Beware! The new design of clamp for securing the muffler heat shield
(which uses screwed fasteners instead of a crimped fasteners) has no
thread locking and shakes itself loose due to engine vibration. In my
case one of the two clamps fell right off after 8 hours flying and the
other one was very loose - not nice if the remains of the clamp find
their way back to snag the rudder cables. Also not nice if the heat
shield falls off and the muffler cooks something which shouldn't be
cooked. I will try lock nuts next time.
Happy landings!
