## Newest cases

- [NTSB ERA21LA330](https://openairdocs.org/ntsb/ERA21LA330), Aug 15, 2021: Schweizer SGS 2-33A (N2805H), North Springfield, VT, substantial damage. Probable cause: The check pilot's failure to account for the extended departure distance from the airport during a simulated tow rope break and recovery.
- [NTSB GAA16CA479](https://openairdocs.org/ntsb/GAA16CA479), Sep 4, 2016: Schleicher ASW 27 (N27BZ), Benton, TN, substantial damage. Probable cause: The glider pilot's descent below the glidepath and the subsequent hard, off-airport landing.
- [NTSB WPR16LA096](https://openairdocs.org/ntsb/WPR16LA096), Apr 25, 2016: DG Flugzeugbau DG 800B (N800YG), Clements, CA, substantial damage. Probable cause: The motorglider pilot's decision to perform an in-flight engine start with insufficient altitude, which resulted in an off-airport landing and collision with trees after the engine did not start.…
- [NTSB WPR11CA023](https://openairdocs.org/ntsb/WPR11CA023), Oct 21, 2010: Air Tractor AT-802 (N4247U), Fort Hunter Liggett, CA, substantial damage. Probable cause: The pilot's misjudged glide path, which resulted in a runway undershoot and collision with terrain during landing.
- [NTSB CEN10CA167](https://openairdocs.org/ntsb/CEN10CA167), Mar 22, 2010: Cirrus Design SR22 (N616CP), Sugar Land, TX, substantial damage. Probable cause: The pilot's failure to maintain a proper glidepath and rate of descent during approach, resulting in a hard landing.
- [NTSB WPR09CA011](https://openairdocs.org/ntsb/WPR09CA011), Oct 12, 2008: Piper PA-38-112 (N2572N), Fresno, CA, substantial damage. Probable cause: The pilot's failure to maintain a proper glide path while on final approach.
- [NTSB DFW08LA217](https://openairdocs.org/ntsb/DFW08LA217), Aug 28, 2008: Cessna 172A (N6539B), Albuquerque, NM, substantial damage. Probable cause: The pilot's failure to maintain proper glide angle during the landing approach which resulted in a collision with a pole. Contributing to the accident were the pilot's lack of qualification,…

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.
