Default Cost to install a canopy?

The latter, quite definitely. Even in the highest-volume glider
"factory," craftsmen doing things onesey-twosey hold the central part
of the process. I think that none of the big players make more than a
few hundred units a year. That may sound like a lot, but it's a far cry
from the tens of thousands or hundreds of thousands of units you'd see
on a car or motorcycle production line.

The bottom line is that even in the factory environment manufacuring
glider parts is an expensive proposition. It may be less expensive than
field repairs and fabrication, but not by much, and business and
transportation expenses more than make up the difference.

Yes, it is definitely faster and more efficient to make a canopy and
frame assembly in the factory. They have the tools and processes and
procedures in place to do it correctly in the fewest possible hours.
However, with production rates so low, and with the installed base so
small, it simply does not make economic sense for them to dedicate part
of their production to spares manufacturing. For a lot of the parts,
they'd end up with a lot of expensive shelf space dedicated to
expensive spare parts for which there is no definite demand. That makes
sense when there are tens of thousands of units with an established
history of spares requirements. But with a few hundred units in the
field there simply is not enough data to build a realistic model of the
spares requirements.

Another problem is that, here in the US at least, the factory is a long
way away. That means expensive transatlantic shipping of a delicate
assembly.

Thanks, and best regards to all
