Aviation history is replete with lessons learned from
accidents. Aircraft accidents have greatly contributed to the formation of
aviation laws. Analysis conducted after accidents are the first steps taken for
the prevention of further accidents.
Accident
analyses are carried out by the countries' accident investigation board where
the accident happened or the one where the airline is registered. Several models are used in the analysis of accidents. One of these models, The Human Factors Analysis and
Classification System was put forward by Shappell and Wiegmann after examining more
than 2,000 accidents. This system is based on Reason's Swiss Cheese Model and,
therefore, also the Domino Theory. According to The Human Factors Analysis and
Classification System, the cause of accidents consists of 4 levels of factors
that affect each other. These are: organizational influences, unsafe
management, preconditions for unsafe acts and unsafe acts. Although an accident
may seem to be caused by unsafe acts, behind the accident there are many causes
extend from the managers to organizations. In this study, the databases of different
countries' accident investigation boards were studied and the official accident
reports of "planned and commercial" passenger flights were examined.
These reports were analyzed and coded according to the Human Factors Analysis
and Classification System. As a
result, the size and scope of the relationships between organizational
influences and unsafe acts that led to the accidents were revealed.
