What is the purpose of a 5-Whys root cause analysis in maintenance coding?

• A. To iteratively ask why to identify root causes and prevent recurrence
• B. To document fuel consumption
• C. To assign blame
• D. To schedule daily tasks

Answer: (A)

The idea behind the 5-Whys approach is to keep asking why a problem occurred, repeatedly, until you reach the fundamental underlying cause. In maintenance coding, this helps ensure the recorded corrective action targets the real issue rather than just fixing a symptom, so the problem doesn’t come back and the equipment stays reliable. It supports clear, traceable reasoning in the maintenance log about what went wrong and why, guiding effective fixes and preventive measures. It isn’t about documenting fuel use, assigning blame, or planning daily tasks. Those activities have different purposes, whereas 5-Whys focuses on drilling down to the root cause to prevent recurrence.
