## Newest cases

- [NTSB CEN23FA285](https://openairdocs.org/ntsb/CEN23FA285), Jul 6, 2023: Piper PA-60-601P (N100PB), Burlington, CO, destroyed, 1 fatal. Probable cause: The pilot’s visual flight rules flight into instrument meteorological conditions, which resulted in a loss of control in flight and subsequent impact with terrain.
- [NTSB DCA19CA170](https://openairdocs.org/ntsb/DCA19CA170), Jun 21, 2019: Boeing CV2 (N243XT), Beeville, TX, substantial damage. Probable cause: A higher than expected and accounted for crosswind which initiated a lateral deviation, and resulted in the aircraft reaching the limits of the geo-fence area triggering a contingency forced landing.
- [NTSB SEA08LA095](https://openairdocs.org/ntsb/SEA08LA095), Mar 26, 2008: Piper PA-28-181 (N432RM), Bridger, MT, substantial damage. Probable cause: The pilot failed to maintain situational awareness during the flight. Contributing to the accident were the dark night, the pilot's failure to follow approved navigational procedures for the flight,…

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.
