GTT-shirt,
wasn't suggesting RB system is unreliable - in-fact I agree that I've only seen perhaps 1 headscratching defect a year and the local airline has 500 engines on-wing. But, the point I wanted to make was the peculiarity of some of the final fixes. Especially now with causes including FADEC technology, C-duct heatsheld material interference and even one event on a CFM where the Arinc 429 data wire in the pylon actually caused an EGT signal fluctuation.....
