I have managed to endure two seperate t/r failures over 27 years. Henceforth whenevere I am instucting or working as a training pilot the personel experience is great to utilize as a trainig tool. In Canada a lot of emphasis is put on t/r jams, loss of t/r authority and loss of t/r effectiveness. Any and all companies in any part of the world, and doing all types of work should positively be doing this also....Trust me, when (not if) this happens to you, you will be thankful if you had the training...
