Description:
TECHNICAL FIELD 
       [0001]    The disclosure generally relates to data archiving systems and methods. More particularly, the disclosure relates to an onboard data archiving system and method which are suitable for managing structural repair data onboard an aircraft. 
       BACKGROUND 
       [0002]    In the repair of a structure such as an aircraft, paper and digital repair records may be required for repair authorization. However, archiving of repair records may be a manual and imprecise process. Significant time and effort may be expended to locate the repair records when they are needed. Repair records may be particularly important if a new repair which is physically close to or affected by an earlier repair is needed. 
         [0003]    Current maintenance and repair methods may require a time-intensive process of cleaning and removing corrosion prior to performing non-destructive testing (NDT) to check for further need for repair. Under circumstances in which the part having the repair surface had previously reached the limit for material removal, the part may require complete replacement, rendering the cleaning and corrosion removing process unnecessary. 
         [0004]    Therefore, an onboard data archiving system and method are needed in which repair records are stored on a repair surface adjacent to or near a repair area of a structure and are easily downloaded and transmitted to maintenance engineering personnel. 
       SUMMARY 
       [0005]    The disclosure is generally directed to a data archiving system. An illustrative embodiment of the data archiving system includes an archiving label including a label tag and a memory device carried by the label tag and a reading device adapted to retrieve repair information from the memory device. 
         [0006]    The disclosure is further generally directed to a data archiving method. An illustrative embodiment of the data archiving method includes affixing an archiving label having a label tag and a memory device carried by the label tag to a repair surface in vicinity of a first repair area; receiving archived repair information pertaining to the first repair area; and uploading the repair information to the memory device. 
         [0007]    In some embodiments, the data archiving method may include affixing an archiving label having a label tag and a memory device carried by the label tag to a repair surface generally adjacent to a first repair area; receiving archived repair information pertaining to the first repair area; uploading the repair information to the memory device; retrieving the repair information from the memory device during subsequent repair in vicinity of the first repair area; and providing the repair information to a manufacturer for disposition of the subsequent repair.

     DETAILED DESCRIPTION 
       [0016]    The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” Any implementation described herein as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the invention and are not intended to limit the scope of the invention, which is defined by the claims. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. 
         [0017]    Referring initially to  FIGS. 1-3 , an illustrative embodiment of the onboard data archiving system, hereinafter system, is generally indicated by reference numeral  1 . The system  1  may include an archiving label  2  which may include a label tag  3 . The label tag  3  may be any desired size and shape and may be paper, plastic, composite and/or other material. The label tag  3  may have a visually distinguishable tag surface  3   a  and an adhesive surface  3   b  ( FIG. 2 ). The visually distinguishable tag surface  3   a  may have an appearance which may be used to easily visually distinguish the label tag  3  from a surrounding repair surface  12  to which the archiving label  2  is applied, as will be hereinafter described. In some embodiments, the visually distinguishable tag surface  3   a  may have an appearance such as, for example and without limitation, a single color (such as orange) or a combination of colors; a pattern of lines or symbols; or any combination thereof. As shown in  FIG. 2 , an adhesive layer  4  may be provided on the adhesive surface  3   b  of the label tag  3  to facilitate attachment of the archiving label  2  to the repair surface  12  ( FIG. 1 ). 
         [0018]    A solid state memory device  8  may be provided on the visually distinguishable tag surface  3   a  of the label tag  3 . The solid state memory device  8  may be any type of device which is capable of receiving, archiving and storing repair information  20  and facilitates selective retrieval of the repair information  20  such as by using a reading device  18  which is suitable for the purpose. The repair information  20  may include such information as the details of the repair procedure and the history of a repair, for example and without limitation. In some embodiments, the solid state memory device  8  may be a contact data button. In some embodiments, the solid state memory device  8  may be an RFID (Radio Frequency Identification) tag. In other embodiments, alternative solid state memory devices  8  which are known by those skilled in the art and are suitable for the purpose may be used. The reading device  18  may be capable of retrieving the archived repair information  20  from the solid state memory device  8  and displaying the retrieved repair information. A transmitter  19  may interface with the reading device  18  to transmit the repair information  20  from the reading device  18  to a manufacturer  10 . 
         [0019]    As shown in  FIGS. 1 and 3 , in exemplary application of the system  1 , repair personnel (not shown) may initially transmit a repair request to a manufacturer  10  for repair of a structure  11  such as an aircraft, for example and without limitation. The manufacturer  10  may review the repair request and suggest a repair procedure for the structure  11 . The repair personnel may accept the repair procedure and ask the manufacturer  10  for repair authorization. The manufacturer  10  may release a repair authorization and transmit repair information, which may include repair data, drawings, details of the repair procedure and history of the repair, for example and without limitation, to the repair personnel. The manufacturer  10  may additionally release authorization for programming of the memory device  8  of an archiving label  2 . 
         [0020]    After the repair personnel completes a first repair on a first repair area  14  ( FIG. 3 ) on the repair surface  12 , the repair personnel may program the repair information into the memory device  8  of the archiving label  2 . The repair personnel may then affix the adhesive layer  4  on the label tag  3  to the repair surface  12  generally at or adjacent to the first repair area  14 , as shown in  FIG. 3 . 
         [0021]    At some point in time after completion of the first repair, the first repair area  14  may be opened for future repair or inspection. This analysis may necessitate that a second repair be carried out at a second repair area  15  which may overlap or be in close proximity to the first repair area  14 . Accordingly, the repair information which was previously archived and stored on the memory device  8  of the archiving label  2  may be downloaded to the reading device  18 . The repair information  20  may be de-encrypted and transmitted with a second repair request to the manufacturer  10 . The manufacturer  10  may use the repair information  20  which pertains to the first repair area  14  to formulate a second repair procedure which is to be used to implement a second repair at a second repair area  16  which is coincident with or adjacent to the first repair area  14 . The visually distinguishable tag surface  3   a  of the label tag  3  may enable repair personnel to readily locate the first repair area  14  on the repair surface  12  and to distinguish among multiple repair areas on the same repair surface  12 . Therefore, repair information which relates to the first repair and is pertinent to a second repair to be carried out at the second repair area  15  may be properly analyzed to optimize repair of the second repair at the second repair area  15 . The archiving label  2  may render historic and other data which relates to a previous repair easier to access in finding and considering previous repairs when performing maintenance on an airplane or other structure. Moreover, repair information which indicates previous removal of material from the repair surface  12  may limit rework, galley sub-floor repairs, scratch/dent management, one-off modifications (airframe, component, power plant, avionics and electrical) which may otherwise be difficult or impossible to identify. 
         [0022]    It will be appreciated by those skilled in the art that the system  1  provides a visual cue for repair personnel which facilitates ease in locating a repair area on a repair surface and accessing information relating to a repair which was previously carried out at the repair area. The system  1  may facilitate instant recovery of detailed repair information which can be transmitted to a manufacturer or other entity for disposition and reduce unnecessary rework. In some applications, a data file may be provided for programming the memory device  8  upon completion of a repair. The memory device  8  may then be programmed by repair personnel and the archiving label  2  affixed to the repair surface  12  next to the first repair area  14  prior to closing out the first repair area  14 . Data files stored on the memory device  8  may be encrypted for security, with un-encryption only possible by authorized personnel. Encryption of the data files may also be of a type which is readable by only the current owner of the airplane or other structure. This may ensure data security to the owner and allow the owner to control the release of sensitive data to future owners of the airplane or other structure. 
         [0023]    Referring next to  FIG. 4 , a flow diagram  400  which illustrates an exemplary method of programming and installing an illustrative embodiment of the onboard data archiving system is shown. In block  402 , a repair request is received by a manufacturer of the structure which is being repaired. Repair personnel may transmit the repair request to the manufacturer. In block  404 , the repair request is reviewed by the manufacturer and a repair procedure is suggested. In block  406 , the repair procedure is accepted by the repair personnel and the repair personnel seeks repair authorization. In block  408 , repair authorization is released by the manufacturer. Repair information, which may include repair data, drawings, repair procedure details and repair history, for example and without limitation, is transmitted from the manufacturer to the repair personnel. Authorization for programming of an archiving label with the repair information is released by the manufacturer. In block  410 , the repair is completed and the archiving label is programmed with the repair information. In block  412 , the archiving label is affixed to a repair surface in general proximity to a repair area in which the repair was made. 
         [0024]    Referring next to  FIG. 5 , a flow diagram  500  which illustrates an exemplary method of using an illustrative embodiment of the onboard data archiving system is shown. In block  502 , a repair area which may be in the vicinity of a first repair area is opened for future repair or inspection. In block  504 , repair information which may affect the second or current repair or inspection is downloaded from the archiving label. In block  506 , the repair information may be un-encrypted. In block  508 , a repair request for the second repair, along with the repair information for the first repair, is transmitted from repair personnel to a manufacturer. Steps  402 - 412  which were set forth hereinabove with respect to  FIG. 4  may follow block  508  in  FIG. 5 . The manufacturer may use the repair information which pertains to the first repair area to formulate a second repair procedure which is to be used to implement the second repair at the second repair area which is coincident with or adjacent to the first repair area.
