BÜCKER BÜ-131 "Jungmann" / C.A.S.A. 1.131 (E.3B) #lunesdeaviones

Video from the channel AmigosMuseoAire and J. Enríquez (jose-enriquez.es) about Bücker Bü 131 Jungmann, linked on its Above Ten Thousand entry. Duration: 7:41. Language: Spanish. Video type: Onboard.

A guide from the friends' association of the Museo del Aire, who trained as a pilot on this aircraft, tours the CASA 1.131 on display at the museum. It is the version built in Spain under licence from the Bücker Bü 131 Jungmann. He also shows the two engines displayed next to it.

He shows the steel tube structure, the wings made of small wooden ribs and the fabric covering, which in Granada was repaired by sewing. The aircraft weighed around 380 kg. It arrived with a Hirth engine of about 105 hp and later received a 150 hp Tigre engine made in Spain by Elizalde, mounted inverted. The control cables, the double set of ailerons, the pitot tube and the propeller are visible — a soldier would swing it by hand to start the engine. Also the narrow-track tailwheel gear, tricky on the ground and the cause of many incidents in gusty crosswinds, with almost non-existent brakes.

According to the guide, it is the most-built aircraft in Spain, with more than 580 units. It trained military pilots from 1941 to 1989, when it was replaced by the Pillán, after failed attempts to replace it with AISA light aircraft. The Fundación Infante de Orleans, next to the museum, keeps several airworthy and displays them on the first Sunday of each month.
