## Newest cases

- [NTSB WPR23LA065](https://openairdocs.org/ntsb/WPR23LA065), Dec 13, 2022: Piper PA42 (C-GZPU), Lewistown, MT, substantial damage. Probable cause: The pilot’s improper landing flare, which resulted in a hard landing. Contributing to the accident was the out of service visual glideslope indicator and snow obscuring the runway markings.
- [NTSB GAA19CA525](https://openairdocs.org/ntsb/GAA19CA525), Sep 5, 2019: Cessna 182 (N2408Q), Charleston, WV, substantial damage. Probable cause: The pilot's improper approach path at night and his misjudgment of the landing point, which resulted in landing short of the runway and impact with the runway's engineered materials arrestor system.
- [NTSB DCA19FA089](https://openairdocs.org/ntsb/DCA19FA089), Mar 4, 2019: Embraer EMB145 (N14171), Presque Isle, ME, substantial damage. Probable cause: The flight crew’s decision, due to confirmation bias, to continue the descent below the decision altitude when the runway had not been positively identified. Contributing to the accident were (1) the…
- [NTSB GAA19CA001](https://openairdocs.org/ntsb/GAA19CA001), Oct 1, 2018: Cessna 340 (N89AM), Keokuk, IA, substantial damage. Probable cause: The pilot's failure to correctly identify the runway environment during an instrument approach at night in instrument meteorological conditions because he mistook building lights for runway lights,…
- [NTSB OPS18IA015](https://openairdocs.org/ntsb/OPS18IA015), Jun 21, 2018: Boeing 747 (B-18711), Chicago, IL, incident, no damage. Probable cause: Interference with the localizer signal resulting in a Multipath condition experienced by CAL5148 while conducting an ILS CAT III (autoland) approach. This condition resulted in a runway excursion and…
- [NTSB CEN16LA097](https://openairdocs.org/ntsb/CEN16LA097), Feb 1, 2016: Piper PA 28-140 (N1572J), Sturtevant, WI, substantial damage. Probable cause: The pilot's failure to maintain a proper glidepath during a landing at dusk, which resulted in impact with a moving ground vehicle. Contributing to the accident was the inoperative precision approach…

Contributing to the accident was an inoperative precision approach path…
- [NTSB OPS10IA001](https://openairdocs.org/ntsb/OPS10IA001), Oct 19, 2009: Boeing 767 (N185DN), Atlanta Hartsfield Intl. Apt. (KATL), GA, incident, no damage. Probable cause: The flight crew’s failure to identify the correct landing surface due to fatigue. Contributing to the cause of the incident were (1) the flight crew’s decision to accept a late runway change, (2) the…
- [NTSB ERA09FA053](https://openairdocs.org/ntsb/ERA09FA053), Nov 14, 2008: Cirrus Design SR22 (N827GM), Tallahassee, FL, substantial damage, 2 fatal. Probable cause: The pilot's failure to maintain adequate airspeed on final approach, which resulted in a low-altitude aerodynamic stall and spin. Contributing to the accident was the pilot's failure to fly the…
- [NTSB SEA08LA082](https://openairdocs.org/ntsb/SEA08LA082), Feb 22, 2008: Raytheon 1900D (N305PC), Kayenta, AZ, substantial damage. Probable cause: The flight crew's failure to execute a missed approach, which resulted in a runway excursion after landing. Contributing to the accident were the inoperative lights, weather conditions below…

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.
