History of the BITZ Company


The company was established as a carpentry after the war 1946 by Josef Bitz.

Before he was employed since 1933 at the Bavarian airplane-works (BFW), later changing into the famous Messerschmitt Company. Working there up to the end of the war. Finally as chief inspector for the aircraft Me 321 and 323 “Gigant”.

In the carpentry, furnitures, cinema-folding chairs, booths, small ready-houses were manufactured and he developed a new manufacturing procedure for leg-prostheses, that was sold to the famous Professor Sauerbruch at Berlin.

As his whole heart beat for flying however, immediately after glider flying was allowed again, several types of wings for the "Scheibe Flugzeugbau" were produced.

Furthermore the homebuild „Libelle“. Later as the "Schleicher"-Co. could not manage all orders for Ka 6 gliders the BITZ Co. built new Ka 6 in license and took care of a big number of repairs.

Airplane-parts were built for the "Meindl" A-15 and A-150 aircraft and a two-seater motor-airplane, that didn't reach the series-production however, for the Italien Mantelli.

Heini Dittmar, the well known Messerschmitt-testpilot contacted BITZ and ordered the building of his own design "Möve" light aircraft. BITZ manufactured some kits for homebuilders. Through former friends of the Messerschmitt-Co. , then with the "Flugzeug-Union-Süd" Co., contact was made with the film-company Centfox and built for the famous film „Blue Max “1965 within a half year 2 flying examples of the Fokker DRI. From this, the acquaintance originated with the American Jack Canary, who was enthusiastic for the airplane Bücker 133-“Jungmeister”.

From the year 1967, based on Canary's positive market study in the USA, BITZ started production of the Bücker 133 "Jungmeister" based on original drawings aquired from Spain by Mr Clemens Bücke himself. After more than 1 years of jig-construction and production, the first new Bü 133 “Jungmeister”was flown at Nabern-Teck by the LBA Stuttgart pilot Mr. Schäfer. As second pilot count of Hagenburg was engaged and flew his complete world champion aerobatic program on the first BITZ-Bücker. Due to limited capacity at BITZ the final work, testflying and shippment on the Bücker 131 was done by the Hirth Co. at Nabern-Teck. After the delivery of the 4. Bücker Jack Canary died during a ferry flight of a Warbird and the project came to the halt.

After that spare parts for all Bücker types were built for foreign coustomers, as in Germany the flying of oldtimest started about 1979 gradually to be popular.


In 1975 Josef Bitz died and according to his wish his daughter and son-in-law Josef Griener continued the business under the name Bitz GmbH.

Josef Griener came 1960 into the company and learned from Josef BITZ the way to build and repair aircraft efficiant with limeted recources.


A wide spectrum was built this time of airplane-types and repairs and static and flying types for the movie industry.:

- Fuselage for the historic Racingplane Deperdussin.

- Morane undercarriages, tail units.

As 1979 the first Bückers 131, the so-called „CASA Bücker “, were imported from Spain. The LBA authorized the Bitz GmbH with the responsibility for certification and main overhaul for the CASA-Bücker based on the BITZ experience with the Bücker aircraft types.

Some years later, the BITZ GmbH got the admission of the LBA to install Lycoming 160 and 180 HP engines into Bücker aircraft, modification to hydraulic brakes and certification for glider towing. Up to now 15 modifications have been done by BITZ for customers in for Germany, England, France and Switzerland.
