I just want to see if I have some of the facts correct that I have pieced together on the Bauaufsicht (Construction supervision) and especially Nr.13 assigned to the Fokker Flugzeugwerke. All of this information I have pieced together from lots of posts that Dan-San has made, I want to thank him for all his knowledge on this subject.

The Bauaufsicht was under control of the Idflieg and numbered 1-45 (with the exception of there was no Nr.28) and were subordinate to Inspektion des Flugzeugwesens, and Zentral=Abnahme=Kommission (ZAK)..

The responsibility of the Bauaufsicht was to oversee each aircraft manufacturer conformed to the BLV (Bau-und Lieferungsvorschriften für Militärflugzeug (Building and supply regulations for military aircraft)

The Fokker Flugzeugwerke was assigned Bauaufsicht Nr.13 that also included responsibly for the inspections at Gebrüder Perzina Werk I and II and Pianofortefabrik Nützmann.

Bauaufsicht Nr.13 was commanded by Ltn.Rodhe and in his staff were two officers, Ingenieur des Inspektion (engineer inspection), Ingenieur Betsch (engineer Betsch),
4 Werkmeister=Diensttuern,(Foreman, on duty)
2 Unteroffizern,
11 mann für Bureau und Betrieb,(Office and Management)
1 Nachflieger.(Flight test pilot?)

From the acceptance reports that we do have from the Fokker Flugzeugwerke shows more the 1 Nachflieger, Grosse, Weidner, Schutzemeister, Mathais, Niesen and Petermann makes 6 Nachflieger’s.

At the Fokker Flugzeugwerke, Bauaufsicht Nr.13 worked out of Gebäude Nr.11 one of the smaller buildings located on the property on the north end next to Halle 1.

The responsibility of the Bauaufsicht personal was to oversee all aspects of the manufacture. For nuts, bolts, rivets, turnbuckles, taps, dies, etc there were in Berlin a Bauaufsicht went to the various companies to check those types of items for compliance and acceptance before they could shipped to the aircraft manufacturer. The same went for wheels, radiators, propellers that the manufacturer would order.

If a required marking was missing, the aircraft would be rejected and sent back for correction. The BLV requirements are very specific. Every part of the aircraft was subject to inspection by the Bauaufsicht Inspectors during the manufacturing processes as well as final inspection. For example, wing ribs were marked to identify the ribs say a Fokker D.VII urpper wing the ribs were marked from the center upper right third rib would be marked o3r, o = ober (upper) 3 rib number, r= recht (right) and marked in black ink in the middle of the rib between the spars on the inside face. While the corresponding rib on the left side is structurally and dimensionally identical, but because of the marking, becomes unique. In the acceptance documents every part is listed by maker, part number and serial number, gas tanks, oil tank, exhaust pipe, radiator, wheels, etc.

I would be interested if you have any thing to correct or add.

Dan-San has mention that he has some of the BLV documents and amendments. Are these available, I understand that these are in German and I would like them translated. I would really like to see if I could have them translated.
