When SMS is directed from the bow.
Despite this, in 1926 and 1927 there were a total of 24 fatal commercial airline crashes, a further 16 in 1928, and 51 in 1929, which remains the worst year on record at an accident rate of about 1 for every 1,000,000 miles flown. Based on the current numbers flying, this would equate to over 7,000 fatal incidents per year. Aviation was not considered to be a safe mode of transportation.
SMS is to know what options to balance.
Air safety regulation as we know it today has been shaped by aircraft disasters that have happened in the past. Any given aviation disaster can be attributed to human failure, technical failure, extreme weather, or sabotage. Over time all these factors were as good as eliminated from aircraft accidents. Aviation had become the safest mode of transportation available. In search to further improve safety, the Safety Management System in aviation was implemented as a regulatory requirement to address human factors. Since all other systems had been improved, the time was right to improve the human factors system.
However, when the SMS was seen as the last link to create the utopia of safety in aviation it became the failure of aviation safety. SMS in itself could not and cannot fail, since it is a parallel system and an observing system of applied processes and not a system of operational control, but a system and tool to manage operational control. When applied correctly, SMS is the tool to discover flaws and apply corrections and not a tool to create the utopia of safety.
There are several articles written and surveys conducted placing a negative view of the Safety Management System. When SMS is looked upon as the one solution to bring utopia of safety into flying it will fail in the eyes of the beholder. In addition, if biased and personal opinions are applied, an effective SMS could easily be described as a disaster to safety. This is simply because an effective SMS describes and paints a picture of how safe the operations are and to what confidence level an operator can support safety by data. When these articles and surveys describe SMS as being un-safe, or not useful at all, their statements are describing the operations itself and not the SMS. SMS is a system analyzing personal behavior and it becomes easier to attack the messenger than accept the facts of personal behavior that SMS had already discovered. When SMS becomes personal it sets the stage for operational failure and not the failure of the SMS.
