On Aug 8th 2012 the NTSB released their brief factual report stating the aircraft encountered clear air turbulence at FL180 on departure from Pago Pago resulting in four jolts of moderate intensity. The aircraft was in clear skies with thunderstorms around the area. The fasten seat belt sign had been illuminated, the passengers were in their seats and the flight attendants preparing beverage service. Two flight attendants working the aft cabin received injuries, one serious, the other minor injuries.
The flight data recorder showed vertical accelerations increasing to +1.59G in two seconds, then reducing to +0.66G within the next two seconds, increasing again to the maximum of 1.75G and dropping to 0.05G within the next 2 seconds. The disturbance lasted for less than 10 seconds associated with a change in wind speed and direction.
