## Newest cases

- [NTSB CEN17LA305](https://openairdocs.org/ntsb/CEN17LA305), Aug 5, 2017: Burkhart Grob Flugzeugbau G102 Club Astir Iiib (N102BK), Marion, OH, substantial damage. Probable cause: The pilot’s failure to follow the before takeoff checklist, which resulted in an improper takeoff configuration and subsequent uncontrolled descent into terrain during a departure climb.
- [NTSB ERA14CA126](https://openairdocs.org/ntsb/ERA14CA126), Feb 18, 2014: Schempp-Hirth Ventus 2B (N411SD), Burnsville, NC, substantial damage. Probable cause: The pilot's improper use of the spoilers, which resulted in an uncontrolled descent and subsequent impact with trees.
- [NTSB CEN12CA548](https://openairdocs.org/ntsb/CEN12CA548), Aug 10, 2012: Schleicher ASW22 (OK-2227), Uvalde, TX, substantial damage. Probable cause: The pilot did not fully stow the glider’s airbrakes, which prevented the glider from obtaining adequate airspeed during the takeoff roll.
- [NTSB WPR12CA288](https://openairdocs.org/ntsb/WPR12CA288), Jun 24, 2012: Dg-Flugzeugbau DG-500MB (N505JL), Richland, WA, substantial damage. Probable cause: The failure of the spoilers to retract because the right wing spoiler’s lower plate became jammed, which resulted in the glider not having enough lift to make it to the runway surface.
- [NTSB ERA12LA401](https://openairdocs.org/ntsb/ERA12LA401), Jun 18, 2012: Beech 400A (N826JH), Atlanta, GA, substantial damage. Probable cause: The flight crew's failure to obtain the proper airspeed for landing, which resulted in the airplane touching down too fast with inadequate runway remaining to stop and a subsequent runway overrun.…
- [NTSB ERA11FA401](https://openairdocs.org/ntsb/ERA11FA401), Jul 15, 2011: Slingsby Capstan Type 49B (N7475), Hollywood, MD, substantial damage, 1 fatal. Probable cause: The glider pilot’s improper response to the “check spoilers” signal from the tow pilot. Contributing to the accident was the glider pilot’s failure to confirm that the spoilers were closed and locked…
- [NTSB ERA11LA025](https://openairdocs.org/ntsb/ERA11LA025), Oct 18, 2010: Schempp-Hirth Ventus B/16.6 (N188PX), Warren, VT, substantial damage. Probable cause: The pilot's inadvertent deployment of the airbrake handle past the upper limit of its normal operating range, which resulted in binding of the controls.
- [NTSB WPR10CA015](https://openairdocs.org/ntsb/WPR10CA015), Oct 11, 2009: Let Blanik L-13 (N948LC), Llano, CA, substantial damage. Probable cause: The student pilot's improper use of the airbrakes while on approach for landing.

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.
