## Newest cases

- [NTSB CEN24LA004](https://openairdocs.org/ntsb/CEN24LA004), Oct 1, 2023: Robinson Helicopter R44 (N379SH), Hochatown, OK, substantial damage. Probable cause: A total loss of engine power during a practice autorotation due to the improper engine idle setting and rigging of the carburetor heat control which resulted in a hard landing.
- [NTSB CEN19FA029](https://openairdocs.org/ntsb/CEN19FA029), Nov 17, 2018: Beech 55 (N4817M), Liberal, KS, substantial damage, 2 fatal. Probable cause: The pilot's improper decision to fly in an area where moderate icing conditions were forecasted in an airplane that was not certified for such conditions, and in the effort to get out of the icing…
- [NTSB GAA18CA503](https://openairdocs.org/ntsb/GAA18CA503), Aug 22, 2018: Champion 8GCBC (N88287), Elberta, AL, substantial damage. Probable cause: The pilot's failure to use carburetor heat during a low-power setting approach in conditions conducive to carburetor icing, which resulted in a partial loss of engine power.
- [NTSB WPR14LA208](https://openairdocs.org/ntsb/WPR14LA208), May 24, 2014: Cessna 182P (N21048), Mammoth Lakes, CA, substantial damage. Probable cause: The total loss of engine power due to carburetor icing, which resulted from the pilot’s failure to use carburetor heat in cruise flight while operating in an area conducive to carburetor icing.

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.
