Photo  Apex Departing Slot clearly shows where the missing piece of the
apex

seal bent over the straight edge of its slot when it departed. Apparently

when it left the clearance was getting less and the departing edge was

apparently caught between the lip of the slot and the rotor housing forming

a flatten corner.



Ed,

How well does the position of the break line up with your exhaust port?  Are
there any tiny chips near the break that look like they may have been around
a while?  I'm thinking of the possibility of a piece of debris chipping the seal in
the vicinity of where it flexes as it crosses over the exhaust hole.  Stress
riser, being the unpredicable ^%&# they are, will always give out just as
you cross the limit of not being able to glide home.
