## Newest cases

- [NTSB CEN18LA340](https://openairdocs.org/ntsb/CEN18LA340), Aug 20, 2018: Beech B36TC (N6860W), LaPorte, TX, destroyed. Probable cause: The loss of engine power due to a torn intercooler hose that resulted in an overly rich fuel mixture, which, when combined with the pilot's activation of the auxiliary fuel pump, flooded the engine.
- [NTSB ENG12IA010](https://openairdocs.org/ntsb/ENG12IA010), Feb 8, 2012: Boeing 767 (N360AA), Jamaica, NY, incident, no damage. Probable cause: The failure of the American Airlines aviation maintenance technicians to properly reassemble the two-piece bracket and spray shield on the integrated drive generator fuel-oil heat exchanger that…

Probable cause: An accumulation of ice in the fuel system, which formed from the water normally present in jet fuel during commonly encountered flight conditions, which accreted and released, restricting the fuel…

NTSB has coded findings and defining events since 2008; earlier cases used its older occurrence and cause codes and aren't counted.

Findings: https://openairdocs.org/ntsb-findings.md. Defining events: https://openairdocs.org/ntsb-events.md. Phases of flight: https://openairdocs.org/ntsb-phases.md. Every investigation, filtered by finding, event, phase, state, year or model: https://openairdocs.org/ntsb.md (for example ?state=MI&fatal=1).

NTSB's definitions: Accident and incident, 49 CFR 830.2 (https://www.ecfr.gov/current/title-49/subtitle-B/chapter-VIII/part-830/subpart-A/section-830.2), CICTT occurrence categories (PDF) (https://www.ntsb.gov/safety/data/Documents/datafiles/OccurrenceCategoryDefinitions.pdf), CICTT phases of flight (PDF) (https://www.ntsb.gov/safety/data/Documents/datafiles/PhaseofFlightDefinitions.pdf), and NTSB coding manual, before 2008 (PDF) (https://www.ntsb.gov/GILS/Documents/codman.pdf). NTSB publishes no definitions for its findings, only their names.
