Anyone ever have an accessory drive come apart and take the engine out with it? The 404 I had been flying had it happen on a 200 hour engine. Thankfully it was covered on the RAM warranty. Just wondering if that was common at all.

Never had a gearbox come apart, although I've blown jugs off of Continentals. I flew a 421A years ago, straight wing, nice airplane. Iirc, the propellers would drive the engines on power reduction, so I never reduced the power below 20" until over the fence.

Did anyone ever feather the engine and then restart it in flight? That is a major no no with the GTSIO engines. The MX manual says that if the engine has over 200 (?) hours on it, and is feathered and restarted in flight it must be overhauled. It creates some horrible stresses on the gear reduction.
