Boeing 737 MAX — MCAS, the FAA self-certification capture, and the DPA→breach→non-prosecution escape (both sides, dated)

Built 2026-06-28 from research/spec-boeing-737max.json. The corporate-safety + regulatory-capture case, and a prosecutorial-deferral variant of liability containment. Anchors Liability_Engineering; cross-links FAA, DOJ.

Frame. The 737 MAX used MCAS (a single-AoA-sensor flight-control system) hidden from pilots; two crashes killed 346 (Lion Air 610, 2018; Ethiopian 302, 2019), grounding the fleet 2019–2020. The FAA had delegated much certification to Boeing itself (ODA) — the capture. Boeing then escaped a criminal conviction through a 2021 deferred-prosecution agreement, which it breached (2024 Alaska door-plug blowout), a rejected guilty plea (Dec 2024), and finally a 2025 non-prosecution agreement; the judge dismissed the case (Nov 2025) while saying it "fails to secure the necessary accountability." Discipline. The crashes, MCAS facts, ODA, the 2024 door-plug blowout, and the 2021 DPA → 2024 breach → rejected plea → 2025 NPA → Nov-2025 dismissal are fact (NTSB/DOJ/court records). The "accountability failure / capture" vs "remediated + still-safe-aviation" readings are presented both ways with dates. Overlay; excluded from the proofs.

1. The crashes (fact)

The MAX added MCAS to compensate for larger engines' handling; it could trigger off a single angle-of-attack sensor and repeatedly push the nose down, and it was not disclosed in pilot manuals/training. Lion Air 610 (29 Oct 2018, 189 dead) and Ethiopian 302 (10 Mar 2019, 157 dead) crashed after MCAS activations the crews could not override — 346 deaths. Regulators grounded the MAX from Mar 2019 until late 2020. Fact.

2. The capture (fact)

The FAA had delegated large parts of the MAX's certification back to Boeing under its Organization Designation Authorization (ODA) — Boeing employees acting on the FAA's behalf — and key staff misled the FAA about MCAS. Post-crash reviews (DOT IG, the JATR, Congress) found the ODA self-certification + schedule/cost pressure let the MCAS risk through. Congress passed the Aircraft Certification, Safety, and Accountability Act (2020) to reform ODA. Fact; "capture vs efficient delegation" is the framing dispute.

3. The door plug (fact)

On 5 Jan 2024 a door plug blew off Alaska Airlines 1282 (a 737 MAX 9) mid-flight (no deaths). NTSB found the plug left Boeing's factory missing its retaining bolts — a quality-control/process failure tied to the Spirit AeroSystems-built fuselage. Boeing agreed to re-acquire Spirit AeroSystems (2024, ~$4.7B) to re-integrate fuselage production; the FAA capped MAX output at 38/month. Fact.

4. The criminal escape (fact, dated)

1. 7 Jan 2021 — DOJ deferred-prosecution agreement (DPA) on a charge of conspiracy to defraud the FAA: $2.5B total ($243.6M penalty + $1.77B airline compensation + $500M crash-victim fund).
2. May 2024 — DOJ found Boeing breached the DPA (the door-plug lapse occurred within the DPA term).
3. Jul 2024 — Boeing agreed to plead guilty;
4. Dec 2024 — Judge Reed O'Connor (N.D. Tex) rejected the plea as "not in the public interest" (objecting to a DEI-tinged monitor-selection clause; families also called it too lenient).
5. 23 May 2025 — DOJ + Boeing reached a non-prosecution agreement (~$1.1B + compliance program) letting Boeing avoid a guilty plea/felony conviction.
6. 6 Nov 2025 — O'Connor dismissed the case at DOJ's request, writing that the families "are correct" the deal "fails to secure the necessary accountability," but that he lacked authority to deny dismissal; families are appealing.

Fact (DOJ/court record).

5. The two sides (both ways, dated)

• (A) Accountability-failure. 346 people died from a concealed system enabled by a captured certification process, and Boeing ultimately escaped a criminal conviction via DPA→NPA despite breaching its own agreement — corporate impunity.
• (B) Boeing/remediation. Boeing paid ~$2.5B then ~$1.1B, fixed MCAS, accepted a monitor + safety investment, re-acquired Spirit to fix QC, replaced leadership (Kelly Ortberg, 2024), and aviation remains statistically very safe; the door-plug was a process lapse, not a design defect.

Both documented; the criminal-accountability outcome is the contested core.

6. The honest reading

The 737 MAX is a documented safety + regulatory-capture failure (MCAS hidden, ODA self-certification, 346 dead) followed by a documented escape from criminal conviction: a 2021 DPA, a 2024 breach, a rejected 2024 plea, a 2025 non-prosecution agreement, and a Nov-2025 dismissal in which the judge himself said accountability was not secured. For the Liability_Engineering thread it is the prosecutorial-deferral variant — neither bankruptcy two-step nor preemption, but DPA/NPA used to convert a felony exposure into fines. The remediation (payments, monitor, Spirit re-acquisition, new leadership) is real and dated; so is the families' unresolved appeal. Both sides retained with dates; overlay; excluded from the proofs.
