The Real Cost of Non-Certified Aerospace Parts: Compliance & Safety
In aerospace manufacturing and maintenance, there is little margin for error. Every component installed on an aircraft must meet strict regulatory, safety, and performance standards. Yet despite this reality, non-certified aerospace parts still find their way into supply chains—often driven by cost pressure, availability challenges, or schedule urgency.
While these parts may appear identical to certified alternatives, the hidden costs associated with non-certified aerospace parts can be substantial. These costs often surface later in the form of compliance failures, safety risks, operational disruptions, and long-term financial exposure.
Understanding Non-Certified Aerospace Parts
Non-certified aerospace parts are components that lack formal approval, documentation, or traceability required by aviation authorities and industry quality systems. This may include parts without FAA or EASA acceptance, incomplete material certifications, missing inspection records, or fabrication performed outside of AS9100-compliant processes.
The absence of certification does not always mean the part will immediately fail, but it does mean there is no verified assurance that it will perform reliably over time or under operational stress.
The efforts to mitigate the use of non-certified parts has a long history in the industry. According to an article in the Journal of Air Law and Commerce, for example:
“The aviation industry has been aggressively involved in resolving unapproved parts issues. Many air carriers, aircraft and parts manufacturers, and repair facilities have established internal unapproved parts programs. These programs include such aspects as enhanced receiving inspections, internal SUP reporting procedures, and increased supplier surveillance.”
Regulatory Exposure and Compliance Risk
The aerospace industry is governed by rigorous regulatory frameworks designed to ensure safety and airworthiness. The use of non-certified aerospace parts directly undermines these frameworks.
Regulatory consequences may include:
- Audit findings and corrective action requirements
- Delays in production or maintenance release
- Fines, penalties, or enforcement actions
- Aircraft grounding or program suspension
Even a single non-certified component can compromise an entire assembly or system, triggering extensive rework and documentation reviews.
Safety Implications of Non-Certified Aerospace Parts
Safety is the most critical concern associated with non-certified aerospace parts. Certified components are manufactured, tested, and inspected to withstand known operational loads, fatigue cycles, temperature extremes, and environmental conditions.
Unfortunately, while it is relatively rare, accidents have been linked to the use of non-certified parts. In fact, unapproved or non-certified aerospace parts (often called Suspected Unapproved Parts, or SUPs) have been linked to recent in-flight emergencies, mechanical failures, and historical accidents. Recent investigations, such as the 2023 AOG Technics scandal involving forged paperwork for engine parts, have highlighted the persistent risk these components pose to aviation safety.
Non-certified aerospace parts may:
- Use unverified or substituted materials
- Bypass controlled manufacturing processes
- Fail to meet dimensional or structural tolerances
- Exhibit unpredictable fatigue or wear behavior
When failures occur in flight-critical or mission-critical systems, the consequences can be severe, exposing organizations to significant liability and reputational harm.
Operational Disruptions and Costly Downtime
One of the most underestimated impacts of non-certified aerospace parts is operational disruption. When parts are flagged during inspections, audits, or in-service performance, the downstream effects are rarely minor.
Common operational consequences include:
- Unplanned maintenance events
- Production line stoppages
- Aircraft-on-ground (AOG) situations
- Emergency sourcing and expedited logistics
These disruptions often result in costs that far exceed the original savings gained by sourcing non-certified aerospace parts.
Loss of Traceability and Quality Control
Traceability is fundamental to aerospace quality management. Certified suppliers provide documented lineage from raw material through final inspection, enabling accountability and root-cause analysis when issues arise.
Non-certified aerospace parts frequently lack material heat and lot traceability, process control documentation, inspection and test records, and configuration and revision control. Without traceability, organizations lose visibility into their supply chain and weaken their ability to maintain consistent quality standards.
Impact on Customer Trust and Market Position
Aerospace customers expect strict adherence to certification requirements. The discovery of non-certified aerospace parts can seriously damage customer confidence and jeopardize long-standing relationships.
Potential business impacts include:
- Removal from approved supplier lists
- Disqualification from future programs
- Increased scrutiny during audits
- Loss of competitive standing
In an industry where trust is built over years and lost in moments, these risks cannot be ignored.
The Illusion of Cost Savings with Non-Certified Parts
At face value, non-certified aerospace parts may appear less expensive. However, this perceived savings often masks substantial long-term costs.
Hidden expenses commonly include these five issues:
- Scrap and rework
- Replacement with certified components
- Audit remediation efforts
- Legal and insurance exposure
- Lost revenue from delayed or canceled programs
When evaluated over the full lifecycle, non-certified aerospace parts almost always result in higher total cost of ownership.
The Value of Sourcing with Certified Aerospace Suppliers
Certified aerospace suppliers and fabricators operate within controlled quality systems designed to mitigate risk. They provide documentation, traceability, and process discipline that protect both the product and the customer.
Working with certified suppliers helps ensure:
- Regulatory compliance
- Consistent product quality
- Predictable lead times
- Reduced operational and legal risk
Certification is not an administrative burden, but a safeguard built into the aerospace ecosystem.
A Risk-Based Sourcing Perspective
In today’s aerospace environment, sourcing decisions must be evaluated through a risk-based lens. The question is no longer whether non-certified aerospace parts are cheaper upfront, but whether they expose the organization to unacceptable downstream risk.
For manufacturers, MROs, and operators alike, certified parts support long-term stability, safety, and program success.
