## Newest cases

- [NTSB CEN11LA050](https://openairdocs.org/ntsb/CEN11LA050), Nov 1, 2010: Mcfarland Bill Challenger II (N448WM), Praire Du Sac, WI, substantial damage, 1 fatal. Probable cause: The separation of the fuselage-mounted wing strut attachment fitting for an undetermined reason, which resulted in the separation of the left wing of the airplane.
- [NTSB WPR10FA211](https://openairdocs.org/ntsb/WPR10FA211), Apr 21, 2010: AirBorne WindSport Edge XT-912-L (N34TH), Captain Cook, HI, substantial damage, 2 fatal. Probable cause: The pilot’s intentional in-flight maneuvers that exceeded the structural limits of the aircraft, which resulted in structural failure of the wings.

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.
