touch nothing, divert to the nearest airfield,

I've heard a statistic tossed around at Wings seminars stating that
most engine failures occur during a change or adjustment. Guest
engine experts seem to always agree not to touch anything if it's
still running and high confidence of the exact problem isn't
available.

I wish I could find the detailed information. Has anyone else heard
this?
