Artificial Horizon overhaul service includes complete disassembly, cleaning and inspection of all component parts. TGH will contact you and advise you of the condition of your Vacuum Attitude Indicator and the exact costs of repair immediately after the initial inspection of the indicator.

TGH provides a one year limited warranty on all Vacuum Attitude Indicator

overhauls.
