Incident Overview
According to the pilot, the flight encountered moderate turbulence while climbing through 13,500 feet, resulting in a serious injury to a flight attendant. The seat belt sign had been turned off when the aircraft passed 10,000 feet.
Crew Observations and Actions
Before the turbulence encounter, the flight crew observed convective buildups on radar approximately five miles northeast of their position. However, no avoidance maneuver was initiated until after the aircraft had already entered the turbulent air.
Additional Details
The incident occurred during the climb phase of the flight. At 10,000 feet, the flight crew deactivated the seat belt sign. Subsequently, while climbing through 13,500 feet, the aircraft experienced moderate turbulence. This turbulence caused a serious injury to one of the flight attendants on board. The flight crew had been aware of potential convective activity, as they had spotted buildups on the radar display five miles to the northeast of the aircraft's location. Despite this awareness, the crew did not take any action to avoid the turbulent area until after the turbulence was already encountered. No other details regarding the flight or the extent of the injury were provided in the report.
