ACJ TwoTwenty FAA approval: the headline is regulatory. The story is commercial. On April 6, 2026, Comlux America secured a Supplemental Type Certificate (STC) from the Federal Aviation Administration (FAA) for the ACJ TwoTwenty cabin. Not the aircraft. Just the cabin — and that distinction is where most of the trade coverage goes soft. What this certificate actually does is open the FAA’s N-number register to a programme that already has four delivered aircraft, a fifth in completion, and a 28-aircraft backlog growing inside Comlux’s Indianapolis facility. The paperwork is narrow. The timing is not.
Comlux secured the approval with DOA21, the group’s Malta-based design office and an Union Aviation Safety Agency (EASA)-approved Design Organisation holding Part-21 Subpart J authority. It also gives the cabin both FAA and EASA approval. As Adam White, CEO, Comlux America put it: “While no ACJ TwoTwenty to date is on the N register, today marks the biggest step forward in ensuring when this comes, it will be a timely, straightforward process.”
Peter Gaughan framed the regulatory significance from the design-office side. “This marks yet another significant milestone for the DOA and the whole Comlux team and another first for the ACJ TwoTwenty type.” — Peter Gaughan, CEO, DOA21.
What the FAA approved
This was not a new type certificate for the whole aircraft. It was approval for the cabin interior and the design changes associated with it. That distinction matters. The Airbus Corporate Jets (ACJ) TwoTwenty is based on the Airbus A220-100, formerly the Bombardier CSeries CS100. The April 2026 milestone concerns the completed Comlux cabin that goes inside that airframe.
Comlux’s release says the STC allows DOA21 to certify design modifications of ACJ TwoTwenty cabins to FAA standards. In practical terms, that gives North American clients a clearer path for cabin acceptance, project execution, and eventual U.S. registration. It also tightens the wording around the story itself: this is FAA approval for the cabin, not a fresh certification event for the entire aircraft.
AIN’s April 7, 2026 report reflected that distinction. It treated the development as U.S. approval for the ACJ TwoTwenty cabin. It also noted that the move followed Comlux’s earlier FAA work on the first Boeing Business Jet (BBJ) MAX 8 cabin. That is a more useful way to frame the news than describing it as if the entire aircraft had suddenly been certified in the United States.
Why the approval matters now
The timing matters because the programme is no longer theoretical. As of April 2026, and as AeroTime’s April 9, 2026 report confirmed from Comlux sources, four ACJ TwoTwenty aircraft had been delivered, another four sat in the completion pipeline, the cabin design already held EASA certification, and Comlux’s broader Indianapolis facility carried a 28-aircraft backlog.
The approval also matters because jurisdiction shapes the deal as much as the cabin itself. A product that already has both EASA and FAA acceptance is easier to sell in North America than one that still has to cross a regulatory gap. That is the commercial point behind White’s N-register remark, and it is the simplest reason this announcement deserves attention.
Airbus has long pitched the ACJ TwoTwenty as a middle ground: more cabin space than conventional ultra-long-range business jets, but less size and complexity than a full narrowbody airliner conversion. In its October 6, 2020 launch material, Airbus pitched the aircraft as offering three times more cabin space than competing business jets while cutting operating costs by roughly a third, thanks to the A220 platform underneath. The new STC supports that argument because it removes one of the practical objections a U.S. buyer could raise. It does not close the sale on its own, but it makes the conversation easier.
The approval also fits Comlux’s broader U.S. completion push in Indianapolis. Readers who want the airline-facing side of that work can see our Fliegerfaust analysis of Comlux’s A220-300 completion work for Magnifica Air. That programme is separate from the ACJ TwoTwenty, but it shows how Comlux is extending its A220 cabin expertise beyond the corporate-jet niche.
Fifth cabin arrives as the line settles into rhythm
Inside that broader push, the ACJ TwoTwenty line itself kept moving. By the spring of 2025, the programme looked less like a showcase and more like a scheduled line. In its May 26, 2025 fifth-aircraft update, Comlux said the fifth green ACJ TwoTwenty had arrived in Indianapolis from Airbus Canada in Montréal and would enter a 10-month cabin completion. The company added that the next two airframes were scheduled to arrive in November and December 2025, with five aircraft bays already at work inside the Comlux Completion hangar.
The scaling went beyond the ACJ TwoTwenty alone. In its October 15, 2025 record-backlog announcement, Comlux America said its order book had reached 28 aircraft, spanning six A220s for Magnifica Air, four ACJ TwoTwentys, fifteen A321neos, and three A320neos. To absorb that pipeline, the company said it would add two new hangars by the first quarter of 2026, creating four additional narrowbody bays, with a further four bays slated for the end of 2026. Comlux America also said its workforce had grown 20 percent in 2025, with another 20 percent planned for 2026.
U.S. demand signals line up with the timing
The timing also fits a broader demand signal that Airbus itself had flagged months earlier. In its October 13, 2025 study of U.S. corporations, Airbus Corporate Jets reported that:
- 96 percent of surveyed U.S. corporations that own or lease business aircraft expected to upgrade to newer or better models within five years
- 41 percent cited the need for larger aircraft as more executives were using them
- 25 percent pointed to the need for greater range
- 67 percent cited new U.S. tax legislation allowing businesses to write off the full purchase price of a corporate jet used for business travel
The survey was commissioned by Airbus and conducted by independent research firm Pureprofile in September 2025, covering 100 senior executives at U.S. corporations with annual revenue above $500 million. That is manufacturer-commissioned research, not a neutral industry census. Even so, it signals where Airbus sees the market heading — and it helps explain why a U.S. cabin approval matters now rather than later.
Family offices echo the same upgrade signal
A parallel Airbus study pointed the same way for private wealth. In its July 1, 2025 family-office study, Airbus Corporate Jets reported that:
- 93 percent of surveyed U.S. family offices that own or lease business aircraft expected to upgrade within five years
- 75 percent cited a growing focus on operational costs
- 73 percent pointed to newer, more fuel-efficient models
- 61 percent cited the need for larger aircraft as more family members and staff were flying
- 28 percent cited the need for greater range
This survey was also conducted by Pureprofile, covering 100 senior executives at U.S. family offices managing an average of $3.35 billion in assets. The fieldwork took place in March 2024, with publication in July 2025. That gap matters: the data reflects pre-publication sentiment, not fresh 2025 attitudes. Taken together, the two Airbus studies describe a U.S. buyer pool that says it is ready to upgrade, with cabin size and range at the front of the conversation.
The 99.9 percent of U.S. departures claim
Airbus also argues that the ACJ TwoTwenty can cover 99.9 percent of all U.S. departures, based on its own analysis of WingX traffic data from January 2024. That figure is Airbus framing, not independent benchmarking. Even so, it captures the commercial logic behind the approval. A cabin with this much volume becomes far easier to sell into the U.S. market once it can sit on an N-numbered aircraft without regulatory friction.
How the programme reached this point
Airbus launched the ACJ TwoTwenty on October 6, 2020 as a business jet based on the A220-100. In the launch material, Airbus highlighted 73 square metres of cabin floor area, six living zones, and up to 5,650 nautical miles of range. On the same day, Airbus said the programme had already won six orders. It also said Comlux would outfit the first 15 cabins.
The industrial flow became real on January 5, 2022. That day, the first green ACJ TwoTwenty left the Airbus Canada line in Mirabel, Québec for Comlux’s completion centre in Indianapolis. Then, on April 28, 2023, Comlux delivered the first completed aircraft to FIVE Hotels and Resorts. Comlux’s May 2, 2023 announcement said the cabin had earned full EASA certification after a 14-month completion effort and that the aircraft would be based in Dubai for charter.
Since then, the programme has looked more like a real production line than a one-off showpiece. Public Comlux pages for the first delivered aircraft (9H-FIVE) and a 2024-built resale example (9H-220CJ) show the aircraft in charter and resale channels, not just in brochures. Comlux also said in its February 20, 2024 second-cabin release that it had delivered the second cabin and expected the third by the end of 2024. It added that it was targeting four to six ACJ TwoTwenty cabin deliveries annually from 2025 onward. That cadence is what gets the programme from two delivered cabins in early 2024 to the four delivered and four more in pipeline reported by AeroTime in April 2026.
For wider context on the platform beneath the business-jet derivative, see our Fliegerfaust analysis of the Airbus A220 production ramp. That broader A220 story matters here because the ACJ TwoTwenty’s cabin proposition only works if the underlying programme keeps building credibility as an aircraft family.

Conclusion: a smart, necessary win — and a pipeline that earns it
What gives Comlux America’s April 6, 2026 approval its weight is not the paperwork itself, but where it lands. The certificate arrives as the Indianapolis line scales toward a 28-aircraft backlog, new hangar bays, and a workforce that has grown by 20 percent in a single year. It arrives as the fifth ACJ TwoTwenty moves through cabin completion and two more aircraft sit on the delivery calendar. It also arrives as Airbus Corporate Jets points to a U.S. upgrade cycle that, on its own commissioned numbers, favours larger cabins and longer ranges. Read against that backdrop, this is a smart and necessary regulatory win, not a decorative one: the STC is not shouting into an empty hangar.
That said, the certificate does not create demand on its own. Comlux still needs customers willing to choose a larger, airliner-derived business jet over more familiar ultra-long-range alternatives, and Airbus still has to convert cabin admiration into signed contracts. The certificate changes the terms of that conversation, not the conversation itself.
The next real marker is the first N-numbered ACJ TwoTwenty. Until that aircraft actually appears on the FAA registry, the U.S. path is a credible plan rather than an operational record. My read is straightforward: Comlux and Airbus have done the hard regulatory work at the right moment, and the rest is now a sales problem rather than a paperwork one. Whether the ACJ TwoTwenty becomes a meaningful presence in North America or settles as a well-appointed niche depends on one thing: how quickly that first N-register example, and the deals behind it, actually materialise.
