Why are some accident recurring?
In our aviation culture we are great at Analyzing Failure. Our focus seems to be on “What happened.” Even with this great emphasis on Failure Analysis, we still see the recurrence of similar accidents. The question is why! I recently participated in a discussion on the Aviation Safety Group. The discussion brought up several reasons for the recurrence of some accidents. Here they are:
- No resources to complete the job. Once a cause or causes have been identified, upper management does not support the efforts to implement the action necessary to eliminate or mitigate the causes. It seems that all Safety related issues can be traced back to upper management. Dr. W. Edwards Deming would not even work with a company in improving it’s quality unless the CEO on down were actively supporting the system.
- Investigation team with no experience. I always push the idea that Root Cause Analysis, RCA, teams must be “multidisciplinary.” In addition, there must be some experience members that have participated in other RCA sessions. No all the members of the team need to be experience but, there should be some facilitators that can lead the progress of the RCA.
- Solutions do not reduce the risk in fact. This occurs when the RCA team goes in the wrong direction. It is important to utilize tools for Root Cause Analysis that take away the “type A” personality and gives each member of the team equal say. I have found that these tools are readily available and I recommend a booklet: “SMS Memory Jogger II” published by GOAL/QPC. There are many tools found in this book that will accomplish the equitable results of a RCA. (SMS Memory Jogger II can be found at dtitraining.com)

4. Failure on management recommendations. Remember that the person who knows the most about a job is the person that actually does it. Management can recommend but, the recommendation must be analyzed and in most cases a risk assessment done to see if the recommendation itself does not add to the risk.
5. The root causes are not identified. Of course this is the most popular answer as to why accidents recur. It is important to follow the procedures for a standard RCA tool. First we must know the tools and how to use them. If we do not address the real Root Cause(s), the problem will recur.
