Excellent follow-up by Schempp-Hirth!
The problem with the Duo could not have happened at a worse time.
Right in the middle of the soaring season and the Schempp-Hirth factory on holiday. A lot of SHK workers volunteered to skip their vacation and help out with the inspections that started already started last weekend. I made the 700 Km drive to Kirchhein on Sunday afternoon. Next day SHK workers were already busy from 7 AM. The inspection procedure is rather simple. One team is taking care of the removal of ailerons and drilling inspection holes. After that the inspection team comes in with a boroscope. If no defects are found, the holes in airbrake box are repaired; the 2 small holes (12 mm) in the lower skin are reinforced with epoxy and covered by tape. Ailerons installed , paper work done and you're out in about 3 to 4 hours. Unfortunately the left wing of my Duo had a 4 cm defective bond near the wing tip and repairs were needed. From that entire number of Duo's present at that time; there was one other Duo who needed similar repairs. They had to cut out a few small panels in the underside of the wing to make repairs to the bonding of the spar. After this they had to repair the cut-outs and restore the finish. This took about 24 hours of extra time. Next week the CS factory that manufactures most of the Duo parts will be back from vacation. A hefty investigation will start… |

Ruud,
How old is your Duo - and did you find out how old the other one at the factory was? I am hoping that the production problem is of recent duration and not spread thoughout all ages of the fleet. Our Duo T S/N 35 was delivered in December 2001 and has not been inspected yet.

It is great that SHK is taking their responsibility. But, .... is not this what we should expect? Obviously (as your Duo also had defect bondings), there are problems with the Duo, and it seems to be poor manufacting procedures. As customers should we not demand the manufacturer to cover all costs for inspections and repairs? So why should we give credits to some one who appearantly did a really bad job? If SHK will cover all costs for the inspections, including travel, lost income due to lost flying time etc etc, it is OK for me.
