## Newest cases

- [NTSB CEN17LA121](https://openairdocs.org/ntsb/CEN17LA121), Feb 14, 2017: Beech C90A (N1551C), Rattan, OK, substantial damage. Probable cause: The loss of electrical power due to the pilot’s inadvertent selection of the engine start switches and the subsequent fuel exhaustion to the left engine as the pilot attempted to locate visual…
- [NTSB WPR16FA055](https://openairdocs.org/ntsb/WPR16FA055), Jan 18, 2016: Airbus EC130 (N11VQ), Hanalei, HI, substantial damage. Probable cause: The fatigue failure of the engine fuel pipe as a result of vibration caused by a worn starter-generator front bearing support, which excited the fuel pipe and caused it to oscillate at a resonant…
- [NTSB WPR15LA165](https://openairdocs.org/ntsb/WPR15LA165), May 16, 2015: Raytheon B200 (N505SP), Carlsbad, CA, substantial damage. Probable cause: The pilot’s inadvertently turning on the starter switches, which turned off the generators and resulted in a loss of electrical power and gear-up landing. Contributing to the accident was the pilot’s…
- [NTSB ERA10LA325](https://openairdocs.org/ntsb/ERA10LA325), Jun 18, 2010: Schleicher ASH26 (N26EL), Shelbyville, TN, substantial damage. Probable cause: A complete loss of electrical and engine power over unsuitable terrain due to a cannon plug that became disconnected for undetermined reasons.

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.
