How accidents become rules.

For every Federal Register document the FAA has issued — final rules, NPRMs, ADs, notices — we mine the body text for citations of NTSB Safety Recommendations (A-XX-NNN) and CAROL event IDs. The deterministic linkage shows which accidents produced which regulations, in the agency's own words.

The recs that bent the system.

NTSB Safety Recommendations ranked by how many Federal Register rules cite them. A rec with 30+ citations didn't move once — it shaped years of follow-on rulemaking. The full chain — accident → recommendation → rule — completes when a rec resolves to its originating event in the NTSB database. 330 of these top recs trace to a specific accident.

TO THE FEDERAL AVIATION ADMINISTRATION: Develop abuse tests that subject a single cell within a permanently installed, rechargeable lithium-ion battery to thermal runaway and demonstrate that the battery installation mitigates all hazardous effects of propagation to other cells and the release of electrolyte, fire, or explosive debris outside the battery case. The tests should replicate the battery installation on the aircraft and be conducted under conditions that produce the most severe outcome.

TO THE FEDERAL AVIATION ADMINISTRATION: Require the development of and implementation of design or operational changes that will preclude the operation of transport-category airplanes with explosive fuel-air mixtures in the fuel tank: (a) significant consideration should be given to the development of airplane design modifications, such as nitrogen-inerting systems & the addition of insulation between heat-generating equipment & fuel tanks. Appropriate modifications should apply to newly certificated airplanes &, where feasible to existing airplanes.

THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: AMEND 14 CFR 139.49 TO PRESCRIBE A MINIMUM LIST OF RESCUE/SUPPORT EQUIPMENT TO BE CARRIED ON EACH CRASH/FIRE/ RESCUE VEHICLE WHICH IS COMMENSURATE WITH THE AIRPORT'S INDEX OF FIREFIGHTING AND RESCUE SERVICE.

02 · NTSB events named in rules

Accidents the FAA cited by name.

Federal Register documents almost always cite Safety Recommendations rather than specific events. When the agency names an event ID directly, it's usually because the accident itself reshaped policy — Comair 5191, Asiana 214, Atlas Air 3591, Colgan 3407.

Method.

What we mine

Every Federal Register document published by the FAA from 1995 forward — final rules, proposed rules, ADs, advisory circulars referenced in rules, technical amendments, notices. Body text is sharded by year (V8 string-limit workaround) and parsed for two patterns:

  • A-XX-NNN / M-XX-NNN / etc. — NTSB Safety Recommendations across all five modes (Aviation, Marine, Highway, Pipeline, Rail).
  • ANC88LA152-shape strings — CAROL event IDs, validated against our 178k known-event index.

Validation

Event-ID matches are filtered against the actual NTSB CAROL index — typo'd or hallucinated event IDs in rule text get rejected. 3 candidates were dropped this way.

The CAROL prefix block-list excludes obvious shape collisions (FAA-prefixed RIN numbers, NHTSA codes, etc.) so we don't pollute the trail with false positives.

Rec → event linkage

The third edge — rec issued in response to event — comes from the NTSB Safety Recommendations dataset (CAROL safetyrecs collection, 11,547 recs ingested across all five modes (Aviation, Marine, Highway, Pipeline, Rail), 2,244 with originating events). Each rec carries its NtsbNo directly from the NTSB record. The full chain — accident → recommendation → rule — resolves whenever a cited rec exists in the NTSB database. The remaining ~19% of cited recs predate CAROL's coverage (NTSB recs from the 1960s and earlier exist in archived documents but not the live database) — those rows are flagged pre-CAROL coverage and link out to NTSB's search.

Not editorial

Every link here is a verbatim citation in the agency's own text — no AI inference, no "related" guesses. If the FedReg document literally contains the rec ID, it shows up. If it doesn't, it doesn't.
