Hi everybody!
I just had a conversation with some friends yesterday about the vertical stabilizer trim of the 737's.
We compared the accident of the MD-80 Alaskan Airlines, with the Silkair 185, 737 (although its not sure that it was vertical stabilizer failure in the silkair flight).
There is a video in the internet that shows how the trim works in the 737, im sure that youll know it here. Aircraft trim system | Veoh Video Network (http://www.veoh.com/videos/v382244KFJh32DJ)
Infos about the 737 trim scematic that we found is here.

Now the question comes..!
How about if a vertical stabilizer trim fails (disconnects from the jackscrew) in the 737 just as in the MD80 Alaskan airlines??
I know that is more difficult due to the location of the trim stabilizer, but what IF ?
Is there any backup mechanism that you can maintain pitch control of the 737 aircraft ?
Thanx Guys
