## Newest cases

- [NTSB WPR24LA205](https://openairdocs.org/ntsb/WPR24LA205), Jun 22, 2024: Replica PA-12 Replica (N406Z), Douglas, WY, substantial damage. Probable cause: A loss of power due to fuel exhaustion as a result of the pilot’s failure to calibrate the fuel flow indicator.
- [NTSB WPR23LA201](https://openairdocs.org/ntsb/WPR23LA201), May 24, 2023: Cessna 177B (N34713), Tucson, AZ, substantial damage. Probable cause: A partial loss of engine power due to restricted fuel flow resulting from foreign object debris in the fuel flow transducer.
- [NTSB WPR16FA176](https://openairdocs.org/ntsb/WPR16FA176), Sep 9, 2016: Cessna 310N (N126P), Wickenburg, AZ, substantial damage. Probable cause: Total loss of power to the right engine during takeoff due to a fuel contaminant, which blocked the fuel flow transducer and resulted in fuel starvation to the engine.
- [NTSB WPR14LA118](https://openairdocs.org/ntsb/WPR14LA118), Feb 23, 2014: Cessna P210N (N18DP), Bountiful, UT, substantial damage. Probable cause: Fuel starvation due to the in-flight loosening of the fuel lines attached to the fuel flow indicator as a result of inadequate maintenance.

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.
