## Newest cases

- [NTSB CEN26LA169](https://openairdocs.org/ntsb/CEN26LA169), Apr 19, 2026: Luscombe 8E (N1398K), Meeker, CO, substantial damage. Probable cause: The pilot’s inability to maintain climb performance and clearance from terrain due to the airplane’s encounter with windshear during takeoff.
- [NTSB CEN26LA159](https://openairdocs.org/ntsb/CEN26LA159), Apr 5, 2026: Piper PA46 (N95AG), Burke, TX, substantial damage. Probable cause: The airplane’s encounter with unexpected low-level wind shear during final approach, which resulted in a hard impact with the runway.
- [NTSB CEN26LA127](https://openairdocs.org/ntsb/CEN26LA127), Feb 26, 2026: Raytheon B36TC (N2251Q), Durango, CO, substantial damage. Probable cause: The pilot’s improper landing flare and subsequent loss of directional control while attempting to land during high crosswind conditions.
- [NTSB ANC26LA010](https://openairdocs.org/ntsb/ANC26LA010), Jan 16, 2026: Beech 65-A90-1 (N918MR), Anchorage, AK, substantial damage. Probable cause: The pilot’s failure to attain proper flare during landing resulting in a hard landing short of the runway threshold. Contributing to the accident were gusting wind conditions.
- [NTSB CEN26LA027](https://openairdocs.org/ntsb/CEN26LA027), Oct 21, 2025: Robinson Helicopter R22 (N74583), Springfield, MO, substantial damage. Probable cause: The pilot’s failure to maintain directional control and the flight instructor’s lack of proper remedial action during the practice autorotation that resulted in the helicopter impacting terrain.…
- [NTSB ANC25LA107](https://openairdocs.org/ntsb/ANC25LA107), Sep 16, 2025: David Hunter Danchini CUB (N798AK), Tyonek, AK, substantial damage. Probable cause: The pilot’s failure to maintain directional control of the airplane during the landing roll, in gusting crosswind conditions.
- [NTSB WPR25LA198](https://openairdocs.org/ntsb/WPR25LA198), Jun 28, 2025: Republic RC-3 (N6759K), Coolin, ID, substantial damage. Probable cause: The pilot’s failure to maintain control of the airplane and exceedance of the critical angle of attack during takeoff in windy conditions which resulted in a subsequent hard landing.
- [NTSB CEN25LA134](https://openairdocs.org/ntsb/CEN25LA134), Mar 20, 2025: Cessna 152 (N68332), Denton, TX, substantial damage. Probable cause: The pilot’s improper landing flare and subsequent improper recovery from a bounced landing. Contributing to the accident was the gusty crosswind and windshear during landing.
- [NTSB CEN25LA088](https://openairdocs.org/ntsb/CEN25LA088), Jan 27, 2025: Cessna 172S (N51387), Air Force Academy, CO, substantial damage. Probable cause: The pilot’s failure to maintain airplane control during final approach after encountering an unexpected windshear.
- [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 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.
