## Newest cases

- [NTSB ERA25LA157](https://openairdocs.org/ntsb/ERA25LA157), Feb 25, 2025: Beech E33 (N7697N), Lenoir, NC, substantial damage. Probable cause: The mechanic’s inadequate annual inspection of the airplane and failure to comply with an applicable airworthiness directive, which resulted in a total loss of engine power due to oil starvation.
- [NTSB CEN24LA211](https://openairdocs.org/ntsb/CEN24LA211), May 22, 2024: Cessna 172RG (N751DW), Chandeleur Island, LA, substantial damage. Probable cause: A fatigue failure of the engine oil pressure line, which resulted in the loss of engine oil during the flight and subsequent damage to the nose landing gear support structure during the precautionary…
- [NTSB ERA22LA011](https://openairdocs.org/ntsb/ERA22LA011), Oct 10, 2021: Flight Design Ctls (N121YT), Greenville, SC, substantial damage. Probable cause: A total loss of engine power resulting from the in-flight disconnection of oil hoses from the oil thermostat.

- [NTSB WPR14LA207](https://openairdocs.org/ntsb/WPR14LA207), May 24, 2014: Cessna 182 (N97038), Arvin, CA, substantial damage. Probable cause: The pilot’s failure to reconnect the air-oil separator return line after completing an oil change, which resulted in a total loss of engine power due to oil starvation.
- [NTSB WPR13LA085](https://openairdocs.org/ntsb/WPR13LA085), Jan 5, 2013: Jeremiah Jackson Vans RV-10 (N262NJ), Julian, CA, substantial damage. Probable cause: A loss of engine power due to oil starvation as a result of a disconnected oil line. Contributing to the accident was an insufficiently tightened oil line fitting.
- [NTSB CEN12LA508](https://openairdocs.org/ntsb/CEN12LA508), Jul 10, 2012: Cessna 172M (N12504), South Wayne, WI, substantial damage. Probable cause: Internal engine component failures, which resulted from oil starvation due to debris in the oil system.

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.
