically a third engine that sits in the tail of an aircraft and is used to generate electricity and pump air into the cockpit and cabin when the two primary engines aren’t running, and for example often during taxiing. A leak in the APU can also contaminate the air even when it isn’t in use, according to maintenance specialists and internal troubleshooting documents.

Airbus has previously identified the APU and how it is integrated on the A320 as a leading cause of toxic fumes contaminating the so-called bleed air system. A fume event typically occurs when oil leaks into the engine or power unit’s compression chamber and is vaporized at extreme heats, releasing unknown quantities of neurotoxins and other chemicals into the cockpit and cabin air.

The Wall Street Journal reported earlier this month that fume events have been surging in recent years, driven in large part by incidents on the Airbus A320 family, and that they have led to brain injuries and other illnesses in both crew and passengers.

Delta hasn’t previously disclosed the APU replacement program, which began in 2022.

Replacing the APU, which can become more prone to fume events with age, mitigates some of the risks from toxic leaks but doesn’t address them entirely. Airbus last year found that most cases on the A320 were linked to leaks entering the APU via an air inlet on the aircraft’s belly.

Another separate cause is leaks in the jet engines themselves, which provide most of the bleed-air supply when active.

Delta and other U.S. carriers have seen a surge of incidents across A320 family aircraft that has outpaced the number of reported fume events on other Airbus and Boeing aircraft, according to the Journal’s analysis of reports to the Federal Aviation Administration.

Over the past year, APU-related fumes on Delta’s A320 jets have led to emergency diversions and abandoned takeoffs, pilots donning oxygen masks and an instance of a passenger vomiting, the analysis showed.

It is difficult to assess whether some carriers have more of those incidents than others because not all fume events are flagged by crew, and airlines have different standards when reporting to the FAA.

A Delta spokesman said that though fume events are rare, the company treats each seriously, as it does for all safety matters. “Nothing is more important than the safety of our customers and people,” he said.

An Airbus spokeswoman referred to a previous statement that the company was working with airlines and regulators to enhance its aircraft and ensure “the best possible cabin environment for passengers and crew.” That statement also said: “Airbus aircraft are designed and manufactured according to all relevant and applicable airworthiness requirements.”

Delta declined to comment on costs associated with the replacement program or to identify the manufacturers of APUs on its A320 fleet, but records filed to the FAA show that Delta operates models made by Honeywell and RTX’s Pratt & Whitney.

Both Honeywell, which dominates the APU market, and Pratt & Whitney have had issues with models deployed on the A320 family for years, according to internal maintenance and company documents, engineering specialists and legal complaints. The issues have spanned defects with gearboxes and cooling fans, but predominantly affected seals meant to protect against oil lubricants leaking into the air supply.

Pratt & Whitney introduced three separate fixes in 2019 and 2020 for its APU model on the A320 family, according to an internal Airbus presentation, while Honeywell has developed new upgrades to address defects including for the APU’s load compressor seal.


The Honeywell fix—the company’s third attempt to address problems with that seal since 2007—was announced late last year. In a marketing document at the time, the company listed as a primary benefit of the upgrade: “An improved passenger experience thanks to reduced possibility of odor in cabin events.”

American Airlines has separately been upgrading its Honeywell APU load compressor seals across its A320 fleet since April 2023, a spokeswoman said.

A similar version of Honeywell’s APU is also used on Boeing’s 737 family of jets.

Honeywell and Pratt & Whitney declined to comment.

The increase in incidents follows changes to maintenance requirements that Airbus began approving from 2017, which allowed airlines to regularly send aircraft back into service after a fume event had occurred.

Two years after the change, Airbus and Honeywell issued a “good practices guide” to help airlines mitigate APU-driven fume events. That included extensive weekly visual inspections to the power unit and a suggestion that pilots wait three minutes after turning on the APU before activating the bleed air to give the APU seals time to adjust to the temperatures and start working properly.


The companies also suggested that airlines consider operating flights with the APU air supply turned off—removing air conditioning on the ground—if conducting maintenance might cause disruption to their flight schedules.

“Corrective maintenance action can be planned at a better opportunity,” Airbus and Honeywell wrote in the March 2019 joint presentation. They also reminded airlines that the precautions for mitigating fume events were only an optional guide to help operators suffering from repetitive fume events.

Internal maintenance and other documents show that Airbus and Honeywell have been aware of fumes-related issues with load compressor seals in the APU for over two decades.

An internal Airbus email from 2019 showed staffers debating how best to address a request from American Airlines, which had asked for specific data on root causes of fume events. The Airbus team found an internal study conducted over 20 years ago that identified issues with that specific seal.


“Don’t officially give them the report because it identifies the airline and aircraft etc, and mentions APU load compressor seal oil leakage (back in 2003 !!),” the Airbus staffer wrote, according to the email exchange reviewed by the Journal.

An airline internal maintenance document shows that Airbus was aware of the issue even sooner. The plane maker notified customers in November 2001 that one operator had experienced “significant oil fumes in the cabin” during a flight due to a worn load compressor seal in the Honeywell APU.

A lawsuit filed Sep. 3 on behalf of three former JetBlue flight attendants against the airline, Airbus and Honeywell cites incidents between 2022 and last year in which oil had leaked from Honeywell APUs and caused noxious fumes to enter the cabin. The suit alleges that the exposure led to lasting symptoms including heart palpitations, tremors and physical and cognitive impairment.


In one example from September 2022, fumes led to passengers complaining of nausea, a child suffering a nosebleed and four JetBlue flight attendants in the hospital. The suit alleges the same aircraft had been diverted two days earlier due to a passenger who was struggling to breathe.

The three companies that are defendants haven’t yet replied to the lawsuit.

In a presentation to airlines last year, Airbus acknowledged that upgrades to seals and other faulty components within the APU would solve only a portion of reported fume events.

Airbus, as part of an internal program called Project Fresh, reviewed instances of fumes from 2016 to 2021 and found 12% related to oil leaks internal to the APU. The remainder were caused by the APU ingesting oil through its air inlet at the bottom of the aircraft. That includes leaks from overfilling of oil reservoirs, landing gear hydraulic fluid or de-icing liquids.


Airbus outlined three fixes, including the most radical, a design change that moved the position of the inlet to the top of the aircraft, and which Airbus said would reduce “smell” events by 85%.

That fix will only apply to new aircraft. For older aircraft, Airbus proposed other changes that it said are less effective.

Franco-Italian aircraft manufacturer ATR recently completed market studies it says leave no doubt its turboprops are best suited to fill what it views as substantial demand for new regional aircraft in the USA.

The company last week highlighted those studies to several US regional airline chief executives in Washington, DC, while citing new cabin configurations it describes as tailored to the higher-spending travellers US airlines are so keen to court.

ATR says its turboprops are ideal replacements for hundreds of 50-seat jets nearing retirement. (They are also, at least as of now, the only new-production replacements in that size category.)

ATR’s new cabin configurations include its “HighLine” concept for a 50-seat ATR 72-600. While that type traditionally carries about 70 passengers, the HighLine concept has 10 first-class, 20 premium-economy and 20 baseline-economy seats.

“With these configurations we can… capture the premium demand and improve the profitability of the airlines when compared to the CRJ200s or the Embraer 145,” ATR head of business development Takek Ben Omrane said on 17 September. “We are working with airlines to fine tune those layouts.”

Perhaps most notably, ATR proposes adding a forward boarding door to its 72-600. ATRs have long only had rear boarding doors, a sticking point for US airlines that bristle at disrupting the traditional premium-first boarding process.

ATR has already completed engineering work related to the forward door and is eager for a US customer to place orders.

“If you’re boarding from the rear of the aircraft, it kind of disrupts the flow that you are used to,” says ATR head of Americas Christopher Jones. “If there was a US launch customer, with a suitable scale, we would go forward with that development.”

“The product is defined… The next step is to have the right market conditions and a proper large customer base to effectively industrialise it,” adds ATR senior vice-president of commercial Alexis Vidal.

Though ATR rolled out the HighLine concepts several years ago, it has since completed a thorough US market evaluation.

US regional airlines operate some 300 50-seat regional jets, including about 200 ERJ140s and ERJ145s and 90 MHI RJ Aviation CRJ200s, according to fleet data provider Cirium.

That figure is down from about 800 50-seaters ten years ago. During that period, US airlines also divested essentially all their turboprops, replacing the smaller aircraft with larger regional jets such as CRJ700s, CRJ900s and E175s.

ATR says airlines will retire most of the 300 small jets by 2035.

If carriers fail to replace them with new 50-seaters, they will likely have no choice but to cut flights to small US communities – places lacking enough demand to fill larger jets, ATR says. It estimates some 30 US cities could lose all air service as a result, citing a study conducted in partnership with Georgia Institute of Technology.

Such would continue a multi-decade trend.

Many regional US air links disappeared in recent decades as the country’s regional airlines consolidated and acquired massive fleets of 75-seat regional jets.

“Demand is now requiring everybody to go through larger hubs,” says Rick Hoefling, chief executive of US regional carrier CommuteAir. “If you’re in these smaller cities, you don’t have direct service anymore.”

GoJet Airlines CEO Rick Leach notes that commuter airlines once operated 20 flights daily from St Louis to places like Springfield, Illinois and Colombia, Missouri. Those flights no longer exists; flying to those cities now means traversing a major hub.

Indeed, 540 US airports had scheduled air service in January, down 7.2% from 582 airports in 2009, even as airlines operated more flights, and with larger aircraft, according to data from the Regional Airline Association. Smaller cities suffered the most lost flights.

ATR is the only Western manufacturer still producing passenger aircraft in the small regional aircraft category, offering its 30-50-seat 42-600 and 44-78-seat 42-700, both powered by Pratt & Whitney Canada PW127XTs.

“We’ve been a survivor and an innovator at the same time,” says ATR’s Jones.

Embraer and Bombardier halted production of their small jets years ago. ATR alone has owned the segment since De Havilland Canada in 2022 stopped assembling Dash 8-400s, though De Havilland has left open the possibility of rebooting production.


“We remain engaged in pre-launch activities with both customers and suppliers and are on track to make a production decision in 2026 for both a 50- and 80-seat aircraft,” the Canadian manufacturer tells FlightGlobal.

Embraer had in recent years teased at developing a new turboprop, but the idea languished due to engine manufacturers not offering clean-sheet powerplants capable of substantially better efficiency. “Nothing has changed in that regard,” says Embraer chief commercial officer Martyn Holmes.

Start-ups like Maeve Aerospace and Heart Aerospace are working to develop hybrid-electric regional aircraft, but such programmes are unsure of success and years from fruition.

The lack of options has US airline chiefs frustrated.

“We want to encourage more product development, more manufacturing, more opportunities,” says Timothy Wang, CEO of Endeavor Air, a CRJ700 and CRJ900 operator owned by Delta Air Lines. “We’re going to have to do something in the future.”

ATR says its turboprops are the solution. It says the types cost 30% less per seat to operate than 50-seat jets, while having comparable cabin noise.

Best of all, they are available now.

The company also plans before 2030 to fly a hybrid-electric-modified 72-600 demonstrator, part of a European Union Clean Aviation initiative. ATR and its partners – which include Safran and RTX subsidiaries Pratt & Whitney Canada and Collins Aerospace – will replace the aircraft’s right PW127XT with a 2MW hybrid-system, they say.

“We keep the thermal engine and we add an electric motor on the gearbox to use this extra power [and] optimise for every part of the flight,” ATR senior vice-president of engineering Daniel Cuchet said last week.

“With these new technologies, we’re introducing this high voltage directly into the engine,” adds RTX chief engineer Michael Winter. “We’re learning a lot and we’re working through [it] with… certification authorities.”

ATR hopes in the mid-2030s to bring to market a hybrid variant that is 30% more efficient than today’s aircraft, with 20% efficiency gained from the powerplant and 10% from aircraft-level changes.

Airline CEOs see promise in ATR’s updates, specifically its forward boarding door and 50-seat layout.

“I think that ATR is on the right track in terms of looking at matching or exceeding the cabin experience, the comfort” of regional jets, says Endeavor chief Wang.

Delta clarifies it has no plans to acquire ATRs.

The CEOs also suspect that US flyers, now long accustomed to jets, will need some convincing before embracing turboprops.

“We’ve got to get them [to understand] the fact that the technology on this aircraft is more advanced than the big jets you are flying in many cases, or the regional jets… It is not old technology,” says GoJet’s Leach.

“You’ve got to get out there and market it to the masses” Leach advises ATR.

Most airlines have spent the 2020s navigating day-to-day operational challenges. Ramping up capacity again to meet a surge in demand after the COVID-19 pandemic proved to be difficult and frustrating. Those headwinds were compounded by commercial aviation’s supply chain and production crisis alongside engine durability and quality issues that have grounded a substantial number of aircraft.

But more than two decades after Boeing launched development of its last clean-sheet aircraft, a new survey of airlines, lessors, manufacturers, component suppliers and maintenance, repair and overhaul providers reveals a high degree of interest in a next-generation narrowbody that Embraer has been studying for some time. Results of the global survey, conducted by Aviation Week Network in partnership with analysts at Bank of America, show that a large share of operators are eager for both next-generation passenger jets and more competition in the commercial aircraft market. They are also willing to consider unusual designs. Airlines accounted for 45% of the 492 survey respondents.

“The survey respondents are supportive of Embraer doing this by themselves, even more solo than with Boeing,” says Ron Epstein, Bank of America global research aerospace and defense analyst. “There is real appetite for a third legitimate manufacturer.”

1759352630105.png

Having dominated the commercial aircraft market as a duopoly since 1987, Airbus and Boeing face little competitive pressure to develop cutting-edge successors to the A320neo and 737 MAX families. Both companies say they do not anticipate a new narrowbody entering service before the mid-2030s, and recent comments indicate that their timing continues to slide to the right.

Airbus Group CEO Guillaume Faury wants to see production stability at high rates and better margins in the airframer’s commercial aircraft business and for its suppliers for several years before a launch decision. And Boeing CEO Kelly Ortberg says that while his company eventually will build a new commercial aircraft, the timing is not right to start now. Boeing has only just begun the long process of rebuilding from its self-inflicted production and quality crisis. Technology evolution timelines have put the two incumbent players on similar terrain. Both also have substantial backlogs that an earlier launch of a successor product would threaten.

Industry veterans say the go-slow approach by Airbus and Boeing, which runs counter to the pressing need for airlines to reduce emissions, may have opened the door a crack for a third player to disrupt the duopoly.

“The path forward for a killer product isn’t mysterious: It’s a better A321XLR with a better wing, better engine power and newer features,” AeroDynamic Advisory Managing Director Richard Aboulafia says. “The A321 is still based on an almost 40-year-old platform.”

“Airlines want something that is like an A320neo in terms of range and size,” Epstein says. “It does not have to be radically new. They don’t have to reinvent the wheel.”

Boeing’s previous CEO, David Calhoun, predicted that disrupter would be Comac, which introduced its C919 into the Chinese domestic market in 2023. But the C919 is based on present-day technology, and skeptics note that Comac faces the hurdles of achieving certification by international airworthiness authorities and setting up a far-flung maintenance network if it truly wants to be a global competitor.

Embraer has looked at upsizing into the narrowbody market before, but it concluded that taking on the duopoly would be too risky. After a scuttled merger with Boeing, the Brazilian airframer is giving the idea a second look as it considers future investments. Embraer has quietly continued studies of various aircraft concepts and had signaled that it could announce a decision on its next development in 2025. But CEO Francisco Gomes Neto appeared to pull back on that at the end of 2024, signaling that a launch decision might not come until after 2030.

“They are not ready,” Aboulafia says. “This has to be some grand alliance of suppliers, financiers and even countries. It could be that Gomes Neto’s job is to come up with an idea and attract investors and partners. If they show up, then Embraer builds it.”

Yet customers appear to be eager to order sooner rather than later. An overwhelming 85% of airline respondents and 78% of total respondents agreed or strongly agreed that a new aircraft for service entry between 2029 and 2032 equipped with the latest generation of current-technology engines—such as an evolution of the Pratt & Whitney geared turbofan, the CFM International Leap or Rolls-Royce’s UltraFan project—would be “compelling to purchase.”

1759352903106.png



A commanding 71% of all respondents agreed or strongly agreed that if Airbus, Boeing and Embraer all launched a new aircraft for service entry at roughly the same time, they would still go for the Embraer offering if they were convinced of its merits; only 5% of airlines and 6% overall disagreed. More generally, 81% of the airline respondents said they would be “very supportive” of a third commercial aircraft manufacturer.

According to industry sources, a group of large airlines has hinted to Embraer that they would place sizable orders for a new aircraft, should it be launched.

“Given where Boeing is now and where travel markets are going, it does seem to be now or never for Embraer,” Epstein says. “The sentiment could change in five years.” He believes there is a “50-50 chance” that Embraer will launch a larger commercial aircraft in the coming years. Epstein believes that service entry could occur in the early 2030s, as airline preferences in the survey show. On the other hand, Embraer has demonstrated its cautiousness throughout its history and could opt for a less risky path, which could be a new executive jet.

In commercial aviation, there are also unconventional disrupters. Backed by a $235 million U.S. Air Force development contract, California startup JetZero is working on a blended wing body aircraft that could be used as both a military tanker and a civil airliner. The company is hoping the aircraft, powered by conventional engines, could enter service in the middle of the next decade.

The survey results indicate a clear preference for a more economical, longer-range, next-generation aircraft that can replace the 737-8 and A320neo. The two aircraft have been the baseline versions of the Boeing and Airbus narrowbody families, yet the larger A321neo has become the best-selling type by far in recent years, and Boeing has seen some improved sales success for the 737-10, even though the type has not achieved certification.

1759353029924.png


So what do airlines want in a new aircraft? The most votes (47%) were for an aircraft in the 150-179-seat category, while 26% of respondents preferred a larger capacity of 180-199 seats. Only 9% of airline respondents favored a cabin with 230 or more seats. In a notable contrast, the smaller number of lessor respondents expressed preference for a slightly larger cabin; 43% chose 180-199 seats and 29% 200-229 seats.

Respondents also showed a preference for longer range, with 52% of airlines voting for a narrowbody that could fly up to 4,000 nm, exceeding the baseline versions of the 737 MAX and the A320neo considerably. Only 25% said 3,500 nm would be sufficient, while 23% would prefer up to 5,000 nm—beyond the range of the A321XLR.

Turning to the fuselage, 41% of airline respondents and 43% of lessors expressed a desire for a traditional narrowbody design, while 28% of airlines favor a small widebody, an architecture most recently studied for Boeing’s proposed and then shelved New Midmarket Airplane (NMA) concept. “Maybe Boeing’s NMA wasn’t a terrible idea,” Aboulafia says.

1759353098165.png


Notably, 12% of airlines see a blended wing body as the most promising option, but only 2% favor the truss-braced wing option pursued by Boeing in the X-66A project.

Thirty-two percent of airline respondents said a 15% overall improvement in operating costs would be sufficient in a new aircraft, but 44% want a 20% gain. Two-thirds of respondents are seeking a 15-20% fuel burn reduction over the existing generation of aircraft, while 17% want a gain of 25% or more. That is a significant statement by customers, as manufacturers have been warning that technology will not be ready to meet expectations for some time.

Potential buyers also largely share the view that the commercial aircraft supply chain could support a third manufacturer—more than two-thirds agreed or strongly agreed, while only 9% disagreed or strongly disagreed.
