Michael, I replaced them for two reasons, when all this AD talk started I ordered a new Tube and Horn from Piper over a year ago, so I had a new set, secondly, I am not a big fan of tearing apart airplanes in annuals, especially things like the rear of the plane, that said, the new Horn and Tube guarantees 1000 HRS of good flying with no more inspections.
