## Newest cases

- [NTSB ERA25LA235](https://openairdocs.org/ntsb/ERA25LA235), Jun 23, 2025: Cessna R182 (N262AL), Milton, FL, substantial damage. Probable cause: Separation of the throttle cable sleeve during takeoff, which resulted an uncommanded engine power reduction and the pilot’s inability to control the engine throttle, and resulted in a forced landing.
- [NTSB CEN25LA168](https://openairdocs.org/ntsb/CEN25LA168), May 4, 2025: Cessna 172N (N75775), Longmont, CO, substantial damage. Probable cause: The disconnected throttle control that resulted in a loss of engine power due to improper maintenance.
- [NTSB WPR25LA135](https://openairdocs.org/ntsb/WPR25LA135), Apr 8, 2025: Martin Uav Vbat (N443VA), Douglas, AZ, substantial damage. Probable cause: The malfunction of the throttle servo which resulted in the complete loss of engine power.
- [NTSB CEN25LA100](https://openairdocs.org/ntsb/CEN25LA100), Feb 17, 2025: Cessna 180 (N597JC), Breckenridge, TX, destroyed. Probable cause: The mechanic’s failure to properly install the throttle cable hardware resulting in a separation of the cable and loss of engine throttle control.
- [NTSB WPR25LA091](https://openairdocs.org/ntsb/WPR25LA091), Feb 9, 2025: Cessna 182N (N92467), Auburn, CA, substantial damage. Probable cause: The pilot’s improper use of throttle and brakes during engine start that resulted in a loss of control and impact with a hangar.
- [NTSB ERA24LA380](https://openairdocs.org/ntsb/ERA24LA380), Sep 14, 2024: Piper PA32 (N6FT), Baltimore, MD, substantial damage.

- [NTSB CEN23LA413](https://openairdocs.org/ntsb/CEN23LA413), Sep 20, 2023: Powrachute Airwolf (N820PP), Erie, CO, incident, substantial damage, 1 fatal. Probable cause: The pilot’s inadvertent manipulation of the throttle, which resulted in the aircraft traveling on the ground and the unsecured pilot being ejected from the aircraft and sustaining fatal injuries.
- [NTSB ERA23LA286](https://openairdocs.org/ntsb/ERA23LA286), Jul 4, 2023: Grumman American Avn. AA5A (N26387), Redstone Arsenal, AL, substantial damage. Probable cause: The separation of the clamp assembly securing the throttle control cable outer housing, which resulted in the pilot’s inability to control the throttle.

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.
