In the Board’s words — the closest cases
- CEN10LA3632010-06-28 · EMBRAER EMB-145LR · AMERICAN EAGLE AIRLINES INC
The inadvertent encounter with convective weather during cruise flight. Contributing to the accident was the flight crew's failure to detect and avoid the thunderstorm cell earlier in the flight, and the failure of air traffic controllers to provide the convective weather information to the flight crew.
- DCA12LA0912012-06-13 · BOEING 737-724 · UNITED AIR LINES INC
the flight crew's penetration of a rapidly developing thunderstorm cell in an area of forecasted convective activity. The serious injuries were the result of a misunderstanding between the captain and cabin crew regarding the potential for turbulence.
- CEN12LA1662012-02-19 · BOEING 737-832 · DELTA AIR LINES INC
An in-flight encounter with forecasted turbulence, which resulted in a serious injury to a flight attendant. Contributing to the accident was the flight attendant not being seated with her seatbelt fastened when the encounter occurred.
- DCA24FA1432024-04-03 · BOEING 737-7CT · SOUTHWEST AIRLINES CO
The pilot’s inadvertent encounter with convectively induced turbulence from a broken line of embedded thunderstorms moving across the region. Contributing to the accident was the failure of the air traffic controller to issue pertinent weather information along the airplane’s route of flight due, in part, to the sector over-saturation and frequency congestion caused by damaged communication equipment and the inability to split the sector to alleviate some of the traffic volume.
- DCA25LA1732025-03-27 · BOEING 787 · UNITED AIRLINES INC
An encounter with convective turbulence during cruise that was not detected in advance by cockpit weather radar or weather information services.

This is the pattern in the NTSB’s own record across similar accidents — which findings it cited, what it coded, what it recommended. It is drawn from the record, not written about this case, and it never assigns blame: investigations exist to prevent the next accident (ICAO Annex 13).
