## Newest cases

- [NTSB CEN25LA086](https://openairdocs.org/ntsb/CEN25LA086), Jan 16, 2025: American Champion 7ECA (N798L), Longview, TX, incident, substantial damage. Probable cause: The failure of the lower hinge barrel due to fatigue cracking. Contributing to the failure of the lower hinge barrel was increased stress from end face contact likely associated with worn bushings or…
- [NTSB CEN24LA162](https://openairdocs.org/ntsb/CEN24LA162), Apr 12, 2024: American Champion 7ECA (N793L), Longview, TX, substantial damage. Probable cause: The rudder post’s failure due to corrosion fatigue. Contributing to the accident were the misalignment of the rudder hinge components, which produced mechanical binding and elevated localized stress,…
- [NTSB WPR10LA306](https://openairdocs.org/ntsb/WPR10LA306), Jun 19, 2010: Luscombe 11A (N1606B), Merced, CA, substantial damage. Probable cause: The pilot’s inability to maintain airplane control during cruise flight due to the failure of the elevator trim tab as a result of missing hardware for the elevator control cable bellcrank to…

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.
