What is the most common cause of mishaps according to analysis of mishap data?

• A. Inadequate training on equipment
• B. Lack of deliberate and systematic RM during preparation, planning, and execution of operations and activities.
• C. Poor weather conditions
• D. Equipment malfunctions due to wear

Answer: (B)

The main idea here is risk management. Analysis of mishap data shows that the most common root cause is the lack of deliberate and systematic risk management during preparation, planning, and execution of operations and activities. When hazards aren’t identified, evaluated, and mitigated as part of the normal workflow, small errors and unsafe conditions can compound, making a mishap much more likely. This highlights how processes and human factors—consistently applying hazard identification, risk assessment, and controls—often drive safety outcomes more than weather, equipment wear, or training alone.

Inadequate training can contribute, but even well-trained teams can encounter mishaps if risk management isn’t used. Weather and equipment issues can be factors, yet they are more often secondary to not applying a structured risk-management approach to the task at hand.
