An instructional airframe with TsLw3 at Fassberg. D-CARL is a fake registration. The 7Wing marking is unknown, but may refer to RAF's No.7 Wing which operated from Fassberg during the time of the Berlin Airlift. A remnant of its former identity is on the tail.
Even though there is no ID visible, it is thought that this is the third prototype of the L-410. There were four prototypes, two of which are in Kunovice, one was used for structural testing possibly to breaking point and the fourth is in Kbely.
This L-410 was delivered to the Czechoslovak AF in July 1975. It was converted to MA-standard (with Walter M601B engines) and then transferred to the Slovak AF in January 1993. It is now on display at the Vojenské Historické Múzeum at Pieštany,
This unmarked Turbolet, not the best picture but 9Qs are interesting, was seen during its take-off from Goma. It's not clear to what company the aircraft belonged at that time, but most probably it was registered with Safe Air Company. CUB was last noted at Bukavu-Kavumu in May 2010, when it was parked in the grass after an accident (dented nose).
