About the NASA ASRS Program


The ASRS is an important facet of the continuing effort by government, industry, and individuals to maintain and improve aviation safety. The ASRS collects voluntarily submitted aviation safety incident/situation reports from pilots, controllers, and others.


The ASRS collects, analyzes, and responds to voluntarily submitted aviation safety incident reports in order to lessen the likelihood of aviation accidents.


ASRS data are used to:


• Identify deficiencies and discrepancies in the National Aviation System (NAS) so that these can be remedied by appropriate authorities.


• Support policy formulation and planning for, and improvements to, the NAS.


• Strengthen the foundation of aviation human factors safety research. This is particularly important since it is generally conceded that over two-thirds of all aviation accidents and incidents have their roots in human performance errors.
