Ours is down for maintenance (and perhaps a new engine, I don't know) anyway and I'll be at the club this afternoon so I'll give it a look.
Well, didn't get a chance to talk to anybody knowledgeable about what's wrong with our bird, and forgot to go out and look for whatever is placarded near the cigarette lighter socket. But I did see another DA-40 TDI, belonging to another flying club based at the same airport, without a prop and the resulting hole in the cowling taped off with clear plastic sheeting. They must expect that that one is going to be grounded for a while to do that.
(I did have a tremendous time on my first solo aerobatics sortie though!)
