Thai Smile flight WE050, an Airbus A320-200, was flying at FL270, speed 240 knots above Sung Noen District, Nakhon
Ratchasima Province when it flew into turbulence, causing a flight attendant to fall on the kitchen floor near Exit 2R, suffering pain in her back and being unable to get up by herself.
While flying at FL270, 109 nautical miles Northeast of Suvarnabhumi Airport. The pilot deviated to the left of a cloud formation and using visual and radar to determine that the weather was clear. Afterwards, the aircraft began to vibrate violently, so the pilot decreased speed from 270 to 240 knots and activated the seatbelt sign. At the time, the flight attendants were serving beverages to passengers. The inflight manager returned to seat 1L and announced to the passengers to take their seats and fasten their seatbelts until the seatbelt sign was switched off and the 2 crew members in the middle of the cabin returned to their seats 2L and 2R, which were located at the rear of the aircraft. When the 2R flight attendant returned to her position, she found that another flight attendant had not yet taken her seat because there was still a 1R flight attendant in the Aft Galley assisting with the storage of items. Meanwhile, the aircraft was vibrating violently. She fell on the floor near exit 2R and was unable to get up on her own. As a result, the flight attendant reported to the inflight manager, who then informed the pilot that one of the flight attendants had suffered back injury.
Causes
This accident occurred because the aircraft entered turbulent conditions while flying at FL270. The aircraft vibrated violently. This caused a flight attendant on duty to fall down on the floor, resulting in serious injury.
