You're right Carl, I did mean to say ribs. Sorry for the confusion.
I contacted Free Flight Systems in Waco TX tobay to see what their position was on the Terra Avionics since they were the ones who bought out Terra. They said they now service and plan to continue to service all the late model digital Terra Avionics as found in this plane. They informed me they have new, still in the box, the digital Terra 760D(760 Com channels like found in this plane-it has two of them), that can't be sold as new but must now be sold as refurbished, for $950 exchange or $1,350 without.
However, Terra is still out of business. Regardless of the fact that the radios may now work fine, there is no assurance of how long this company will continue to support this now defunct company's product. Due to this fact, and the fact that the brand name is now out of business, I feel the avionics must be discounted even though this is an IFR certified plane.
The undisclosed damage history is still my biggest problem. I feel that the planes repairs probably have withstood the test of time. Unfortunatly though, damage history is still damage history and will follow this plane around now forever more and subsequently be reflected in it's market value.
Best to deal with this damage history now and attempt to renegotiated a lower price up front that reflects this, as it could never be overcome later when I attempted to sell it.
Thanks for all the input. I will wait to see what the FAA CD says and then possibly attempt to renegoiate the price depending upon if the repairs have been properly documented. If they have not, I will ask for my money back and walk. I don't want to get further tangled up in a mess like that.
