## Newest cases

- [NTSB CEN26LA226](https://openairdocs.org/ntsb/CEN26LA226), Jun 14, 2026: Beech A36TC (N3701N), Kingsford, MI, substantial damage. Probable cause: The pin on the nose gear brace assembly that engages with the cam on the nose landing gear door actuator shaft was not seated inside the cam, which rendered the nose landing gear inoperative.
- [NTSB ERA26LA043](https://openairdocs.org/ntsb/ERA26LA043), Nov 14, 2025: Beech 95-B55 (N711FA), Dothan, AL, substantial damage. Probable cause: The failure of the left main landing gear actuator rods, which resulted in a gear up landing.
- [NTSB WPR11LA292](https://openairdocs.org/ntsb/WPR11LA292), Jun 21, 2011: Cessna 320F (N6160Q), Phoenix, AZ, substantial damage. Probable cause: The mechanic's failure to properly secure the nose landing gear actuator push-pull tube to the landing gear door hinge clevis, which resulted in the gear jamming and not fully retracting after…
- [NTSB DCA10IA021](https://openairdocs.org/ntsb/DCA10IA021), Jan 10, 2010: Airbus Industrie A319-131 (N816UA), Newark, NJ, incident, minor damage. Probable cause: A mechanical failure of internal components of the right main landing gear door actuator resulting in the flight crew being unable to fully extend the right main landing gear using the normal and…

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.
