## Newest cases

- [NTSB ANC22FA041](https://openairdocs.org/ntsb/ANC22FA041), Jun 9, 2022: Bell 407 (N402SH), Kalea, HI, substantial damage. Probable cause: The in-flight separation of the tail boom as a result of abnormal loading and fracture of the upper-left tail boom attachment bolt due to a gap between the upper-left longeron and aft fuselage…
- [NTSB WPR21LA037](https://openairdocs.org/ntsb/WPR21LA037), Nov 4, 2020: Remos Aircraft Gmbh Flugzeugbau GX (N87GX), Glendale, AZ, substantial damage. Probable cause: The material overstress failure of the airframe’s aluminum carry-through of the main landing gear.
- [NTSB WPR13FA411](https://openairdocs.org/ntsb/WPR13FA411), Sep 16, 2013: Bell UH 1B (N204UH), Detroit, OR, substantial damage, 1 fatal. Probable cause: The fatigue failure of the upper two tailboom attachment points, which resulted in the tailboom separating from the fuselage during logging operations. Contributing to the accident was poor…
- [NTSB CEN10LA560](https://openairdocs.org/ntsb/CEN10LA560), Sep 20, 2010: Schweizer 269C (N34LB), Schaumburg, IL, substantial damage. Probable cause: The in-flight separation of the left aft cluster fitting assembly following the loss of torque on the lock nut due to a manufacturing defect.
- [NTSB CEN10LA414](https://openairdocs.org/ntsb/CEN10LA414), Jul 14, 2010: Wogenstahl Wallace L Wogenstahl 281 MR (N5281R), Mount Cory, OH, substantial damage. Probable cause: The improper installation of the rivets at the aft fuselage bulkhead which resulted in the pilot not having full elevator control on 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.
