RECIPIENT BY ACCEPTING THIS DOCUMENT AGREES THAT NEITHER THIS DOCUMENT NOR THE INFORMATION DISCLOSED HEREIN NOR ANY PART THEREOF SHALL BE REPRODUCED OR TRANSFERRED TO OTHER DOCUMENTS OR USED OR DISCLOSED TO OTHERS FOR MANUFACTURING OR FOR ANY OTHER PURPOSE EXCEPT AS SPECIFICALLY AUTHORIZED IN WRITING BY MCDONNELL DOUGLAS CORPORATION. UNPUBLISHED - CREATED ON PREPARATION DATE OF THIS DOCUMENT. ALL RIGHTS RESERVED UNDER THE COPYRIGHT LAWS BY MCDONNELL DOUGLAS CORPORATION. DAC 25-1710 (REV. 5-90) DOUGLAS AIRCRAFT COMPANY CODE IDENT. NO. 88277 1. SCOPE 1.1 This Process Standard covers part and assembly identification and marking requirements and methods. 1.2 The requirements of this DPS are intended for identification after completion of all fabrication operations. Refer to applicable material specification (i.e. DMS, MIL-Spec, AMS, etc.) for required identification markings of extrusions, forgings and castings prior to final machining. Temporary identification by means of appropriate tags is recommended when parts are separated from their planning paper, such as in heat treating or chemical processing operations or when permanent markings are not required. 1.2.1 Tags or ties of metal are required to be of a metal in the same electrochemical group (see DPS 4.025) as the metal of which the parts are fabricated. 1.2.2 The requirements of this DPS are not intended to change normal Design Engineering and Planning operating practices unless specifically stated herein. Refer to the Boeing - Long Beach Division (LBD) Drafting Manual for aircraft design configuration control. 1.2.3 DPS 3.02 will define the part and assembly identification methods unless a specific alternate method of identification is specified on the LBD Engineering drawing. 1.3 The requirements of this DPS do not apply to the following: 1.3.1 Electrical Wiring (except assemblies); Commercial aircraft - See DPS 1.834-23 Military aircraft - See DPS 3.231 1.3.2 Contract End Items (no next assembly drawing). 1.3.3 For government applications, refer to DPS 3.02-17. 1.3.4 For supplier packaging requirements, refer to DPS 3.301. DPS 3.02 Rev. “BL” Page 2 of 25 MCDONNELL DOUGLAS CORPORATION - This information is subject to data rights legends on title page or first page. 1.4 In addition to the requirements of this DPS, other DPSs specify identification requirements, markings, and methods for the following: Bolts, Nuts and Screws Fluid (Plumbing) Lines Heat Treatment Inspection Operations Nonproduction Parts Rivets Raw Stock Metals Rubber Products Titanium Transparencies Washers Welding Wiring Assemblies Other specific materials, parts, or assemblies 1.5 Nameplate Substitution - Where Engineering drawings specify nameplates to be fabricated by the Graphotype machine process, photoetched nameplates fabricated per DPS 9.49 are acceptable. 1.6 Planning Assigned Identification Systems - Engineering assemblies, customer configurated by detail Finish Specification, and Planning assemblies may be identified with numerical and/or alphabetical systems that do not necessarily correlate to an Engineering assembly drawing. 1.6.1 Planning Variation Number - A Planning synthetic number which may be assigned to various types of assembly planning documents when an assembly is structured for a particular combination of engineering configurations. NOTE: Planning variation numbers are developed and assigned by Planning and are not to be confused with an Engineering Variation Drawing number. (Reference paragraph 4.1.1.2.6.) 1.7 Acceptance Stamps - Parts and assemblies require an acceptance stamp, subject to appearance and size limitations of this DPS, when manufactured to a LBD Engineering drawing or to a LBD Specification Control or Source Control drawing. The acceptance stamp is not a requirement on the following unless specifically required by the planning paper or purchase order. (a) Parts or assemblies with a supplier identification plate or label. (b) Supplier part numbered parts. (c) Industry standard drawings parts (e.g., AN, NAS, MS). (d) LBD Standards drawings parts. (If raw metal standards are reidentified, refer to DPS 3.54) DPS 3.02 Rev. “BL” Page 3 of 25 MCDONNELL DOUGLAS CORPORATION - This information is subject to data rights legends on title page or first page. 1.8 Supplemental Identification - In addition to the requirements of this DPS, parts and assemblies may require supplemental identification. Parts and assemblies manufactured at the Long Beach Division must be identified with the supplemental identification specified by that component of the Boeing Company for which parts are manufactured. As an example, LBD Fabrication (C1) procedures now specify to place Form No. 65-1307 on tagged parts which were dispositioned as “Use-as-is” or “Repair”. 1.9 Identification of Production Parts or Assemblies for Nonproduction Usage - Conforming production parts or assemblies required for Engineering Lab test, development, mockup, tooling or other nonproduction usage shall be identified as follows: 1.9.1 Nonproduction usage which may not render a production part unfit for later production usage shall be identified by stenciling the letters “XC-” , 0.25 inch high, or as large as possible (whichever is less), as a prefix to the production part or assembly number using red solvent removable coating (DPM 5404-9324). These parts, as prefixed, are not to be used in flight. EXAMPLES: XC-1234567-1 or XC-ABC4567-1 Note: All parts shall be reviewed after usage by Engineering to determine if nonproduction usage caused damage to the part. If deemed acceptable, the prefix shall be removed. 1.9.2 Nonproduction usage of a nonproduction part shall be identified by stenciling the letter “X-”, as a prefix to the nonproduction part or assembly number using red nonremovable coating (DMS 2433) per DPS 3.027 (Identification, Nonproduction Parts) to preclude the possibility of use as a production part or assembly. These parts are not to be used for any production requirement or installed on any aircraft. EXAMPLES: X-1234567-1 or X-ABC4567-1 1.9.2.1 Per DPS 3.027, the words “Not for Production Use” shall be applied when part size or configuration permits. A stripe shall be marked completely across the part when part size or configuration does not permit application of the words. 1.10 Interim Part Numbers - The requirements for interim part number identification are as defined in the Boeing - Long Beach Division Drafting Manual. Interim part numbers and methods of identification are listed as follows: 1.10.1 Interim part number suffixes are: ”Engineering Development Unit” (EDU), ”Pre-Production Unit” (PPU), and ”Flight Test Unit” (FTU). The Long Beach Division Drafting Manual defines the parameters for when to use these interim part number suffixes. DPS 3.02 Rev. “BL” Page 4 of 25 MCDONNELL DOUGLAS CORPORATION - This information is subject to data rights legends on title page or first page. 1.10.2 Interim part number suffixes are used on LRU components. An LRU is a component which can be replaced by line personnel without any configuration alterations (i.e., no drilling, reaming, cutting, filing, shimming, etc.). Examples of LRU’s include, but are not limited to: Electronic boxes (with or without software), actuators, valves, motors, sensors, switches, transducers, control panels, etc. 1.10.3 Interim parts and their special part number identification are not applicable to parts that are primary structure (i.e., Principal Structural Elements (PSE’s), fuselage, wing, empennage, pylon, landing gear, etc.) or secondary structure (i.e., interior, radio racks, electrical power center, flight surfaces, cargo handling systems, doors, ducts, etc.). 1.10.4 Use of interim part number suffixes must be approved on Vendor Information Request (VIR) and authorizing Purchase Order (PO) or Purchase Order Change Authorization (POCA). These suffixes are only required for parts being delivered to the Long Beach Division. (LBD). NOTE: These suffixes are a LBD interim identification only, controlled by a LBD drawing and do not deviate or require a supplier drawing change. 1.10.4.1 Engineering Development Unit (EDU) - A blue identification label shall be used. 1.10.4.2 Pre-Production Unit (PPU) - A yellow identification label shall be used. 1.10.4.3 Flight Test Unit (FTU) - A red identification label shall be used. 1.10.5 EDU, PPU and FTU interim-identified parts must be replaced with a production part or be reidentified with a production part number prior to obtaining a Certificate of Airworthiness. NOTE: EDU’s can not be reidentified and must be replaced. 1.10.6 The method of identifying interim part number suffixes, unless otherwise specified on a VIR (as referenced in paragraph 1.10.8 ”NOTE”), shall be as follows: A temporary label shall be affixed over the production part number and shall completely cover/obscure the part number. 1.10.7 The label will be of the appropriate background color, EDU - Blue, PPU - Yellow and FTU - Red, with black lettering. 1.10.8 The temporary label material and method of attaching it shall be such that it will remain firmly affixed throughout handling, installation and testing. Clear mylar tape, such as DPM 895, may be placed over the label to enhance its fluid and abrasion resistance. NOTE: Special ID instructions may be required due to environmental exposure of the part (i.e., heat, oil, water, rubber and movable parts.). These instructions shall be documented and approved on the VIR. DPS 3.02 Rev. “BL” Page 5 of 25 MCDONNELL DOUGLAS CORPORATION - This information is subject to data rights legends on title page or first page. 1.10.9 The label shall be removable without marring the ID of the part. It shall contain the complete part number, appropriate suffix and serial number (when applicable). Example: LBD or Supplier Part Number (FTU condition shown). SN - XYZ XXXXXXX - XXX FTU Label with appropriate background color (blue, yellow or red) Suffix (EDU, PPU or FTU) LBD or Supplier part number with dash & dash numbers (as applicable) with black lettering Serial number (when applicable) 1.10.10 When a supplier end item deliverable part, subassembly, assembly (Engineering or Planning) that contains a detail with an interim part number suffix, the end item delivered to LBD must be identified with ”IP (Interim Part) and Planning Designated number” as call for on the Planning Form 33-68, PO or POCA. NOTE: When interim parts are shipped in a kit, the kit number must also carry the ”IP and Planning Designated number” identification. Example: Part ––––––––––– Sub Assembly –––––––––––– Assembly ––––––––––––––– Kit XXXX-1 ”FTU” XXX-501 ”IP3” XXXX-901 ”IP3” XXXX-903 ”IP3” Required per VIR Required when end item Required on end item Only required when end item is shipped within a kit 1.10.11 Removal or Reidentification - Detail parts identified with an interim part number suffix will be removed or reidentified with the release of a ”Production Assist” drawing along with released planning AAO instructions for LBD in house parts and VIR, PO, RPO or POCA at the supplier (when applicable). 1.10.12 Testing of Parts (Interim, Production and Nonproduction) at Supplier’s Facility or Subtier 1.10.12.1 Supplier must identify any part that is used for test with a unique identification as to not allow them to be commingled with other production parts. NOTE: These parts do not require the use of LBD prefixes or suffixes if they are not being delivered to LBD. 1.10.12.2 The supplier must have a documented process for the handling and use of this unique identification. DPS 3.02 Rev. “BL” Page 6 of 25 MCDONNELL DOUGLAS CORPORATION - This information is subject to data rights legends on title page or first page. 1.10.12.3 The supplier shall submit any tested part along with all test documents to LBD MRB Engineering and Supplier Quality prior to reentering the part into the production system. 1.11 To improve understanding of the requirements of this DPS, certain terms are defined as follows: 1.11.1 Part - One piece, or two or more pieces joined together which are not normally subject to disassembly without destruction. Exceptions are assemblies containing Long Beach Division numbered parts which may be subject to change activity independent of the next assembly drawing and/or purchase parts. 1.11.2 Subassembly - Two or more parts which form a portion of an assembly or a unit replaceable as a whole, but having a part or parts which are individually replaceable. 1.11.3 Assembly - A number of parts or subassemblies or any combination thereof joined together to perform a specific function. 1.11.4 Engineering Assembly - An Engineering assembly is built exactly to an Engineering assembly drawing. 1.11.5 Planning Assembly - A planning assembly is not built exactly to an Engineering assembly drawing. 1.11.6 Planning Edition Number - A sequential change number assigned by Production Planning to an assembly which identifies that a physical change caused by either Engineering or Production Planning has been made affecting fit, form, or function. 1.11.7 Unit - An assembly or any combination of parts, subassemblies and assemblies mounted together, normally capable of independent operation in a variety of situations. 1.11.8 Set - A unit or units and necessary assemblies, subassemblies and parts connected or associated together to perform an operational function. Also used to denote a collection of like parts such as a “tool set” or a “set” of tires. 1.11.9 Acceptance Stamp - An inspection stamp of LBD, other Boeing components or suppliers. 1.11.10 Factory Serial Number (FSN) - A permanent, unique number assigned to each end item product manufactured by LBD for the purpose of customer and configuration identification. The FSN is independent of assembly line sequence. 1.11.11 Serial Version Number Control (SVNC) - A practice used in lieu of Factory Serial Number Control to manage traceability and accountability requirements for nonconfigurated assemblies. SVNC uses the supplier’s serial number in conjunction with a version number. 1.11.12 Fuselage Number - The chronological assignment and schedule that an aircraft is produced in sequence to other aircraft. 1.11.13 Version Number - A 3-digit number assigned by LBD Planning used to identify physical changes to SVNC assemblies.

REQUIREMENTS 4.1 Parts and Assemblies - All parts, subassemblies and assemblies as specified on the purchase order or Long Beach Division inplant build paper shall be identified by methods specified herein and as follows: 4.1.1 Part Identification (see definition in paragraph 1.10) - The part number and the change letter of the latest EO affecting the part, or (N/C) where no change letter exists, shall be applied. The change letter shall be separated from the part number by a minimum distance of two times the distance between the spacing in the part number. NOTES: (1) If the assembly EO does not affect the part, no revision letter change is to be made. (2) Parts identified as “NC” change will be considered equivalent to “N/C” unless otherwise proved by an Engineering Order. The designation of N/C for drawings with no change letter was established in Revision “BH’ change of this DPS in March of 1999. If in doubt as to what the most recent letter change is, contact M&PE. EXCEPTIONS: Identification is not required for: (1) Details of a weld assembly that cannot be removed from the completed assembly. The weld assembly is considered to be one part.
