If the stabiliser jackscrew is such a prime suspect for this accident, as evidence by this thread, then why is it just sitting on the hangar floor with all the other wreckage? Surely, the NTSB would have been looking for it, retrieved it and sent it directly to the metallurgists for analysis? I can only assume it doesn't figure as highly in their minds as it does in the minds of PPruners? Or am I missing something?
