Once up-and-running, at constant R.P.M., a compressor will never stall
You post limited knowledge pertaining only to engines that do not rely on VSV's for compressor MGT. I like the rolls bleed system, just that there are alot of other motors out there and I am also sure that (if it can happen it will)
It was not uncommon for new aircraft to suffer from Compressor Stall. This rules out Bogus parts theory.
Don't like the word "bogus", but substandard or failed are more common and easier for me to swollow, once again I revert back to the VSV engines, that damb cable on CF6's through the -50. If it was sticky on throttle advancement...BANG. Could theoreticly fail at power and Big BANG. Does not rule out anything.
