## Newest cases

- [NTSB ENG25WA015](https://openairdocs.org/ntsb/ENG25WA015), Jan 20, 2025: Bombardier BD100 1A10 (CS-CHJ), Nassau, Bahamas, incident, no damage
- [NTSB CEN25FA006](https://openairdocs.org/ntsb/CEN25FA006), Oct 8, 2024: Beech C99 (N130GP), Norfolk, NE, destroyed, 1 fatal. Probable cause: The pilot’s failure to maintain adequate airspeed following a partial loss of engine power during takeoff, which resulted in a loss of airplane control. Contributing to the accident was the fatigue…
- [NTSB CEN23LA317](https://openairdocs.org/ntsb/CEN23LA317), Jul 22, 2023: Grumman G-164A (N9892), Patoka, IL, substantial damage. Probable cause: A partial loss of engine power due to the failure of two compressor turbine blades as a result of the engine operating near or above the engine’s operating limits for an undetermined amount of time…
- [NTSB WPR23LA278](https://openairdocs.org/ntsb/WPR23LA278), Jul 19, 2023: Aerospatiale AS-355E Twin Star (N102UM), Farmington, UT, substantial damage. Probable cause: The premature failure of one of the No. 2 engine compressor bleed valve, which resulted in a partial loss of power to that engine.
- [NTSB ENG23LA030](https://openairdocs.org/ntsb/ENG23LA030), Jun 17, 2023: Gulfstream Aerospace G-IV (N926TT), Sioux City, IA, incident, minor damage. Probable cause: A No. 2 (right) engine failure due to a spinner fairing separation and subsequent impact with the fan blades that resulted in a midspan fracture of one fan blade. The spinner fairing separated as a…
- [NTSB ENG22LA002](https://openairdocs.org/ntsb/ENG22LA002), Oct 2, 2021: Airbus A320-271N (N922NK), Atlantic City, NJ, incident, minor damage. Probable cause: The ingestion of a bird into the right engine during the takeoff roll caused a fan blade to fracture near the blade platform resulting in high fan blade off loads and engine vibrations sufficient to…
- [NTSB ERA21LA368](https://openairdocs.org/ntsb/ERA21LA368), Sep 17, 2021: Hughes 369 (N420AT), Ash, NC, substantial damage. Probable cause: A partial loss of engine power due to corrosion and erosion damage to the engine’s compressor section components.
- [NTSB ERA21LA287](https://openairdocs.org/ntsb/ERA21LA287), Jul 6, 2021: Piper PA46-500TP (N31062), Manteo, NC, substantial damage. Probable cause: The improperly secured pneumatic compressor discharge air (P3) line coupling nut on the engine, which ultimately allowed the nut to back off resulting in a partial loss of engine power.
- [NTSB DCA21FA085](https://openairdocs.org/ntsb/DCA21FA085), Feb 20, 2021: Boeing 777-222 (N772UA), Broomfield, CO, incident, minor damage. Probable cause: The fatigue failure of the right engine fan blade. Contributing to the fan blade failure was the inadequate inspection of the blades, which failed to identify low-level indications of cracking, and…
- [NTSB ERA21FA130](https://openairdocs.org/ntsb/ERA21FA130), Feb 15, 2021: Bell 206 (N13AT), St Thomas, CB, destroyed, 4 fatal. Probable cause: A total loss of engine power due to fatigue failure of two of the stage 3 compressor blades. Contributing to the failure of the compressor blades was the failure of maintenance personnel to inspect…

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.
