## Newest cases

- [NTSB CEN19LA159](https://openairdocs.org/ntsb/CEN19LA159), May 30, 2019: Lancair LC41 (N2514F), Cleburne, TX, substantial damage. Probable cause: A total loss of engine power due to oil starvation as the result of the oil pressure switch failure due to a manufacturing defect.
- [NTSB WPR18LA050](https://openairdocs.org/ntsb/WPR18LA050), Dec 17, 2017: Gray Jim Robert Exec (N716JB), Caldwell, ID, substantial damage. Probable cause: Failure of the oil pressure gauge line, which resulted in oil exhaustion and a total loss of engine power.
- [NTSB WPR15LA085](https://openairdocs.org/ntsb/WPR15LA085), Jan 16, 2015: Cubcrafters CC11-160 (N232LT), San Luis Obispo, CA, substantial damage. Probable cause: The pilot's inadequate instrument scan during cruise flight, which resulted in his failure to notice a loss of engine oil pressure. Contributing to the accident was the failure of the oil pressure…

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.
