Probable cause: The pilot’s failure to maintain proper main rotor rpm during a low-level turn, which resulted in the main rotor rpm drooping, a loss of control at an altitude too low for recovery, and a subsequent…
- [NTSB CEN26LA144](https://openairdocs.org/ntsb/CEN26LA144), Mar 18, 2026: Mooney M20 (N1374W), Northlake, TX, substantial damage. Probable cause: The pilot’s inadequate fuel management which resulted in a total loss of engine power due to fuel starvation.

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.
