Shows what I do NOT know! I was assuming a new canopy would include the
frame, hinge, latch etc. so it could be installed as a unit. I haven't been
out to look at the Grob since this issue came up, but I seem to remember it
as a fairly simple structure. I'm wondering whether Grob sells a new
canopy-frame-hinge-latch combo for less. Factory labor to assemble new
things in an repetitive process is usually less expensive than a craftsman
in the field repairing a similar unit... whether it's a television, a car
engine, or whatever, major repair is usually more expensive than replacement
with a factory-assembled unit. But maybe such assemblies are not available
from Grob, or maybe the typical economics don't hold true in this market.

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
