## Newest cases

- [NTSB CEN21LA187](https://openairdocs.org/ntsb/CEN21LA187), Apr 9, 2021: Eurocopter EC120 (N421PB), LeRoy, KS, substantial damage. Probable cause: The contamination of the fuel injection manifold filter due to improper maintenance, resulting in a partial loss of engine power during cruise flight. Contributing to the accident was the pilot’s…
- [NTSB CEN19LA331](https://openairdocs.org/ntsb/CEN19LA331), Sep 14, 2019: Cirrus SR20 (N200Z), Orange, TX, substantial damage. Probable cause: A total loss of engine power due to a fatigue failure of the fuel line from the fuel manifold to the No. 1 cylinder.
- [NTSB GAA16CA497](https://openairdocs.org/ntsb/GAA16CA497), Aug 22, 2016: Cirrus Design SR20 (N204AK), Brunswick, GA, substantial damage. Probable cause: The total loss of engine power during takeoff due to a loose B-nut on the fuel flow divider input fuel line fitting, which resulted in a fuel leak and fuel starvation.
- [NTSB ERA15FA016](https://openairdocs.org/ntsb/ERA15FA016), Oct 16, 2014: Rockwell International 112 (N1148J), Gainesville, GA, destroyed, 2 fatal. Probable cause: The partial loss of engine power due to the undetected blockage of the inlet and outlet ports of the manifold valve by an organic compound of an unknown source.
- [NTSB WPR14LA323](https://openairdocs.org/ntsb/WPR14LA323), Aug 1, 2014: Rans S-16 (N116GS), Fort Bridger, WY, substantial damage. Probable cause: The fuel flow divider inlet line’s B-nut coming loose during takeoff, resulting in a total loss of engine power. Contributing to the accident was the pilot's failure to adequately tighten the B-nut…

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.
