I feel your pain @CharlieD3. I called on a Six a couple weeks ago. He told me useful was 1483. Awesome, I'll be down to look at it tomorrow. Got there and find the newest w&b in the poh was from 2000, and was for installing avionics that had since been replaced. That one showed 1320 useful. Never mind the fact that the plane isn't airworthy.... that's a long damn way from the number he gave me, and well short of what I'm looking for. They said they had never actually done a w&b, so they didn't notice it wasn't up to date.... I think a shockingly low percentage of pilots even bother, which is why it shows up so infrequently in ads and so frequently in NTSB reports.
