## Newest cases

- [NTSB ERA25LA102](https://openairdocs.org/ntsb/ERA25LA102), Jan 20, 2025: Daniel A Robinson High 6 Berkut 540 (N976DR), Orlando, FL, substantial damage. Probable cause: The pilot’s failure to verify the canopy latches were in the locked position prior to takeoff.
- [NTSB ERA21LA396](https://openairdocs.org/ntsb/ERA21LA396), Mar 22, 2021: Sonex Waiex (N220JD), Doylestown, PA, substantial damage. Probable cause: The pilot’s failure to maintain a proper glidepath during landing. Contributing to the accident was his failure to ensure the canopy locks were properly configured prior to flight.
- [NTSB GAA20CA092](https://openairdocs.org/ntsb/GAA20CA092), Nov 23, 2019: Czech Aircraft Works Spol Sro Sportscruiser (N595SC), Lamar, CO, substantial damage. Probable cause: The pilot's distraction due to an open canopy during final approach, which resulted in a loss of altitude and ground impact short of the runway.
- [NTSB GAA20CA027](https://openairdocs.org/ntsb/GAA20CA027), Oct 11, 2019: Zenith Zenith 601XLB (N235JH), Gastonia, NC, substantial damage. Probable cause: The pilot's failure to latch the canopy before departure, which resulted in the canopy opening and the subsequent loss of airplane control.
- [NTSB WPR19LA088](https://openairdocs.org/ntsb/WPR19LA088), Feb 10, 2019: Lancair IV (N549CJ), Laramie, WY, substantial damage. Probable cause: An environmental stress cracking failure of the acrylic windshield, which resulted in a rapid decompression during cruise flight.

- [NTSB ERA11FA287](https://openairdocs.org/ntsb/ERA11FA287), May 7, 2011: Czech Sport Piper Sport (N420PS), Spring Hill, FL, substantial damage, 1 fatal. Probable cause: The pilot's inadvertent application of control inputs that resulted in rapid, right-rolling, negative g-forces during night cruise flight and his subsequent ejection from the airplane.

- [NTSB CEN11CA242](https://openairdocs.org/ntsb/CEN11CA242), Mar 21, 2011: Darrow Stephen A Aventura (N1317L), Ferris, TX, substantial damage. Probable cause: The pilot’s loss of aircraft control during landing.

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.
