Federal prosecutors charged Boeing with criminal fraud. The company violated that agreement. Then a door panel fell off a new plane at 16,000 feet. That sequence happened in roughly four years, and it followed two fatal crashes that killed 346 people.
If you are checking whether your next flight is on a Boeing aircraft, five years of NTSB reports, FAA audits, congressional hearings, and federal court records give you a clear answer. Here is what they found.

The 737 MAX 8: Two Crashes, One Concealed System
On October 29, 2018, Lion Air Flight 610 crashed into the Java Sea 13 minutes after leaving Jakarta, Indonesia. All 189 people on board were killed. On March 10, 2019, Ethiopian Airlines Flight 302 crashed six minutes after takeoff from Addis Ababa, Ethiopia. All 157 people on board died.
Both aircraft were Boeing 737 MAX 8s. Both were nearly new. Both came down because of the same flight control system, called MCAS.
Why MCAS existed at all: Boeing built the 737 MAX with larger, heavier engines positioned higher and further forward on the wing than previous generations. That engine placement caused the aircraft’s nose to pitch upward unexpectedly at certain speeds. MCAS, the Maneuvering Characteristics Augmentation System, was written to automatically push the nose back down when sensors detected the problem.
Why it killed 346 people:
- MCAS was connected to only one angle-of-attack sensor, despite the aircraft having two
- When that single sensor failed and sent false data, MCAS activated repeatedly, forcing the nose into an unrecoverable dive
- Flight crews on both aircraft had never been told MCAS existed — Boeing had removed all references to it from pilot training documents
- The FAA approved those training documents without knowing the full scope of what MCAS could do
The concealment was documented. Congressional investigators recovered internal Boeing emails showing a senior test pilot boasted about “jedi-mind tricking” FAA evaluators into approving materials that omitted MCAS entirely. By December 2018, three months after the Lion Air crash, the FAA had privately estimated that an unfixed MCAS could cause 15 additional crashes over 30 years. Boeing had still not issued a fix when Ethiopian Airlines Flight 302 went down in March 2019.
On March 13, 2019, the FAA grounded the entire 737 MAX fleet. All 387 aircraft across 59 airlines worldwide were out of service. The grounding lasted 21 months.
What Boeing Changed After the Grounding
Before the FAA cleared the MAX to return to service in November 2020, Boeing was required to make verified engineering and training changes:
- MCAS now reads from both sensors and cross-checks the data before activating — the single-point-of-failure that caused both crashes no longer exists
- MCAS fires only once per event, not repeatedly as it did in both accident flights
- Pilot override is guaranteed — the system’s authority is capped so any pilot can counteract it manually using the control column alone
- Full-motion simulator training on MCAS is now mandatory for every pilot flying the MAX
- The FAA retained certification authority for each individual aircraft rather than delegating approvals back to Boeing
Since December 2020, the 737 MAX 8 has recorded no crashes and no MCAS-related incidents across more than 2,200 aircraft deliveries. The January 2024 Alaska Airlines incident involved the MAX 9 and was a manufacturing defect, entirely separate from the flight control software.
The 737 MAX 9: When the Door Came Off Mid-Flight
On January 5, 2024, Alaska Airlines Flight 1282 was climbing out of Portland, Oregon, when a door-sized panel covering an unused emergency exit blew off the fuselage. The plane was at 16,000 feet. Rapid decompression hit the cabin. No one was killed, partly because the two seats directly beside the opening happened to be unoccupied.
The NTSB’s investigation, concluded in June 2025, found that four bolts meant to secure the door plug were missing when Boeing delivered the aircraft to Alaska Airlines in October 2023. Workers had removed the plug during a factory repair, never logged the removal, reinstalled the panel without the bolts, and no quality inspection was ever performed afterward.
Workers told investigators they had been pressured to work too fast and given tasks they were not qualified for. Of the 24-person door installation team, only one person had ever done that specific job before. That person was on vacation when the work was done on this aircraft.
“An accident like this only happens when there are multiple system failures,” NTSB Chair Jennifer Homendy said at the June 2025 hearing.
The FAA imposed a production cap on all 737 MAX variants. The Department of Justice launched a criminal investigation. Boeing CEO Dave Calhoun announced his resignation months after the incident.
The Boeing 787 Dreamliner: A Longer Record of Manufacturing Failures
The 787 is not the 737 MAX. It has not had a crash caused by a design flaw. But it has accumulated a documented history of production quality failures that stretches back to 2013, and the people who raised alarms about it paid a serious personal price.
The documented timeline:
- 2013 — A global grounding of all 787s after lithium-ion battery fires and smoke incidents on multiple aircraft
- 2021 to 2022 — Boeing halted 787 deliveries for roughly a year after the FAA flagged manufacturing defects, including improperly joined fuselage sections
- 2023 — A second delivery halt for similar quality control violations
- January 2024 — Boeing quality engineer Sam Salehpour filed a formal FAA complaint alleging factory workers routinely forced fuselage sections together that did not properly align, leaving drilling debris inside structural joints. He had raised these concerns internally for three years starting in 2020, was told not to slow the production line, and said he received physical threats for speaking up
- 2024 — A U.S. Senate investigation found Boeing workers had falsified inspection records on 787 aircraft, logging mandatory electrical grounding checks as completed when they had never been conducted
The Whistleblower Who Died During His Deposition
John Barnett spent 32 years at Boeing, the final seven as a quality control manager at the South Carolina facility where 787s are assembled. He documented what he described as a 25 percent failure rate in emergency oxygen systems, stray metal shavings near electrical wiring, and managers who actively discouraged defect reporting. He resigned in 2017 under the weight of the retaliation he said he faced, and filed a whistleblower lawsuit against the company.
In early March 2024, he traveled from his home in Louisiana to Charleston, South Carolina, to give deposition testimony in that case. On March 9, 2024, he did not appear for his third day of questioning. His attorneys called the hotel. A welfare check found him in his locked truck in the parking lot, dead from a gunshot wound to his head. He was 62.
A notebook on the passenger seat read: “I pray Boeing pays.”
The Charleston Police Department conducted a full investigation and ruled the death a suicide. Medical records showed Barnett had suffered from PTSD, chronic anxiety, and distress tied directly to years of fighting his case against Boeing. His family subsequently filed a wrongful death lawsuit against the company.
Two months after Barnett’s death, Joshua Dean, 45, a quality auditor at Boeing supplier Spirit AeroSystems who had also flagged production defects, died from a MRSA bacterial infection.
The Air India Crash and What It Does and Doesn’t Tell Us
On June 12, 2025, an Air India Boeing 787-8 crashed 32 seconds after takeoff from Ahmedabad, India, killing 241 of the 242 people on board. It was the first fatal accident in the 787’s history across over 18 million flight hours.
Preliminary findings show the aircraft’s engine fuel control switches moved from RUN to CUTOFF three seconds after liftoff, cutting power to both engines. U.S. investigators have indicated the evidence points toward deliberate action by the captain. The investigation remains open. Boeing’s manufacturing has not been identified as a contributing factor in this specific crash.
The Criminal Fraud Case: What Most Coverage Misses
The legal case against Boeing runs far beyond headlines about a settlement.
- January 2021 — Boeing signs a Deferred Prosecution Agreement with the DOJ. Total settlement: $2.5 billion, including a $243.6 million criminal fine, $1.77 billion to airlines whose fleets were grounded, and $500 million to families of the 346 victims. The criminal fraud charge is deferred for three years, contingent on Boeing fulfilling compliance obligations
- January 5, 2024 — The Alaska Airlines door plug blows off. The DPA was scheduled to expire two days later
- May 2024 — DOJ declares Boeing violated the DPA by failing to implement the required compliance and ethics programs
- July 2024 — Boeing agrees to plead guilty to criminal fraud
- December 2024 — A federal judge rejects the proposed plea agreement
- May 2025 — DOJ and Boeing reach a Non-Prosecution Agreement. Boeing agrees to pay or invest $1.1 billion in fines, victim compensation, and safety programs. Criminal charges are dropped
Families of the 346 crash victims called the final agreement a “sweetheart deal.” One family member said publicly: “The message sent to corporate America is: don’t worry about killing your customers.”
The 737 MAX 7 and MAX 10: Never Certified, Never Flown Commercially
Two 737 MAX variants have never carried a single paying passenger and are not approved for commercial operations as of March 2026.
The MAX 7 and MAX 10 have been held up by a persistent problem with their engine anti-ice systems, and by a congressionally mandated upgrade to the crew alerting system, a reform passed specifically because of the MAX 8 crashes. Boeing CEO Kelly Ortberg confirmed in January 2026 that the company has a final design fix for the anti-ice issue, but FAA certification for both variants is not expected before late 2026 at the earliest.
How to Check What Aircraft You Are Flying
Most booking platforms show the aircraft type during checkout, below the flight segment details. For more detail:
- Google Flights — lists the aircraft model at the search stage for each flight segment
- FlightAware — enter a flight number to see the registered aircraft type and its history
- FlightRadar24 — shows which specific plane has operated a given route historically
- Airline websites — “Manage Booking” or “Flight Status” sections show the scheduled equipment
Aircraft assignments can change, particularly on flights booked months in advance. Checking 48 to 72 hours before departure gives the most accurate picture.
U.S. Airlines That Operate No Boeing Aircraft
| Airline | Fleet |
|---|---|
| JetBlue | Airbus and Embraer only |
| Frontier Airlines | Airbus only |
| Allegiant Air | Airbus only |
| Breeze Airways | Airbus and Embraer only |
Note: Spirit Airlines, which previously operated an all-Airbus fleet, shut down entirely in January 2025.
What the Record Actually Shows
Boeing’s commercial aviation safety record since 2018 is the most scrutinized in the industry’s modern history. Two crashes caused by software the company deliberately kept from pilots. A door panel off a new aircraft because workers were pressured past the point of basic quality control. Criminal fraud charges deferred, violated, proposed for guilty plea, rejected by a judge, and ultimately settled without a conviction. Quality managers who spent years raising alarms before one died the morning he was supposed to finish his deposition.
The Boeing aircraft with the clearest documented concerns are the 737 MAX 8 and 737 MAX 9, followed by the 787 Dreamliner on the basis of its manufacturing history. The 737 MAX 7 and MAX 10 have never been certified for commercial service and are not on any scheduled route.
The MCAS software that caused 346 deaths has been technically redesigned and has not caused an incident since the MAX returned to service in December 2020. Whether Boeing’s broader safety culture has genuinely changed is a question regulators, investigators, and the flying public are still in the middle of answering.
