I too thought the article was great, however I was interested as to why the US court still found fault with Parker Hannifins rudder PCU?
Watching that cornerstone of aviation fact, Air crash Investigation (note sarcasm), the program postulates that other factors were responsible citing evidence such as similarities between SA 185 and UA 585 rudder hard over, the fact that the FDR had been switching itself off in the preceding flights etc.
I could be wrong but I believe the LA court case with Parker Hannifin is in appeal.
