Maybe. However, the factory service center that did the work said they
didn't know how to bid the job. Mooney was unable to locate any other
facility that had ever had to do this job before, so the shop had to
guess at the hours.
Apparently this hasn't happened before, at least not to Mooney's
knowledge.

Wow, kind of points to an inadvertant drawback of the "one-piece wing"
design. While arguably a stronger setup, sure makes this kind of issue
a much bigger deal than it would have been on a more typical GA
aircraft. $40K to repair some spar corrosion? Ouch!
