## Newest cases

- [NTSB ENG24FA003](https://openairdocs.org/ntsb/ENG24FA003), Oct 18, 2023: Boeing 767-300F (N287FE), Memphis, TN, incident, minor damage. Probable cause: A high-pressure fuel leak from a gap in the bolted flange interface between the main fuel pump’s fuel crossover supply tube and the hydromechanical unit idler adapter pad, which resulted in the…
- [NTSB DCA19CA192](https://openairdocs.org/ntsb/DCA19CA192), Aug 6, 2019: Boeing 737 (N37437), SFO International Airport, CA, minor damage. Probable cause: the ramp controller directing a Boeing 737 to hold in a location that was marked for a regional jet.
- [NTSB WPR18FA143](https://openairdocs.org/ntsb/WPR18FA143), May 19, 2018: I.C.A.-Brasov IS 29D (N38ES), Avenal, CA, destroyed, 1 fatal. Probable cause: The pilot's improper installation of the wings onto the glider, which resulted in an in-flight wing separation. Contributing to the accident were the pilot's limited familiarity with the design and a…
- [NTSB WPR14LA206](https://openairdocs.org/ntsb/WPR14LA206), May 23, 2014: Williams Helicopter UH 1H (N260TA), Waitsburg, WA, substantial damage. Probable cause: An extreme vibration immediately after entering forward flight for reasons that could not be determined because postaccident examination of the helicopter did not reveal any anomalies that would have…
- [NTSB CEN14LA235](https://openairdocs.org/ntsb/CEN14LA235), May 10, 2014: Pazmany PL 4 (N44PL), Yates City, IL, substantial damage.

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.
