## Newest cases

- [NTSB WPR24FA196](https://openairdocs.org/ntsb/WPR24FA196), Jun 15, 2024: Lockheed 12A (N93R), Chino, CA, substantial damage, 2 fatal. Probable cause: The pilot’s exceedance of the airplane’s critical angle of attack during the initial climb, which resulted in an aerodynamic stall at an altitude insufficient for recovery. Contributing to the…
- [NTSB CEN16LA259](https://openairdocs.org/ntsb/CEN16LA259), Jul 8, 2016: Cessna 152 (N5331B), Bridgeport, TX, substantial damage. Probable cause: The pilot's unstabilized approach and uneven braking due to insufficient runway remaining, which resulted in a loss of directional control during landing. Contributing to the accident was the bound…
- [NTSB ERA15FA203](https://openairdocs.org/ntsb/ERA15FA203), May 3, 2015: Cessna 172 (N3969L), Penn Yan, NY, substantial damage, 1 fatal. Probable cause: The student pilot's failure to maintain airplane control during the initial climb. Contributing to the accident was the student's inappropriate configuration of the airplane's wing flaps for the…
- [NTSB WPR13CA018](https://openairdocs.org/ntsb/WPR13CA018), Oct 18, 2012: Albright Stan Kitfox Super Sport (N960WM), Twin Bridges, MT, substantial damage. Probable cause: The airplane builder’s failure to rig the flight controls correctly, which resulted in a loss of control after takeoff.
- [NTSB ANC11LA041](https://openairdocs.org/ntsb/ANC11LA041), Jun 2, 2011: Eclipse EA500 (N168TT), Nome, AK, substantial damage. Probable cause: The pilot landed without lowering the landing gear. Contributing to the accident was the pilot's decision to fly the airplane with an inoperative wing flap system.
- [NTSB ERA09IA009](https://openairdocs.org/ntsb/ERA09IA009), Oct 5, 2008: Cirrus Design SR22 (N101CD), Lakeland, FL, incident, minor damage. Probable cause: A failure of the flap actuator rod end due to low stress, high cycle fatigue, and subsequent overstress failure.

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.
