Jet engines used to be stripped down and "CLA'd" at regular intervals, but as they become more reliable, the point was reached where assembly errors in post-stripdown rebuilds became a significant cause of subsequent problems. So today's engines are left on the wing for as long as they keep "turning and burning". +++++++++++++ Dear Doug, It's true that modern jet engines are not disassembled for inspection as = frequently as in the past, but engine condition and performance is = monitored very closely and provides the needed info to provide for = on-going assessment of engine conditon. Our cameras lack this type of = instrumentation and my thus benefit from regular CLA's. I should add = that I am not consistent. So far as I know, my M3 has never been opened. = It's probably about time.
