"we have an air leak at the piston valve (photo attached). I tightened that screw as much as possible, but the air is still leaking slightly. We also have air leaks at two TT valves (photo attached). One coil is disconnected, and we also have a leak at that valve. In the tunnel under the crew corridor, the valve is leaking air, as are several quick connectors. There is no valve to close the air supply at that location, so one needs to be installed."
