Hi . In our Jantar Standard ( 1977) plastic pipe for TEC probe inside vertical stabilizator is LEAKED . Is any solution to seal it ( for sample any liquid glue ) without opening stabilizator . Thanks .
Unfortunately, with plastic tubing that old, there is no point in heroics to try to plug one leak. The tubing is most likely old and rotten, and if you plug one leak, there will be another in some other spot in a few weeks or months. You are probably better off replacing the tubing. A Jantar service expert can probably do it with a minimum of hole-cutting.

Is there no way to pull through replacement tubing using the old one as the initial lead?
Don't know specifically on the Jantar, but I did this on a Standard Cirrus. Used the old tube to pull tough nylon string, then used the string to pull the new tubing. I didn't trust the old tubing to pull the new tubing.

That said, if the old tubing has fastening points along its run, obviously those will have to be dealt with first before anything can be pulled by the old tubing. And if there are tight bends to be negotiated, well, you know how that will go.
