## Newest cases

- [NTSB WPR17LA216](https://openairdocs.org/ntsb/WPR17LA216), Sep 25, 2017: Cessna 172P (N5448K), Tamuning, substantial damage. Probable cause: The pilot's inadequate preflight inspection, which resulted in oil exhaustion and a subsequent total loss of engine power during cruise flight.
- [NTSB CEN17FA167](https://openairdocs.org/ntsb/CEN17FA167), Apr 25, 2017: Cessna 421C (N421TK), Huntsville, TX, destroyed, 1 fatal. Probable cause: The pilot's failure to identify the alternate runway, to perform a timely precautionary landing, and to maintain airplane control. Contributing to the accident was the failure of the left engine due…
- [NTSB CEN12LA455](https://openairdocs.org/ntsb/CEN12LA455), Jul 17, 2012: Cessna 175A (N7003E), Shelby, IL, substantial damage. Probable cause: The loss of engine power due to oil starvation for reasons that could not be determined because engine examinations revealed no malfunctions or failures that would have led to oil starvation.
- [NTSB ERA10LA335](https://openairdocs.org/ntsb/ERA10LA335), Jun 25, 2010: Cessna 210D (N3973Y), Babylon, NY, substantial damage. Probable cause: The loss of engine power due to the failure of the oil filter gasket and the subsequent engine oil depletion.
- [NTSB ERA09CA430](https://openairdocs.org/ntsb/ERA09CA430), Jul 30, 2009: Cessna 172N (N733BS), Manassas, VA, substantial damage. Probable cause: The student pilot’s failure to maintain directional control during takeoff.

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.
