CNC Machined Landing Gear Components for Aerospace Teams
Landing gear teams in Chicago need parts that are strong, precise, and traceable. We machine 4340 steel, 300M, and titanium 6Al-4V landing gear components with tight bore tolerances. CMM inspection and AS9100D-aligned documentation on every order.
High-Strength Alloys
4340 steel, 300M, and titanium 6Al-4V with mill certs and traceability.
Bore Precision
±0.0005" on critical pin bores and sealing surfaces. CMM verified.
AS9100D Docs
Inspection reports and traceability for landing gear program records.
Aerospace Command Center of the Midwest
Chicago is Boeing's global headquarters city with deep aerospace roots — Collins Aerospace maintains major avionics and landing gear operations in nearby Rockford, Ducommun machines aerostructures across the metro, and a dense network of Tier 2 suppliers feeds Midwest engine and airframe programs. O'Hare's massive MRO ecosystem adds steady aftermarket demand.
RivCut serves Chicago-area aerospace suppliers with AS9100-quality machining, full material traceability, and the fast turns your Boeing or Collins program timelines demand.

Safety critical6 Fittings. 10 Days. Zero Concessions.
A Chicago-area landing gear team needed trunnion fittings from 300M steel with tight bore concentricity, cadmium plating prep, and full dimensional verification. Teams near companies like Boeing Global HQ trust this kind of precision and documentation rigor.
Every part shipped with complete documentation:
- CMM dimensional report — bore concentricity and true position verified
- Material cert with heat lot and AMS 6417 compliance
- First Article Inspection per AS9102
- Pre-plate surface preparation verification
What Chicago Aerospace Buyers Should Know
Verify your supplier can process Boeing D6-54551 quality clauses
Chicago-area subcontracts frequently flow down Boeing-specific requirements.
Ask for material certifications with full heat/lot traceability
Collins Aerospace Rockford rejects parts without AMS-spec certs on delivery.
Check that your shop can meet AS9100 document retention requirements
Midwest primes audit sub-tier records going back 7-10 years.
When Your Local Shop Can't Keep Up
When a prime surges volume, local shops push you back in the queue. We give you fixed lead times, instant quoting, and aerospace-grade documentation — every time. Chicago's aerospace sector demands it.
Documentation-Ready
Dimensional reports, material certs, and process records ship with every order — no chasing paperwork after delivery.
Full Material Traceability
Every bar ships with mill certs and heat lot numbers. Full chain of custody from raw stock to finished part.
CMM Inspection, Every Part
NIST-traceable CMM verification on every critical dimension before anything ships. No sampling — we inspect every part.
5–7 Day Prototype Turnaround
Most first articles ship in under a week. Rush available for simpler geometries. Confirmed ship date at order.
