## Newest cases

- [NTSB CEN26LA215](https://openairdocs.org/ntsb/CEN26LA215), May 31, 2026: Eaa Acro Sport II (N23RA), Sheridan, AR, substantial damage. Probable cause: The pilot’s inadequate preflight inspection which resulted in a total loss of engine power due to fuel exhaustion.
- [NTSB CEN26LA210](https://openairdocs.org/ntsb/CEN26LA210), May 29, 2026: Cessna 172S (N386SP), Colorado Springs, CO, substantial damage. Probable cause: The student pilot’s failure to maintain directional control of the airplane during the takeoff, which resulted in a runway excursion and collision with runway signs.

Probable cause: The pilot's failure to retract the flaps during takeoff following a touch-and-go landing, which resulted in degraded climb performance and an impact with an object during an off-field landing.
- [NTSB CEN26LA053](https://openairdocs.org/ntsb/CEN26LA053), Nov 26, 2025: Piper PA-22-108 (N4588Z), Colorado Springs, CO, substantial damage. Probable cause: The pilot’s failure to maintain directional control during the landing.

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.
