On our 914 powered XS, the exhaust pipe that comes thru the engine cowl gets
loose.
We once actually had it fall off, fortunately just prior to takeoff! We've
tried hi temp nuts, safety wiring the nut and made a longer nut from steel
rod which is safety wired, but still the pipe gets loose after a few hours.
Yesterday, we noticed an old Tech Talk article from Dec 2002 where Andy suggests
drilling thru the stub of the muffler and the tailpipe and inserting a self
tapping screw. Then you are to arrange the screw to be under the circular
clamp.
Has anyone done this and does it work?
