[John P Cooper]

Imformative thread - thanks ArtieBob. If somene kind sole can clairify the following for me I have another peice of the puzzle fall into place!

AB said:

1) Neubau = aircraft accepted immediately off the production line
2) Umbau = aircraft was modified
3) Reparatuer = ?

1) accepted by BAL? If so what is\was BAL
2) modified - does this mean that a factory conversion was completed (Umrust-Bausatze? Additionally is it not considered accepted until the modification was completed and then inspected?)
3) google translation = ???

Regards and sorry for what some of you will consider basic questions.
