Here is a copy FAR 43.2 describing the difference of a rebuild and an overhaul. All compenents are treated the same, even though we normally relate overhaul with engines and rotating components because they wear differently. Rotating parts generaly have a direct corralation between hours operated and amount of wear. Obviously airframes wear out also and also need overhaul or rebuilding even though it's difficult to set a time before overhaul. A good example af an airframe with a TBO is the Robinson helicopter, of course most of the airframe is rotating.

(a) describes overhaul where (b) describes rebuild. Some key words being "acceptable to the administrator" "tested"

§ 43.2 Records of overhaul and rebuilding.
(a) No person may describe in any required maintenance entry or form an aircraft, airframe, aircraft engine, propeller, appliance, or component part as being overhauled unless—

(1) Using methods, techniques, and practices acceptable to the Administrator, it has been disassembled, cleaned, inspected, repaired as necessary, and reassembled; and

(2) It has been tested in accordance with approved standards and technical data, or in accordance with current standards and technical data accepteble to the Administrator, which have been developed and documented by the holder of the type certificate, supplemental type certificate, or a material, part, process, or applicance approval under §21.305 of this chapter.

(b) No person may describe in any required maintenance entry or form an aircraft, airframe, aircraft engine, propeller, appliance, or component part as being rebuilt unless it has been disassembled, cleaned, inspected, repaired as necessary, reassembled, and tested to the same tolerances and limits as a new item, using either new parts or used parts that either conform to new part tolerances and limits or to approved oversized or undersized dimensions.

Here is a copy FAR 43.2 describing the difference of a rebuild and an overhaul.

Where does it say that a rebuild,or being rebuilt can be called zero timed when not done at the factory? I don't think you can say zero time.
