Amelia Posted March 25 Report Posted March 25 Asking for a friend. No, really! My esteemed mechanic is needing information about a Brittain vacuum-controlled wing-leveler for a customer’s 1966 M20c. He says there’s no vacuum going to the servos. Vacuum is good. Must be a controller someplace, but it’s not listed in the parts book. He’s looking for a schematic, or some information on where he might look. It isn’t where the manual he found on line that says it should be. Anybody have a clue? He’d like not to tear the airplane apart on a fishing expedition. Thanks! Quote
