Boeing Leadership

The Maneuvering Characteristics Augmentation System (MCAS) was added to the 737 MAX to compensate for changed handling from new engine placement. Boeing did not disclose MCAS in pilot manuals, relied on a single AOA sensor (no redundancy), and concealed it from the FAA's delegated approval process. Pilots were operating aircraft with a hidden system that could override their inputs.

• —MCAS could repeatedly push the nose of the aircraft down if its single Angle of Attack sensor malfunctioned.
• —The system was not mentioned in the 737 MAX flight crew operations manual.
• —Boeing's engineers had originally designed MCAS with a lower authority limit; internal records show the limit was expanded without returning to FAA safety analysis.
• —House Transportation Committee found Boeing's management had been aware of MCAS concerns raised internally and did not escalate.
• —FAA's delegated certification process allowed Boeing employees to approve their own safety findings on MCAS.

Lion Air Flight 610 crashed into the Java Sea minutes after takeoff from Jakarta. All 189 people aboard were killed. Investigators found that a faulty AOA sensor triggered MCAS, driving the aircraft into an unrecoverable dive. The crew had no knowledge MCAS existed and no procedure to counter it.

• —After this crash, Boeing and the FAA issued an airworthiness directive but declined to ground the 737 MAX fleet.
• —Instead, Boeing issued a bulletin referring pilots to "existing" manual stabilizer runaway procedures — which did not address a system the pilots did not know existed.
• —CEO Dennis Muilenburg personally lobbied the FAA and President Trump not to ground the aircraft, per House Committee records.
• —Five months passed between this crash and Ethiopian Airlines 302 — during which Boeing and the FAA allowed the aircraft to keep flying.

Ethiopian Airlines Flight 302 crashed six minutes after takeoff from Addis Ababa. All 157 people aboard were killed. The same failure: faulty AOA sensor, MCAS activation, fatal dive. Boeing had been aware of the Lion Air failure mode for five months and had not grounded the aircraft or fixed MCAS.

• —Total killed in both crashes: 346 people.
• —Following ET302, aviation regulators worldwide grounded the 737 MAX — the FAA was among the last to act, under intense international pressure.
• —Congressional investigators found that Boeing had known before ET302 that the MCAS software update (intended to fix the Lion Air issue) had not yet been certified.
• —Muilenburg continued to defend the aircraft's design in the weeks after ET302.

In the same period that Boeing's engineers were cutting corners on MCAS certification and safety analysis, Boeing's board authorized $43 billion in stock buybacks. This is not coincidence — both are products of the same financial incentive structure: maximize near-term stock price, minimize costs that don't show up immediately in crashes.

• —$43B in buybacks exceeded Boeing's entire R&D budget for the same period.
• —Safety-critical engineering work, including pilot simulator training development, was outsourced to lower-cost contractors (Spirit AeroSystems for fuselage; HCL Technologies and Cyient for software).
• —Dennis Muilenburg's compensation was tied heavily to stock price performance, as documented in Boeing proxy filings.
• —Boeing's board did not claw back Muilenburg's pay after the crashes.

Boeing's board removed CEO Dennis Muilenburg in December 2019 — nine months after the second crash and nearly a year after the first. He left with approximately $62 million in pension, stock awards, and deferred compensation. He was not criminally charged.

• —Muilenburg's exit package included $15.8M pension, $34.7M in incentive stock awards, and other deferred compensation per Boeing's SEC proxy filing.
• —Muilenburg testified before Congress in October 2019; senators from both parties called his performance "evasive."
• —He has not been criminally charged in connection with either crash.

In January 2021, Boeing entered a deferred prosecution agreement with the DOJ, agreeing to pay $2.5 billion and implement compliance reforms in exchange for charges being deferred. In May 2024, the DOJ determined Boeing had breached the DPA by failing to implement effective compliance programs.

• —DPA terms: $243.6M criminal fine, $500M victim compensation fund, $1.77B in airline customer compensation.
• —DOJ May 2024: Boeing had violated the DPA's compliance requirements.
• —Rather than prosecute, DOJ reached a new resolution in July 2024 — allowing Boeing to plead guilty to a single conspiracy charge and pay additional penalties.
• —Crash victims' families called the resolution inadequate and sued to block it; federal judge ultimately approved the deal over their objections.

A door plug on an Alaska Airlines 737 MAX 9 blew out at 16,000 feet, leaving a hole in the fuselage. Several passengers were partially pulled toward the opening; a child's shirt and a passenger's phone were found miles from the aircraft. No fatalities — the adjacent seat was empty per FAA safety rules. NTSB found bolts securing the door plug had not been installed during a rework at Boeing's Renton factory.

• —NTSB preliminary findings: four bolts required to secure the door plug were not installed.
• —The rework that removed and reinstalled the plug was conducted at Boeing's Renton, WA facility.
• —FAA launched a quality audit of Boeing manufacturing following the incident.
• —FAA capped Boeing's 737 MAX production rate pending quality improvements.
• —David Calhoun was Boeing's CEO when this occurred; he announced his retirement in March 2024.

John Barnett, a Boeing quality engineer who raised concerns about 787 Dreamliner manufacturing defects, died on March 9, 2024 — on the third day of his deposition in a whistleblower suit. Joshua Dean, a Spirit AeroSystems quality auditor who had reported 737 MAX defects, died on April 30, 2024. Both deaths are documented fact. Neither has been established as causally connected to Boeing.

• —John Barnett ("Swampy"), 62, was found dead in his truck in a Charleston hotel parking lot. Ruled a self-inflicted gunshot wound by the medical examiner.
• —Barnett had reported that Boeing workers were deliberately installing defective parts in the 787 to avoid rework, and that management had ignored or retaliated against his reports.
• —Joshua Dean, 45, died from a "rapidly progressing bacterial infection" approximately six weeks after departure from Spirit AeroSystems.
• —Dean had filed a whistleblower complaint with the FAA about 737 MAX manufacturing defects.
• —Editorial standard: The temporal proximity of these deaths is noted. Neither has been established as linked to Boeing's conduct. We report the facts; causation is unproven.

David Calhoun announced his retirement in March 2024, effective end of year. He departed with approximately $33 million in compensation after a tenure that included the 2024 Alaska Airlines door plug blowout, the DOJ's finding that Boeing had breached its 2021 deferred prosecution agreement, and the deaths of two whistleblowers.

• —Calhoun announced retirement the same week the Alaska Airlines 1282 NTSB preliminary findings were published.
• —Compensation details from Boeing's 2025 DEF 14A proxy filing.
• —Neither Calhoun nor Muilenburg has been criminally charged.
• —Kelly Ortberg became Boeing CEO in August 2024; recovery status is ongoing.
