This Let-410 was built as a 'M' and delivered to the Czechoslovak AF in December 1975. It was fitted with Walther M601A engines and converted to 'MA' standard. In January 1993 it was transferred over to the Czech AF and around 2006 it visited Aerotech at EDBR and evidently never left. The plane is now privately owned and on loan to the Luftfahrttechnischer Meseumverein Rothenburg for display.
