Precision CNC Machining for Renton Aerospace Teams
Aerospace suppliers feeding the Boeing Renton Factory need parts that are flight-critical, fully traceable, and aligned to Boeing D1-9000-1. A 2024-T3 fuselage frame that is 0.01 inch off will fail a skin-splice fit check. A 7150-T77511 wing spar cap that doesn't hit its web-thickness callout will trigger a nonconformance at the wing-build cell. RivCut machines narrow-body aerospace parts to ±0.005" profile and ±0.0005" bore tolerances, runs AS9102 first-article inspection on every new part number, and supplies MMPDS-2024-traceable material certs tied to Boeing D6-82479 approved-source mills.
AS9100-Aligned Documentation
Ballooned AS9102 FAIR, D1-9000-1 AQS supplier package, Boeing D6-17487 narrow-body process compliance, and ITAR-registered chain of custody for P-8 work — complete documentation on every job.
Narrow-Body Aerospace Materials
2024-T3/-T351, 7075-T6, 7150-T77511 spar caps, Ti-6Al-4V AMS 4928 pylon brackets, 4130/4340 steel landing gear hardware — all with heat-lot traceability to MMPDS-2024.

What We Machine for Renton Aerospace Teams
The Boeing Renton Factory supply chain runs on narrow-body fuselage frames, titanium pylon brackets, and ITAR-controlled P-8 hardware. We cut all of it to Boeing documentation discipline.
2024-T3 Fuselage Frames & Shear Ties
Fuselage frames and shear ties machined from 2024-T3 sheet and plate for the 737 MAX narrow-body. Profile tolerance ±0.005" over the full frame circumference ensures skin-splice fit at every station. MIL-DTL-5541 Alodine 1200S finish and ballooned AS9102 FAIR on every lot.
2024-T3, ±0.005" profile, MIL-DTL-55417150-T77511 Wing Spar Caps
The 737 MAX wing spar caps are extruded from 7150-T77511 — the highest-strength aluminum alloy in commercial aviation. Web-thickness control is critical: dimensional deviation at the spar cap drives the wing bending stiffness allowable. We machine spar cap blanks to net section dimensions with full web-thickness callout compliance.

7050-T7451, monolithicRenton's Narrow-Body Aerospace Ecosystem
The Boeing Renton Factory and the King County narrow-body supply chain form one of the most focused aerospace production ecosystems in North America — and RivCut is your Pacific-coast precision machining partner into it.
World's highest-rate commercial jet program
The Boeing Renton Factory at 737 Logan Ave N runs the fastest commercial jet assembly operation on earth — 38 to 42 737 MAX aircraft per month across three lines. Every frame, fitting, and bracket feeding those lines is a supply-chain opportunity for precision machine shops aligned to Boeing D1-9000-1.
P-8 Poseidon — Renton's defense angle
The P-8 Poseidon is assembled on the same Renton floor as the 737 MAX — a militarized 737-800NG flown by the US Navy for anti-submarine warfare and operated by 8+ allied nations. P-8 ITAR work requires registered handling that most machine shops cannot provide.
Exotic Metals Forming — titanium pylon/nacelle parts 0.8 mi from factory
Exotic Metals Forming at 1625 E Valley Rd in Renton is one of Boeing's key titanium nacelle and pylon component suppliers — located just 0.8 miles from the 737 Logan Ave N factory gate. Precision machined metallic components flow directly into their titanium-forming and welding operations.
King County narrow-body supply chain — from Auburn to Kent Valley
GKN Aerospace in Auburn, Safran Landing Systems, Blue Origin in Kent, and dozens of tier-2 suppliers form a dense narrow-body and defense supply chain across King County. RivCut machines into this network from our Union City, CA facility with next-day LTL to 98057.

Built for Renton's Narrow-Body Aerospace Supply Chain
Renton is not a generic aerospace city. It is the narrow-body aerospace city. The Boeing Renton Factory at 737 Logan Ave N runs the world's highest-rate commercial jet assembly operation — 38 to 42 737 MAX aircraft per month across three active lines with approximately 15,000 Boeing employees. The 737 MAX airframe contains roughly 400,000 parts, and every fuselage frame, wing spar cap, pylon bracket, and keel beam fitting feeding those lines must meet Boeing D1-9000-1 documentation discipline and D6-17487 narrow-body process compliance. Add the P-8 Poseidon ITAR program assembled on the same factory floor, Exotic Metals Forming 0.8 miles from the factory gate, GKN Aerospace in Auburn, Safran Landing Systems, and the Blue Origin supply chain in Kent Valley, and the King County narrow-body ecosystem becomes one of the most focused aerospace production clusters in North America. RivCut machines into that supply chain: 2024-T3 fuselage frames, 7150-T77511 spar cap blanks, Ti-6Al-4V AMS 4928 pylon brackets with ±0.0005" bore, and ITAR-registered P-8 hardware — all shipped with ballooned FAIR, mill certs, and D1-9000-1 documentation aligned to Boeing D6-82479 approved-process sources.
