I've been trying to finish up an instrument rating in my 69 Arrow. I had
the check ride scheduled for this afternoon so thought a short final
refresher with instructor yesterday would be a good idea.

First approach, lowered the gear for descent, oooops, right main indicator
still dark. Switch the bulbs, nope, same one. Flew by the tower, looked OK
to them. Took it back home, landed fine, into the shop.

The down indicator switch assembly is covered by a plastic housing, and the
plastic eventually gets old and brittle and when asked to flex too many
times eventually just broke the wire inside. So I'm going to replace the
entire assembly and do the one on the left side as well - did the nose gear
last year. It's a little nerve-wracking not knowing whether you're going to
get that let-down feeling on touchdown.

I'm concluding after a couple of years of ownership that buying an older
airplane gives you the opportunity to replace every moving part one at a
time.
