Clandestino. BEA report the a/c did not begin to climb until the Pitch was 10 degrees+.
In descent, robust enough to keep the altitude from increasing with 9 degrees PITCH UP, a/c don't climb whilst arresting descent.
They reduce ROD instead, until the rate becomes positive, as per BEA.
WINDSHEAR event on ACARS. TCAS event on ACARS. Repeated descent commands of 5000fpm by the autopilot.
BEA have vacuumed the time period prior to the loss of Autopilot.
Odd. "Baby AUTOPILOT kills all!" ?
