I’m really hopeful this is an easy fix.  New owner of 98 Ovation.  Something that we didn’t catch in the pre-buy was that the armrest stop doesn’t seem to work, so the armrest just freewheels/falls down.  I don’t yet have a maintenance manual and sorry, forgot to take pictures while at the hangar yesterday.  If needed, I will take pics next weekend. Hopefully others are familiar with the issue and can make a recommendation to try.
