This Z-37 is in better shape since the last time I saw it as it now has wings, a tail and an engine. The wings likely came from OK-RJJ.

This aircraft was used between 1984 and 1985 to test the suitability of the Z-37T for military work. The aircraft was demilitarized and placed on the Czechoslovak civil register as OK-PJD in March of 1986. It was struck from the Czechoslovak register in 2005 and sold to a Hungarian owner. It sat derelict in outdoor storage in Hungary from 2005 to 2016. I took this picture of the aircraft about a month after a crew from Letecké Muzeum Kunovice brought it back from Hungary to restore it.

Ex OK-WIB

It doesn't look much but this Z-37 is in a bit better condition that previous photos on the web. There were guys working nearby on an An-2 so maybe this is slowly being put back together. The set of wings to the right belonged to OK-RJJ, possibly they are there to be mated to this hulk. Operated by Air Special

OK-PJD was photographed in 2009 engineless and derelict in Hungary.
