NTSB narrative
On May 16, 2011, at about 1830 eastern daylight time, Pinnacle Airlines flight 3621, a DHC-8-402, N351NG, encountered severe turbulence while descending through about 14,000 feet while on initial approach to Ronald Regan National Airport (KDCA), Washington, District of Columbia. One flight attendant received a serious injury and the airplane was not damaged. The flight was operating under 14 CFR Part 121 as a regularly scheduled passenger flight from Newark International Airport (KEWR), Newark, New Jersey to KDCA.
According to the operator, the flight crew had not received any PIREPS or NOTAMS of forecasted turbulence and the flight attendants (FAs) had just stowed the galley service carts when the turbulence was encountered. One FA was thrown to the floor injuring her foot. The flight attendant was assisted to a passenger seat where ice was administered to her swollen foot.
Paramedics met the flight upon landing and transported the injured flight attendant to the hospital where she was diagnosed with a fracture in her right foot.
Probable cause
an inadvertent encounter with clear air turbulence.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, damage. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
