The glider is due for a 3000 hour inspection. Schleicher requires the control surfaces to be checked for mass balance as a part of the inspection program.

Regarding the monel question, did I just order the wrong rivets?

When in doubt, either drive to the airport to get the manual, or email
the factory and dealer for the correct info. RAS is a poor source for
approved data.

If it is a 3k inspection is that not per a factory S/B? if so it may
be on line.

In general drilling out a monel blind with a steel core is less fun
than Alum. YMMV
