In the Board’s words — the closest cases
- ERA09LA3962009-07-10 · AIRBUS A320-232 · JETBLUE AIRWAYS CORP
An inadvertent in-flight encounter with turbulence during approach. Contributing to the accident was the passengers' failure to follow the instructions of the illuminated seatbelt sign.
- 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.
- DCA12FA0462012-02-24 · AIRBUS A321 · U.S Airways Inc.,
an encounter with convective turbulence that resulted in injury to a passenger who was not seated when the seatbelt sign was illuminated.
- DCA16CA2022016-06-12 · AIRBUS A321 231 · American Airlines
an encounter with convective turbulence that resulted in a flight attendant injury.
- 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.
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).
