Survivors

Approximately 30 ENMA Tigre IV engines remain airworthy in Britain (as of July 2009), all powering CASA 1.131 aircraft which are Spanish licensed-built versions of the Bücker Jungmann.[2]

Approximately 30 Tigre G-IV B engines are under restoration by the company Air Res Aviation located in Poland. The engines will be mainly intended for Bu-131 Jungmann's airplanes restored by Air Res Aviation.[3]
