My approach involves using a combination of methods, often starting with a preliminary investigation to gather facts. This includes reviewing maintenance logs, examining damaged components, interviewing personnel involved, and analyzing any available flight data recorders (FDRs) or maintenance records.

I then apply techniques like the ‘5 Whys’ to drill down to the root cause. For example, if a helicopter experienced a hydraulic failure (symptom), asking ‘why’ repeatedly might reveal: 1. Why did the hydraulic line fail? (pressure surge). 2. Why was there a pressure surge? (faulty pressure relief valve). 3. Why did the pressure relief valve fail? (lack of preventative maintenance). 4. Why was preventative maintenance missed? (inadequate training of the mechanic). 5. Why was the mechanic inadequately trained? (lack of investment in training programs).

Finally, I document all findings in a comprehensive report, detailing the root cause(s), contributing factors, and recommended corrective actions, often including procedural changes and improved training programs. A crucial aspect is ensuring that the findings are reviewed by all relevant parties and implemented to prevent recurrence. I’ve successfully used this approach in several incidents, ranging from minor component failures to more significant events involving flight control systems, leading to substantial improvements in safety and maintenance practices.
