## Newest cases

- [NTSB DCA25LA025](https://openairdocs.org/ntsb/DCA25LA025), Oct 24, 2024: Boeing 737-9 (N27515), Houston, TX, substantial damage. Probable cause: Brake application before all three landing gears were on the ground, which caused the failure of the right main landing gear tires and resulted in tire fragments impacting the fuselage.
- [NTSB WPR23LA128](https://openairdocs.org/ntsb/WPR23LA128), Mar 12, 2023: Jones Jay D Cassutt M 11 (N55XJ), Castroville, CA, substantial damage. Probable cause: A failure of the outboard trailing edge rib in the left wing, which resulted in a separation of the left aileron and 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 CEN15IA076](https://openairdocs.org/ntsb/CEN15IA076), Dec 10, 2014: Cessna 182S (N661SP), Springfield, IL, incident, minor damage. Probable cause: The improper installation of a doubler patch, which prevented the right flap from actuating and moving properly and led to the subsequent interference with the aileron.
- [NTSB ENG14IA016](https://openairdocs.org/ntsb/ENG14IA016), Feb 25, 2014: Douglas C 118A (N351CE), Emmonak, AK, incident, minor damage. Probable cause: The fatigue failure of the lower wing skin due to aging mechanisms. Contributing to the failure were lower wing skin inspection procedures insufficient to identify the crack.
- [NTSB WPR12TA445](https://openairdocs.org/ntsb/WPR12TA445), May 10, 2012: Beech C90 (N14CP), Boise, ID, substantial damage. Probable cause: Excessive loading on the left wing, which occurred over a period of time. Contributing to the accident was maintenance personnel’s failure to adequately inspect and document the left wing damage.
- [NTSB ERA12LA195](https://openairdocs.org/ntsb/ERA12LA195), Feb 25, 2012: Piper PA-36-300 (N59661), Americus, GA, substantial damage. Probable cause: The failure of maintenance personnel to properly secure a portion of the right wing leading edge, which resulted in the separation of the associated section of the leading edge during takeoff and the…
- [NTSB WPR11LA459](https://openairdocs.org/ntsb/WPR11LA459), Sep 19, 2011: Mcarthur Steen Skybolt (N77VW), Greenleaf, ID, substantial damage. Probable cause: Structural failure of the upper left wing during aerobatic flight.
- [NTSB WPR11FA225](https://openairdocs.org/ntsb/WPR11FA225), May 17, 2011: P&M Pegasus Quik 912S (N705PM), Hanalei, HI, substantial damage, 2 fatal. Probable cause: The pilot's continued operation of the aircraft with deteriorated wing fabric and his aggressive maneuvering at low altitude, which resulted in the right wing fabric’s failure during flight.…
- [NTSB WPR09CA182](https://openairdocs.org/ntsb/WPR09CA182), Apr 4, 2009: Cessna 172S (N4915F), Snohomish, WA, substantial damage. Probable cause: An in-flight collision with a crow.

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.
