1.12.12  Aircraft Attitude and Airspeed at the Time of Impact

The location of the debris field in relationship to the last primary radar return shows the aircraft was in a right turn prior to the time of impact. The debris field was relatively compact and supports a relatively steep water entry. The standby attitude display showed the aircraft to be at 20 degrees nose down and 110 degrees right bank at the time of impact. The dial face on the airspeed indicator had marks, made at the time of impact, that correspond to an airspeed of 300 knots. The structural damage indicates that the aircraft had a nose-down attitude of about 20 degrees, and a right bank in excess of 60 degrees. Analysis of the markings on various wreckage pieces indicated that the impact force was from 15 degrees right of the aircraft centreline.
