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?

Off topic a bit but there is a Pegasus for sale on W&W for a very reasonable price. Depending on who you ask, similar and every bit as nice as a 19 and it likely has a higher max gross. The 3000 hour thing is no longer an issue. If I didn't already have a Peg, I'd be looking very seriously at this one. I'm just sayin'.

Quite possibly an estate sale from our club.
Yes, nice ship.
No, not crashed. Separate issue, but worth looking at.

Hello. I'm looking for a sailplane with my partner and we've come across a very nice ASW-19 that we are interested in. The aircraft has a maximum pilot weight of 196 pounds, which my partner just barely squeaks under with a parachute and will probably be over with drinking water and any other baggage. After reviewing the weight and balance documents, we noticed they were using 805 pounds as the max gross weight, but the manual states 899 pounds..

Further digging turned up the type certificate data sheet, which also shows 805 pounds as the maximum weight without water. Does anyone know why the FAA certified the aircraft with a lower max gross weight than stated in the manual? How are other owners dealing with this? If we took the glider experimental, would we be able to use the maximum gross number in the manual instead of the type certificate?

You don't sat where you or the glider is.

There is a pretty good Schleicher dealer (Williams Soaring) in the USA, call 'em up. If needed pay them to help you with a pre-buy questions and review of the log books etc. if needed. If the aircraft s anywhere near them get a W&B and pre-buy inspection done there.

With any doubt about W&B and past repairs, get a pre-buy W&B as well as inspection done, ideally with future owners in the cockpit.
