Dan: That makes sense. Thanks. We will definitely be looking for excess weight in the tail. Any idea where one might put such weight?

Michael: I see the TN on Schliechers website, but the TCDS says that the max weight without water is the same for both ASW-19 and ASW-19b, so I don't think that will help me.

Tom: Yes. This glider has a standard certificate. I find it hard to believe that a mistake like that could remain unchanged for so many years!

It just might be a typo by the issuing FSDO (805 vs 895).

From TCDSs for ASW19/ASW19B, EASA max weight dry: 805 lbs for both. Transport Canada max weight dry: 805 lbs for both. BGA max weight dry: 805 lbs for both. With FAA, that would be 8 typos - 4 per 19, 4 per 19B... Therefore, not an FAA typo.

As for where weight might be, from BGA TCDS: "Up to 7 Kg of nose weights may be fitted. 1 Kg of nose weight is equivalent to 2.5 Kg of cockpit weight".

BGA gives weight of non-lifting parts ("everything except wings") as 507 lbs. When you weigh for new CofG, weigh that. It should give an idea of whether repair added a bunch of weight - the fuselage and tail are easy to weigh.

Then, WHY does this differ so much from the manufacturer's, Schleicher's, published weights?
