The NTSB's narrative final · quoted from the NTSB record

United Airlines flight 854, operating between George Bush Intercontinental / Houston Airport (IAH), Houston, Texas, and Jorge Chávez International Airport (LIM), Lima, Peru, encountered moderate turbulence while in cruise. One flight attendant sustained a serious injury during the turbulence encounter. The captain served as the flying pilot and the first officer as the pilot monitoring for the entire flight. Prior to the flight, the crew reviewed the dispatch release and weather forecasts, which indicated areas of light to moderate turbulence along the route, and no other significant turbulence risks were identified along their route.

However, turbulence began before they could fully stow the carts, leaving them only able to park the carts in the galley without securing them back into their slots. While one flight attendant stated that while they were attempting to prevent a cart from tipping over, the airplane experienced a “big shake”. The flight attendant was thrown to the floor, striking her back against the edge of a jumpseat before falling to the floor. The flight attendant was able to secure themselves in a jumpseat for the remainder of the turbulence encounter. Following the turbulence, the captain made a “fli
