## Newest cases

- [NTSB CEN26LA315](https://openairdocs.org/ntsb/CEN26LA315), Sep 10, 2026: Progressive Aerodyne Searey (N80515), DeQuincy, LA, substantial damage. Probable cause: The pilot’s failure to maintain directional control during takeoff after encountering a wind gust. Contributing to the accident was nearby convective activity.
- [NTSB ERA26LA336](https://openairdocs.org/ntsb/ERA26LA336), Sep 9, 2026: Piper PA-32-300 (N4056W), West Kingston, RI, substantial damage. Probable cause: The pilot’s failure to bring the airplane to a stop on the available runway, which resulted in a runway excursion.
- [NTSB ERA26LA327](https://openairdocs.org/ntsb/ERA26LA327), Sep 3, 2026: Robinson Helicopter R22 Beta (N276SH), McMinnville, TN, substantial damage. Probable cause: The flight instructor’s delayed remedial action during a practice autorotation, which resulted in a hard landing.
- [NTSB ERA26LA323](https://openairdocs.org/ntsb/ERA26LA323), Sep 1, 2026: Mooney M-20 (N3706N), Stanfield, NC, substantial damage. Probable cause: The pilot’s failure to adequately manage the available fuel onboard the airplane, which resulted in a total loss of power due to fuel starvation and a forced landing on uneven terrain.

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.
