What’s Wrong with This Component?

A Deep Dive into Failure Analysis and Why It Matters
By Fedor House LLC
Picture this: You’re walking through the plant floor. Everything seems fine - machines humming, lights blinking, production flowing. Then suddenly—bang! One machine goes down, a line halts, and a small component is to blame.
So, what happened? And more importantly… could it have been prevented?
Welcome to the world of Component Failure Analysis—the process that helps you move beyond simply replacing broken parts to truly understanding why they failed and how to stop it from happening again.
Why Failure Analysis Matters
Failure analysis isn't just for engineers in lab coats. It’s a foundational practice for anyone working in maintenance, operations, reliability, or quality control.
It’s the difference between reacting to failure and preventing it entirely.
Understanding component failure means:
Boosting equipment uptime
Improving product reliability
Minimizing costly downtime and safety risks
In short, it’s about creating a culture of intentional reliability, not just quick fixes.
The 4 Steps of Effective Failure Analysis
Here's how to approach failure analysis with confidence and precision:
1. Collect Historical Data
Don’t just look at what broke—look at the history.
When was it last replaced? What conditions was it exposed to? Vibration? Load? Temperature?
Use CMMS records, maintenance logs, and operator notes.
2. Conduct a Visual Inspection & Perform Testing
Now zoom in. Is the component cracked, corroded, misaligned, or sheared?
Use your five senses and tools like thermal imaging, ultrasonic testing, or vibration analysis.
3. Identify the Failure Mode
Was this a fatigue failure, a brittle fracture, fretting, thermal degradation, or contamination?
Match the failure with the forces and stresses it faced.
4. Implement CAPA (Corrective and Preventive Action)
Don’t stop at “replaced the part.”
Investigate root cause. Was the wrong fastener used? Could a Nord-Lock washer prevent vibration loosening?
Document lessons learned and finally, train your team.
Real-World Impact
We've seen small, overlooked parts lead to hours of downtime and cause thousands of dollars in lost production. Yet, we've also seen teams transform the situation by making intelligent adjustments that completely prevent future failures.
A client replaced a standard washer with a vibration-resistant locking washer (Nord-lock, Lock Washers - Grainger Industrial Supply) on a high-shock case packer. This straightforward adjustment completely resolved the recurring failure. Quick fixes are temporary, whereas addressing the root cause is transformational.
