good summary of what they read on PPRune.
Now all we need is a complete investigation of this and other possible causes.
I seem to recall a China airline B737 that likely crashed after auto-throttle issues but the report was not made available by the time of the Tarom crash.
autothrottle malfunctions are low grade technical faults except with poorly trained crew so this latest accident has no cause yet in my mind until/unless all avenues are explored
