## Newest cases

- [NTSB CEN16LA230](https://openairdocs.org/ntsb/CEN16LA230), Jun 18, 2016: Glaeser Nieuport 11 (N124TG), Gardner, KS, substantial damage. Probable cause: The pilot's diverted attention during the approach for the precautionary landing, which resulted in low airspeed, an exceedance of the airplane’s critical angle of attack, and a subsequent…
- [NTSB CEN10LA090](https://openairdocs.org/ntsb/CEN10LA090), Jan 6, 2010: Beech C-99 (N206AV), Kearney, NE, substantial damage. Probable cause: The failure of the pilot to maintain adequate airspeed during the approach resulting in a stall. Contributing to the accident was the accumulation of structural icing during the flight.
- [NTSB DCA09MA027](https://openairdocs.org/ntsb/DCA09MA027), Feb 13, 2009: Bombardier DHC-8-402 (N200WQ), Clarence Center, NY, destroyed, 50 fatal. Probable cause: The captain’s inappropriate response to the activation of the stick shaker, which led to an aerodynamic stall from which the airplane did not recover. Contributing to the accident were (1) the flight…
- [NTSB NYC08FA133](https://openairdocs.org/ntsb/NYC08FA133), Mar 13, 2008: Cessna 172 (N284SP), Indiantown, FL, substantial damage, 4 fatal. Probable cause: The pilot's failure to maintain an adequate airspeed while maneuvering at low altitude. Contributing to the accident was the overweight condition of the airplane and the inoperative stall warning…

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.
