Our club is looking into a new canopy for a Grob 103 Twin Astir. We received
an estimate from a well-known repair shop: $2,000 for the canopy and 50
hours of labor to install. I'm new to this field - I fly 'em, I don't fix
'em. But I'm having a hard time imagining what steps must be involved to
consume 50 hours. Hinge, latches... what am I missing?

First you have to remove the old plexy hopefully without any damage on
the original frame. Than probably fill the surface to provide smooth
contact. Glue the plexy to the frame. Cut it to fit and probably fill
and send before paint. Than you still have to sand and polish the new
surface. You shouldn't damage the new plexy during the whole procedure.
I don't say it's 50 hours, maybe more
