HOW TO FIND PARTNUMBER IN BOEING AIRCRAFT : PART 2 #boeing

Short summary

This is a hands‑on tutorial (Part 2) showing how to find part numbers and installation procedures for aircraft wiring items on a Boeing 777 using the wiring diagrams/front matter, splice lists and the SWPM (Standard Wiring Practices Manual). It builds on Part 1 (contacts/wire full part‑number method) and covers shielded wires, splices (SM/SP), multi‑conductor cables, ferrules, grounding wire and grounding blocks.

Main workflow (how to find a part number / procedure)

1. Identify the symbol in the wiring diagram (e.g., circle = shielded single conductor, figure‑8 = twisted pair; suffix Z = shield).
2. Read the wire number (bundle + wire ID) and gauge/type code from the wire list.
3. Use the wiring diagram front matter to decode codes (SM vs SP, type codes, ferrule codes, FD, dot‑dot meaning, etc.).
4. Locate the partial part number or code family from the SWPM wire type tables (e.g., RO, R1) and construct the full wire part number (see Part 1 method).
5. For splices/terminals: check splice lists or front matter for item numbers and candidate part numbers (SM not listed in splice list; SP listed).
6. Cross‑reference SWPM chapters for installation procedures and exact part numbers for sleeves, sealed splices, heat‑shrink, solder sleeves, ferrules, grounding modules, and tools. Also check SWPM general chapters for material/temperature grades and wire OD when selecting sleeves/sleeve sizes.

Examples covered (explicit findings)

Example 1 — Contact #10 / wire 1003‑18 (shielded)

• Wire: 1003‑18, type RO, family AC, shield indicated (Z suffix). Shield status = DED (dead‑end) per wiring diagram.
• Splice: SM4 (splice within same bundle). Note: SMs are not listed in the splice list; SPs are.
• Actions:
  • Use the wire list to confirm gauge/type.
  • SWPM 2000‑13 (wire type codes) for partial part number of RO.
  • SWPM 2010‑15 (assembly of shield ground wires) → “assembly of shield dead end” for materials, heat‑shrink size and procedure.
  • SWPM 2030‑12 (assembly of splices) and front matter codes (example Delta 436‑36/37/38…) to select sealed butt splice part number and installation steps.
  • Also consult SWPM 2000‑11 (material & temperature grade) and 2000‑16 (wire outer diameter) for correct sleeve selection.

Example 2 — Contacts #8 & #9 / cable to DM52124 / wire 2002 B/R

• Wire: 2002, two conductors (blue and red), shielded, type R1, family JB, gauge 18.
• Action: Look up R1 in SWPM 2000 (type code tables) for partial part number and conductor count; combine with the Part 1 method to build the full part number. Note: one side shield dead‑ends, the other side grounds (covered in Example 3).

Example 3 — Shield grounding, ferrule and grounding block GB12662

• One end uses a ferrule (FD code) — decode ferrule identification in front matter; the other end terminates in a grounding block (GB12662).
• Use the wire list to find mating wire numbers (e.g., 0050), bundle, and contact type code (type 1 = terminal block contact).
• Find the grounding block part number in the wiring manual grounding list (WDM).
• Installation: SWPM 2010‑15 (assembly of shield ground) → choose the correct method: “solder sleeve without integral wire” when using a separate ground wire; the chapter lists sleeve part numbers, tool part numbers, cut lengths and steps. For grounding modules, SWPM 2090‑15 provides assembly/installation, contact part numbers, insertion/removal tools and diagrams.

Key SWPM / WDM chapters referenced (useful quick list)

• SWPM 2000‑13: Wire type codes (RO, R1, etc.) — partial wire part numbers and conductor counts
• SWPM 2000‑11: Material and temperature grades
• SWPM 2000‑16: Wire outer diameter (for sleeve sizing)
• SWPM 2010: Wire installation / repair (general)
• SWPM 2010‑15: Assembly of shield ground wires — dead‑end, folded back, adjacent, with/without integral wire, solder sleeves, heat‑shrink specs
• SWPM 2030‑12: Assembly of splices (sealed butt splice procedures and part numbers)
• SWPM 2090‑15: Grounding modules / grounding block installation and contact insertion/removal
• Wiring diagram front matter / splice lists / grounding lists / WDM: for code decoding and itemized part numbers

Parts, materials & tools mentioned

• Sealed butt splices (Delta 436‑36/37/38/40/41 series examples)
• Solder sleeves and heat‑shrink (with specific lengths/temperature specs per SWPM)
• Ferrules (FD codes), grounding blocks (GB12662 example), contact part numbers, insertion/removal tools
• Template sheet: recommended to capture bundle, wire number, gauge, type, family, splice item numbers, chapter references and notes (author uses one to track findings)

Other notes

• SM vs SP: SM = splice within same bundle (not listed in splice list); SP = splice between bundles (listed).
• Presenter frequently uses the front matter to decode numeric/type codes (e.g., code 9 = splice moisture seal).
• The video repeatedly cross‑references wiring manual data and SWPM chapters to pull both part numbers and precise installation procedures; temperature rating and wire OD are required to choose correct sleeve sizes and materials.

Main speaker / sources

• Speaker: the channel presenter (unnamed) who narrates the tutorial and demonstrates manual lookups.
• Primary sources used and cited in the video: Boeing wiring diagrams/front matter, wiring manual (WDM) grounding lists and splice lists, and the Boeing SWPM chapters listed above.

This summary can be turned into a concise checklist you can apply step‑by‑step when locating part numbers and installation procedures.
