Suffered minor damage during the air show when left gear collapsed on landing. Finally written off one month later after trying to land on Lake Constance (24 July 1985) The number 13 didn't bring luck to it! Another prototype was built and got the same registration 2 years later.

There are conflicting stories on D-ICDS. One is it crashed in 1985 and was not repaired. The registration was transferred to the second prototype (CD-2 c/n 1001). Another says it was rebuilt as more representative of the production aircraft. In that scenario, the second prototype (CD-2 c/n 02) was slightly larger and registered D-ICKS. Another source says the aircraft at Paris was the CD-1A c/n 01. That is what has been used here. D-ICDS at Paris 1987 had the shorter fuselage and round windows of the first prototype (CD-1) but the wing and pontoon design of the CD-2.
