Introduction – To consider the following elements in focus:
- How to enhance the depth of our internal audits with focus on Root Cause Analysis Techniques.
- How to identify systemic risks before they become findings in an EASA audit,
- How to ensure that the Quality Control processes are compliant and effective.
Root Cause Analysis (RCA) vs. Symptom Analysis
A common EASA / CA finding is “Inadequate RCA.” If your internal audit findings end with “Retraining Provided” or “Staff Admonished,” you have failed to find the root cause.
- Essentially you have merely identified the person who was standing there when the system failed. You need to identify all root causes as well as all contributing factors.
Identifying Latent Conditions
You should be auditing the RCA process itself.
- Example – Ask: Does the Quality Manager have the authority to challenge a department head’s weak RCA? If the answer is no, your systemic risk is a lack of “Independence of Quality,” which is a high-level EASA concern.
Advanced Root Cause Analysis: Beyond the “Human Error” Trap
The primary reason RCA fails during EASA audits is that it stops at the individual.
- In a systemic audit, you must assume the technician intended to do the job correctly. If they didn’t, the system failed them.
Auditing the RCA Process Itself
Instead of just reviewing an RCA report, audit the logic chain used to create it.
Did the investigator look for Latent Conditions?
- Example ambiguous MOE procedures,
- Poor lighting
- Software Issues
The Contribution of “Context”
Evaluate the Environmental and Organizational Context.
- Was there a spike in workload that week?
- Was the technician subjected to fatigue?
- Important to account for RCA variables,
- Avoid corrective actions being assessed as “superficial”
Identifying Systemic Risks: The “Predictive” Audit
EASA is increasingly moving toward Risk-Based Oversight (RBO). To stay ahead, the internal audits must identify “Weak Signals”
- Small, repetitive issues that haven’t caused a failure yet but indicate a breakdown in the system.
The “Audit of the Audit” (Meta-Auditing)
Look at your previous six months of internal findings. If 80% of your findings are “Level 2” or “Minor,” and you have zero “Level 1” findings, you likely have a Detection Risk.
- This suggests your auditors are either too close to the production team or are focusing on “low-hanging fruit” rather than systemic vulnerabilities.
The Independence of Compliance Quality vs. Production Pressure
A systemic risk often overlooked is the Erosion of Standards due to production pressure.
- During your audit, interview the Certifying Staff & seek to identify a lack of “Just Culture” which may be a systemic risk that EASA will treat as a major non-compliance.
Ensuring QC is Compliant & Practically Efficient
Quality Control (QC) is the prerogative of the organisation under the management of the business area owner
- To bridge this gap, the audit must evaluate if the QC process is integrated or isolated.
- In EASA terms, a workaround is an unauthorized procedure.
- By auditing for efficiency, you are actually auditing for the root cause of future non-compliance.
