Hello, has anyone here repaired a leak on the ballast tanks of a Jantar Standard 3 glider? I don't mean washing the tanks with paint but accessing the inside of the tanks to repair a leak.

I would like to know how the tanks are constructed. Are they separate tanks installed in the wings or do the spar and wing skins form the tank sides?

I am considering buying a Jantar with leaky ballast tanks and am trying to assess how big a job it is to make them water tight.

Hoping you can help.

regards

Andrew

Hi
I had a early Jantar and we received a TN for the water tank sealing.
We had to use a quantity of sealing liquid in each tank.
Rotate the tank a number of time, drain the liquid and let dry 24 hour.
We had to air pressurised the tank to a specific psi.
This value was to stay above a percentage of lost of pressure for a number of hours.
This is the procedure we had to use. I cannot be more precise because that
is 30 years ago.
