Description

Review the module material, and respond to the following question using the written format included in the instructions and support pages.

Writing Prompt 

Read the two NTSB accident reports. 

Write a paper discussing the possible similarities of error chains and how the dynamics of SMS may have prevented these accidents.

CRITICAL ANALYSIS- ERROR CHAINS AND SMS
Critical Analysis- Error Chains and SMS
The two aviation accidents that occurred in New Mexico and Alaska present notable
similarities. The helicopters were conducting search and rescue missions when the unfortunate
accidents occurred. A significant cause of the accidents was poor weather conditions that had the
crews of both helicopters notified of the imminent danger. The accidents were preventable had
the pilots adhered to the warnings and the weather alerts issued, rendering the flights a risk. The
pilots could have accommodated safety program measures by identifying the hazard and
correcting it to prevent an accident (Sumwalt, 2013). While the purpose of the flights did not
necessarily entail many passengers or crew members, it was undoubtedly a risky event and an
unsafe act that the pilots needed to exercise caution to avoid. Weather is the major cause of the
two accidents as it seems to be a notable factor that significantly contributed to the crash.
However, some underlying factors existed that had weather conditions eventually causing the
crashes. The crashes comprise an error chain, which in the aviation safety context and SMS, is a
sequence of errors, either mechanical or managerial, that are overlooked and eventually become
hazardous, causing an accident (International Civil Aviation Organization, 2013). A link in the
error chain could have been removed to prevent the crashes, especially pilot error and issues
regarding organizational influence and unsafe acts.
The 2009 New Mexico aviation accident was due to an error chain that could have been a
warning signal to the organization to terminate the mission immediately. The report links the
accident to a terrain impact due to visual flight rules, resulting in a fatal injury (Nat...
