## Newest cases

- [NTSB DCA26LA142](https://openairdocs.org/ntsb/DCA26LA142), Feb 27, 2026: Boeing 787 (JA873A), Houston, TX, substantial damage. Probable cause: The captain’s inadvertent activation of the takeoff/go around switch at touchdown that caused an increase in the airplane pitch attitude that was not corrected before the lower fuselage contacted the…
- [NTSB DCA26LA115](https://openairdocs.org/ntsb/DCA26LA115), Feb 9, 2026: Airbus A321-271NX (N2188J), San Francisco, CA, substantial damage. Probable cause: The first officer’s excessive aft sidestick input combined with decaying airspeed during initiation of a go-around, resulting in an increase in the airplane pitch attitude and subsequent lower…
- [NTSB DCA25LA085](https://openairdocs.org/ntsb/DCA25LA085), Jan 10, 2025: Boeing 767 (N324UP), San Bernardino, CA, substantial damage. Probable cause: Encounter with windshear during landing which resulted in a tailstrike.
- [NTSB CEN23LA319](https://openairdocs.org/ntsb/CEN23LA319), Jul 22, 2023: Alisport Silent 2 Electro (N64JG), Wallis, TX, substantial damage. Probable cause: The failure of the tail boom structure due to cyclic torsion overloading as of a result of flutter in the empennage. The reason for the flutter could not be determined.
- [NTSB WPR22FA169](https://openairdocs.org/ntsb/WPR22FA169), Apr 30, 2022: Bearhawk LSA (N1908A), Kalispell, MT, substantial damage, 2 fatal. Probable cause: An excessive pitch control input for undetermined reasons while the airplane was operating above maneuvering speed, which led to a structural failure of the right wing during cruise flight.…
- [NTSB CEN20LA327](https://openairdocs.org/ntsb/CEN20LA327), Aug 3, 2020: Grumman G164 (N8105K), Alicia, AR, substantial damage. Probable cause: Inadequate maintenance of panel fasteners, which led to a side panel coming loose during takeoff and the pilot having to make a subsequent forced landing to a flooded rice field when the airplane…
- [NTSB ANC20LA064](https://openairdocs.org/ntsb/ANC20LA064), Jul 4, 2020: Piper PA22 (N3604A), Soldotna, AK, substantial damage. Probable cause: The delamination of the fabric material from the fuselage above the windscreen due to failed adhesive, which resulted in disrupted airflow and a subsequent hard landing.
- [NTSB WPR19LA171](https://openairdocs.org/ntsb/WPR19LA171), May 3, 2019: Beech 35 (N2839V), Deer Park, WA, substantial damage. Probable cause: An empennage flutter event for reasons that could not be determined based on the available information.
- [NTSB GAA18CA329](https://openairdocs.org/ntsb/GAA18CA329), Jun 7, 2018: Dobbs George Coot (N100TN), Malone, WI, substantial damage. Probable cause: The pilot’s improper decision to take off with a known structural issue, which resulted in hull damage.
- [NTSB CEN18LA099](https://openairdocs.org/ntsb/CEN18LA099), Feb 8, 2018: Beech 35 (N4654D), Batesville, AR, substantial damage. Probable cause: An in-flight control system flutter encounter during a turbulence encounter; the reason for the flutter could not be determined.

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.
