Chippendale Report p82;
"Eight seconds prior to impact and two seconds before the GPWS warning sounded, the roll mode FMA changed from 'NAV track' to 'Heading Select' as the 'Heading Select' knob was pulled out . This would be done to turn the aircraft through the auto-pilot and followed a discussion by the pilots which way to turn to get out of their present position. The co-pilot said 'it's clear to turn to the right' but the Captain contradicted him. Immediately the heading select knob was pulled out the aircraft commenced to roll to the right. The right roll which was also evidenced by movement of ailerons and spoilers which reached a maximum of 11 degrees bank 3.5 seconds before impact. The roll was then reversed, as the pilot attempted to commence a left turn."
