## Newest cases

- [NTSB ERA25LA198](https://openairdocs.org/ntsb/ERA25LA198), May 7, 2025: Diamond Aircraft Ind DA 40 NG (N499BW), Sanford, NC, substantial damage. Probable cause: The mechanic’s re-use of worm drive clamps, which resulted in a separation of the turbocharger air discharge duct and a partial loss of engine power during initial climb.
- [NTSB ERA25LA051](https://openairdocs.org/ntsb/ERA25LA051), Nov 18, 2024: James A Gray Just Aircraft Highlander (N102XP), Fountain Inn, SC, substantial damage. Probable cause: A total loss of engine power for undetermined reasons.
- [NTSB WPR24LA267](https://openairdocs.org/ntsb/WPR24LA267), Aug 4, 2024: Piper PA-28R-201T (N135DG), Sacramento, CA, substantial damage. Probable cause: A loss of engine power during the initial climb due to the detachment of the turbocharger’s inlet sleeve as a result of the installation of an incorrect sleeve clamp.
- [NTSB WPR17IA198](https://openairdocs.org/ntsb/WPR17IA198), Aug 22, 2017: Enstrom F 28F (N52PD), Glendale, AZ, incident, no damage. Probable cause: An internal failure of the turbo-compressor, which resulted in oil leaking into the turbo-compressor’s exhaust.
- [NTSB CEN12LA558](https://openairdocs.org/ntsb/CEN12LA558), Aug 17, 2012: Beech A36 (N262EA), Ruleton, KS, substantial damage. Probable cause: The improper installation of the wastegate controller O-ring, which resulted in a partial loss of engine power.
- [NTSB CEN11LA327](https://openairdocs.org/ntsb/CEN11LA327), May 8, 2011: Piper PA 46-350P (N80JB), Chico, TX, substantial damage. Probable cause: The mechanic's improper installation of the turbocharger's exhaust balance system, which resulted in an in-flight fire.

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.
