## Newest cases

- [NTSB WPR25LA029](https://openairdocs.org/ntsb/WPR25LA029), Oct 29, 2024: Daher TBM700 (N885CA), Pinedale, WY, substantial damage. Probable cause: The pilot’s failure to ensure that the airplane was free of snow contamination before takeoff and to follow the manufacturer’s anti-icing procedure during continued snowfall, which resulted in an…
- [NTSB WPR24FA052](https://openairdocs.org/ntsb/WPR24FA052), Dec 6, 2023: Remos Remos GX (N449RA), Taylor, AZ, substantial damage. Probable cause: The pilot’s decision to attempt takeoff with frost covering the airplane’s wings, which led to an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.
- [NTSB ANC23FA003](https://openairdocs.org/ntsb/ANC23FA003), Nov 5, 2022: Airborne Windsports Edge XT-912L (N444EZ), Mokuleia, HI, substantial damage, 2 fatal. Probable cause: Structural failure of the wing for undetermined reasons, which resulted in a loss of control.
- [NTSB WPR22LA183](https://openairdocs.org/ntsb/WPR22LA183), May 14, 2022: Pyka Pelican (N605PK), Winters, CA, substantial damage. Probable cause: Delamination of the uncrewed aircraft systems’ right wing skin surfaces from the wing spar that resulted in a spin and impact with terrain.
- [NTSB ERA21LA051](https://openairdocs.org/ntsb/ERA21LA051), Nov 22, 2020: J&J Ultralights Sea-Wing (N947RC), Placida, FL, substantial damage. Probable cause: The pilot/owner’s improper preflight inspection of the weight-shift trike, which resulted in a loss of control at takeoff due to an improperly adjusted wingtip.
- [NTSB ERA20CA243](https://openairdocs.org/ntsb/ERA20CA243), Jun 7, 2020: Piper PA28 (N6958J), Greenwood, SC, substantial damage.

- [NTSB CEN20CA184](https://openairdocs.org/ntsb/CEN20CA184), May 19, 2020: Rhoads, Larry E Sopwith Baby (N41LR), Lee's Summit, MO, substantial damage. Probable cause: The airplane builder's improper installation of the lower right wing which resulted in an uncommanded left roll and the subsequent loss of control.
- [NTSB WPR18FA195](https://openairdocs.org/ntsb/WPR18FA195), Jul 13, 2018: Cessna 172 (N24442), Deer Park, WA, substantial damage, 3 fatal. Probable cause: An in-flight breakup as a result of the airplane exceeding the structural strength of the airplane during a rapid descent that the flight instructor was unable to recover from following a collision…
- [NTSB CEN17LA224](https://openairdocs.org/ntsb/CEN17LA224), Jun 7, 2017: Mckenna SD-1A (N31313), Juneau, WI, substantial damage.

- [NTSB ANC16LA034](https://openairdocs.org/ntsb/ANC16LA034), Jun 19, 2016: De Havilland DHC3 (N104BM), Homer, AK, substantial damage. Probable cause: An in-flight collision with a bald eagle, which resulted in substantial damage to the left wing.

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.
