## Newest cases

- [NTSB ERA19LA032](https://openairdocs.org/ntsb/ERA19LA032), Oct 27, 2018: Titan T51 (N154DF), Valkaria, FL, substantial damage. Probable cause: The partial, then total, loss of engine power due to detonation and associated damage to several pistons as a result of an overly lean fuel-to-air ratio.
- [NTSB ANC17LA008](https://openairdocs.org/ntsb/ANC17LA008), Nov 25, 2016: Airborne Extreme SQ-12 (N37PX), Palmer, AK, substantial damage. Probable cause: The fuel injector manufacturer's inappropriate guidance to use a 5-ampere circuit breaker in place of the required 10-ampere circuit breaker on the fuel injector circuit, which resulted in the…
- [NTSB ERA13LA405](https://openairdocs.org/ntsb/ERA13LA405), Sep 6, 2013: Crowder Michael H Sonex (N293SX), Waxhaw, NC, substantial damage. Probable cause: The pilot/owner/builder’s improper routing of the engine’s crankshaft position sensor cable next to the engine’s exhaust system, which resulted in a total loss of engine power in flight.
- [NTSB ERA13TA261](https://openairdocs.org/ntsb/ERA13TA261), May 31, 2013: Bell 407 (N407HC), Columbia, MD, substantial damage. Probable cause: The short circuit failure of a tantalum capacitor, internal to the engine’s electronic control unit, resulting in an uncommanded shutdown of the engine in flight.
- [NTSB ENG11IA016](https://openairdocs.org/ntsb/ENG11IA016), Feb 9, 2011: Boeing 757-2Q8 (N704X), Minneapolis, MN, incident, minor damage. Probable cause: the failure of the right engine's fuel control unit to operate correctly when the fuel metering valve became frozen in the full open position because of corrosion on the fuel metering valve slide and…
- [NTSB CHI08IA152](https://openairdocs.org/ntsb/CHI08IA152), Jun 5, 2008: Eclipse EA500 (N612KB), Chicago, IL, incident, no damage. Probable cause: The airplane manufacturer's inadequate software design requirements of the engine's full authority digital electronic controls (FADEC) fault logic that resulted in a simultaneous unrecoverable loss…

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.
