|Dominican Republic, February 6, 1996|
The cockpit voice recorder and flight data recorder were transported to the laboratories of the National Transportation Safety Board during the evening of February 28, 1996. An initial review of the recorders by the Safety Board and Dominican Republic civil aviation officials was conducted in the early morning hours of February 29, 1996. The read outs are continuing.
Both the CVR and FDR are providing quality data. There were discussions about airspeed indications early during the takeoff ground run and again after takeoff. While climbing through 7,300 feet, the sound of the stall warning stickshaker was heard. The airplane stopped climbing and started descending. The stickshaker sound continued for about 84 seconds until the end of the data. At the time the stickshaker activated, the recorded airspeed was about 335 knots. Data recorded from the ground based radar and other FDR data indicated a much lower airspeed.
Data are consistent with properly functioning flight controls, engines, and thrust reversers. Also, there is no indication of any unusual weather event or external forces acting on the aircraft.
The investigation is continuing with further study of the data and the possible recovery of additional components.
