SB from Cessna expiring

[JeffAxel]

I think the SB you are referring to is the one to install supplmentary seat stops, basically an inertia reel on the seat frame with the fixed end of the belt on the floor. The pilot's seat was on Cessna, you had to pay for the co-pilot seat. Still a good deal in my opinion. I don't recall the SB number off hand, but you might check with CPA if someone here doesn't come up with it. Your mechanic might know as well.
