During the testflight of the first Puma powered D.VII on Februay 25, 1921, the aircraft crashed, killing the pilot, Adolf Parge. During take-off, the pilot made a very steep climb, and started a turn to the left, when the engine stopped. The D.VII then stalled, and dived into the ground from a height of approximately 80 meters. The second Puma D.VII was flown succesfully on April 27, 1921 bij Lt. Versteegh.
The D.VII's were put into service in 1922, registered as 'F-301' to 'F-306'. The D.VII in the Dutch East Indies was not a succes. There were a lot of troubles with the engines and the synchronization mechanism. The last one was withdrawn in 1928.
