Are random system failures modeled?

There are a number of aircraft "wear" parameters in-game (See parameter list http://forum.1cpublishing.eu/showthr...338#post342338 ). I'm interested in:
(1) whether the game code for part failure if "wear" is gets too high is implimented.
(2) Presumably "wear" would not increase too much in a new plane on single mission, so I'm wondering if there is scope for introducing persistent aircraft states. ie. The same aircraft "wears" over a number of missions, until serviced.
(3) I've not experienced any spontaneous system failures (broken hoses/hydrolic lines, failed electrics etc). Has anyone else had any spontaneous sytem failures?
