Recently I got a "Bleed Air Leak" annunciator on the right engine at about 6,000'. After reducing power about 80 degrees the light goes away and never comes on again, til the next flight. Mechancic inspects and says doesn't find anything. Anyone ever experience something like this and get a solution. I'm pressing for more inspection by the mechanic, but wondering if this has been experienced by some of you Westwind guys.
