Boeing vs Airbus: An Ethics Comparison Built From Court Filings

Boeing vs Airbus: An Ethics Comparison Built From Court Filings

Boeing and Airbus form one of the tightest duopolies in modern industry. If you fly, you almost certainly fly on one of them. If you hold an index fund, you almost certainly own one of them.

Most comparisons of the two companies focus on order books and delivery numbers. This one focuses on conduct.

Mashinii scores companies using adversarial evidence: court filings, regulatory enforcement actions, settlement documents, and investigative reporting. Not sustainability brochures. On that evidence, Boeing and Airbus look far less alike than their aircraft do.

How the two companies score

Each company is scored across eleven values on a scale where negative numbers reflect documented harm and positive numbers reflect documented good conduct. Here is the full side-by-side.

Two patterns stand out. Boeing's worst scores cluster around integrity and safety. Airbus carries its own scars, but on the values where the two diverge most, the evidence runs in one direction.

The integrity gap is the headline

The single largest difference in the table sits under Honest & Fair Business: Boeing at -60, Airbus at -20.

Boeing's score is built on one of the most heavily documented corporate accountability records of the past decade. After the two 737 MAX crashes that killed 346 people, the US Department of Justice charged Boeing with conspiracy to defraud the Federal Aviation Administration. The company entered a deferred prosecution agreement in 2021, admitting that its employees had misled regulators about the MCAS flight control software.

That agreement did not end the matter. Prosecutors later found that Boeing had breached its terms, reopening the question of criminal liability and keeping the company under court supervision for years.

Airbus is not clean on this value, and the score reflects it. In 2020 the company agreed to pay roughly 3.6 billion euros to settle bribery and corruption investigations with authorities in France, the UK, and the US. It remains the largest corruption settlement on record.

So why the 40-point gap? The Airbus case concerned bribery to win sales, resolved through cooperation with prosecutors and a compliance overhaul that investigating agencies publicly credited. The Boeing case concerned deceiving a safety regulator about a system implicated in two fatal crashes, followed by a breach of the very agreement meant to resolve it. Court records treat those as different categories of misconduct, and so do we.

Safety culture: a 50-point divide

The second clearest split is Safe & Smart Tech, where Airbus scores +20 and Boeing scores -30.

Boeing's record here is a matter of public regulatory action, not opinion. In January 2024 a door plug blew out of a 737 MAX 9 in flight, and the FAA responded by capping Boeing's production rates while it audited the company's manufacturing and quality systems. A regulator restricting how many aircraft a manufacturer may build is an extraordinary intervention.

Layered on top are the whistleblower cases. Multiple current and former Boeing employees have testified, in congressional hearings and legal proceedings, about quality lapses and pressure to prioritise schedule over inspection. Whistleblower testimony given under oath is exactly the kind of adversarial evidence Mashinii weights heavily, because it carries legal risk for the person making the claim.

Airbus's positive score is not a halo. It reflects a documented record of safety engineering and the absence of comparable enforcement actions against its commercial aircraft production. The company has had incidents, as every manufacturer has, but no regulator has capped its output or charged it with deceiving a safety agency.

Where the two companies look the same

It would be a mistake to read this comparison as Airbus the saint and Boeing the sinner. On several values the two are nearly identical, and not in a good way.

Both score heavily negative on No War No Weapons: Boeing at -70, Airbus at -50. Both run substantial defence divisions producing military aircraft, missiles, and weapons systems. An investor screening out arms exposure cannot hold either company, full stop. We cover this dynamic across the sector in our review of how defence stocks score on ethics.

Both also score -20 on Fair Pay & Worker Respect, reflecting documented labour disputes and workforce grievances on each side of the Atlantic. And both are negative on Planet-Friendly Business, which is hard to avoid when your product burns kerosene at altitude.

Airbus actually scores worse than Boeing on two values: Fair Trade & Ethical Sourcing at -30 versus -20, and Zero Waste & Sustainable Products at -20 versus Boeing's 0. The supply chain findings cut both ways.

So, is Boeing ethical?

On the evidence in court filings and regulatory dockets, Boeing currently carries one of the weakest integrity records of any large industrial company. A -60 on honest business conduct and a -30 on technology safety are not artefacts of methodology; they trace to a criminal charge, a breached prosecution agreement, an FAA production cap, and sworn whistleblower testimony.

Airbus is the stronger of the two on conduct, but it is not a clean company. A record bribery settlement, negative sourcing scores, and a large weapons business keep it well short of anything resembling an ethical benchmark.

The honest summary: this is a comparison between a company with a serious documented integrity problem and a company with a serious but partially remediated one. For values-driven investors, the difference matters. For investors who screen out weapons entirely, it may not.

Check what you actually own

Most investors hold Boeing without ever choosing it. It sits inside S&P 500 trackers, target-date funds, and aerospace ETFs by default, a point we unpack in Boeing in your retirement fund.

If you want to know whether your portfolio contains Boeing, Airbus, or both, and what that exposure means against your own values, you can audit your portfolio in a few minutes. Or search any company to see its full evidence-based score, value by value.

The scores above will move as new filings land. The evidence behind them is public. We just read it so you do not have to.
