For OEM Supply Chains · Supplier Risk
When a flight-critical part is sourced, the evaluation shifts from price to a rigorous supplier risk assessment — because a single nonconforming or late component can stop a line or ground an aircraft. Capacity, quality compliance, and financial stability outrank the quote.
The shift
On a consumer part, price is the deciding factor. On a flight-critical aerospace or defense component, it is one of the smallest. A multi-billion-dollar aircraft or weapons program can be held up by one bracket that arrives late, one housing that fails first-article, or one supplier that quietly runs out of capacity at the worst moment.
That is why aerospace OEMs have moved from comparing quotes to running formal supplier risk assessments. Procurement, quality, and program teams score a shop across capacity, compliance, and stability — and weight those dimensions far above unit price. The lowest bidder rarely wins; the lowest-risk supplier does.
The cost of getting it wrong
What gets scored
Different OEMs use different scorecards, but the questions converge on the same three areas. Each one asks, in effect: what happens to my program if this supplier is wrong?
01
“Can this shop deliver the full quantity, on schedule, run after run — and absorb a rate increase without dropping a beat?”
02
“Is the quality system real and audited — and is every nonconformance caught before it reaches the assembly line?”
03
“Will this supplier still be here — and still investing — three programs from now?”
The evidence
A risk assessment is only as good as the evidence behind it. Here is what an aerospace OEM evaluates in each dimension — and the verifiable capability we put against it.
| Dimension | What the OEM assesses | True Precision evidence |
|---|---|---|
| Capacity | Process breadth under one roof — fewer suppliers, fewer hand-offs, less risk. | 3- and 5-axis machining, CNC and Swiss turn-mill, wire EDM, and surface grinding in-house — up to 9-axis complexity. |
| Capacity | Sustained throughput and uptime across long production runs. | Lights-out machining with SensFlo AI spindle monitoring — predictive maintenance and condition-based scheduling, not run-to-failure. |
| Capacity | Ability to size to demand and scale on a rate increase. | Lean / Kanban / JIT production sized to actual demand, with capacity planning fed by per-machine OEE data. |
| Compliance | An audited aerospace quality management system. | AS9100 + ISO 9001 certified; ITAR registered; DFARS 252.225-7009 specialty-metals compliant; CMMC-compliant to NIST SP 800-171. |
| Compliance | Proof that every characteristic was verified, not sampled by eye. | AS9102 first-article inspection on ballooned prints, measured on a 2025 Hexagon Global S 7-10-7 CMM plus Keyence optical and 3D profiling. |
| Compliance | Full traceability and configuration control. | ProShop ERP/MES paperless traveler — material lot, heat number, supplier, and operator traceable on every part, FAI records linked to the lot. |
| Stability | Longevity through multiple aerospace cycles. | Privately held and family-owned, in continuous operation in Buellton, CA since 1998 — more than 25 years. |
| Stability | Evidence the shop reinvests rather than stagnates. | Steady reinvestment — a 2025 Hexagon CMM, ESPRIT 5-axis CAM with Vericut verification, Industry-4.0 machine monitoring, and a two-building, 17,000 sq.ft. facility. |
| Stability | Stable leadership and a skilled, retained team. | Owner-operated with 40+ years of hands-on industry leadership; grown from 5 to 30+ employees and held there. |

Why it de-risks your program
The point of a supplier risk assessment is to predict failure before it happens. The same controls that pass the assessment are the ones that protect your build rate, your schedule, and your airworthiness record once you are in production.
See the quality program →AS9102 first-article and 100% inspection of critical features on the Hexagon CMM keep nonconformances from escaping downstream.
SensFlo monitoring flags spindle and tool wear before it breaks — planned downtime instead of a stalled program.
ProShop ties every part to its material lot, heat number, operator, and FAI record — audit-ready traceability on demand.
ITAR registration and CMMC-compliant NIST SP 800-171 controls for secure handling of defense technical data.
DFM review is included on every quote — manufacturability and tolerance risk surface before a chip is made.
More than 25 years, owner-operated, continuously reinvesting — a supplier that will be there for the next program too.
