Hi Adam,
Stan will likely tell you the spar is really a non -issue anymore for resale, and there is a FSDO is the south somewhere that will extend the inspection to 5 years.
I have the contact in my files somewhere.
But if that 690B sells for that, I’ll be a bit surprised, but if it’s setup for fire flights and special radios, maybe that’s a unique buyer with deep pockets?
Relative to that dash 5–
A low time dash10T/Woodward/Fairchild/garmin-glass 690B would be worth more, which is hard to believe in the declining market environment.
