Had a weirdly great day on the line thanks to a borrowed tool
We were chasing a phantom hydraulic leak on a King Air 200 for two days. My lead, who's been at the Anchorage hangar for 30 years, handed me his old-school stethoscope probe. Found the seep at a fitting behind the actuator in about 15 minutes. What's your go-to tool for finding those hard-to-spot leaks?
