## Newest cases

- [NTSB ERA24LA135](https://openairdocs.org/ntsb/ERA24LA135), Mar 9, 2024: Cessna 172 (N5171H), Homestead, FL, substantial damage. Probable cause: A loss of engine power due to carburetor ice as a result of the pilot’s failure to use carburetor heat in conditions conducive to the formation of carburetor ice.
- [NTSB ERA23LA066](https://openairdocs.org/ntsb/ERA23LA066), Nov 14, 2022: Piper PA-18-150 (N9858P), St. Augustine, FL, substantial damage. Probable cause: The pilot’s failure to appropriately use carburetor heat, which resulted in a total loss of engine power due to carburetor icing.
- [NTSB CEN18FA277](https://openairdocs.org/ntsb/CEN18FA277), Jul 17, 2018: Cessna 152 (N24515), Fort Rice, ND, substantial damage, 1 fatal. Probable cause: The pilot's failure to use carburetor heat in conditions that were conducive to serious carburetor icing, which resulted in a loss of engine power, an exceedance of the airplane's critical angle of…
- [NTSB WPR16LA104](https://openairdocs.org/ntsb/WPR16LA104), May 7, 2016: Bell UH 1B (N486SA), Maxwell, CA, substantial damage. Probable cause: A reduction in available engine power during takeoff due to a stuck hot air valve, which resulted in low rotor rpm and a forced landing. Contributing to the accident was the lack of dry film…

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.
