Airframes paperwork

[fran]

Hello,
What is the german name for the papers/form where an airframe (and its motor) had annotated their hours of flying time? Who were tasked in fullfit them? the unit's chief mechanic of every aircraft? The TO?
When a LW recovery team takes an crashed/damaged aircraft from the front, to a repair/remanufacturing stablishment, also takes care of asking the papers to parents units to follow its records when assigned to other unit?

Best regards
Francisco
