- DCA19CA1512019-05-25 · BOEING 737-8H4 · Southwest Airlines Co
an encounter with convectively induced turbulence while penetrating cumulus clouds during descent.
- DCA09IA0712009-08-03 · BOEING 767-224 · CONTINENTAL AIRLINES INC
The flight crew's inadvertent flight through the top of a convective updraft that resulted in an encounter with convective induced turbulence. Contributing to the severity of the incident was the unrestrained status of several passengers, contrary to the lighted seat belt sign.
- DCA10FA0122009-11-19 · BOEING 777-200 · United Airlines Inc.,
The flight crew’s inadvertent encounter with a small area of cumulous clouds at night that resulted in moderate to severe convectively induced turbulence.
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).
