Since the horror stories surrounding AP nazis seem to continut surface, thought I might post a recent Mike Busch article of a similar vein.  http://www.avweb.com/news/savvyaviator/savvy_aviator_54_is_repair_a_lost_art_197316-1.html

Encounter one of the many "I won't sign it off unless I replace"?  Have a read.
