## Newest cases

- [NTSB ERA24LA330](https://openairdocs.org/ntsb/ERA24LA330), Jul 29, 2024: Raytheon A36 (N934PC), Naples, FL, substantial damage. Probable cause: Contamination of the airplane’s fuel system with debris, which resulted in restricted fuel flow through multiple fuel injectors and the subsequent partial loss of engine power.
- [NTSB ERA24LA066](https://openairdocs.org/ntsb/ERA24LA066), Dec 15, 2023: Diamond Aircraft Ind DA 40 NG (N907L), Asheville, NC, substantial damage. Probable cause: Fatigue failure of the No. 4 inner main bearing cap screw and connecting rod bolts, which resulted in a total loss of engine power. Contributing to the failure were the low material strength of the…
- [NTSB CEN23FA314](https://openairdocs.org/ntsb/CEN23FA314), Jul 20, 2023: Piper PA-31P (N200RA), Kearney, MO, destroyed, 1 fatal. Probable cause: The pilot’s decision to operate an airplane with known fuel leaks, his failure to conduct an engine run-up before takeoff, his subsequent failure to abort the takeoff, and the mechanic’s inadequate…

- [NTSB CEN17LA251](https://openairdocs.org/ntsb/CEN17LA251), Jul 2, 2017: Cody Hawkins JA30 Superstol (N2463H), Ponca City, OK, substantial damage. Probable cause: Contamination of the fuel system, resulting in a partial loss of engine power and subsequent off-airport 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.
