National Aeronautics andSpace Administration Ames Research CenterMoffett Field, CA 94035-1000 TH: 262-7 MEMORANDUM FOR: Recipients of Aviation Safety Reporting System Data SUBJECT: Data Derived from ASRS Reports The attached material is furnished pursuant to a request for data from the NASA Aviation SafetyReporting System (ASRS). Recipients of this material are reminded when evaluating these dataof the following points. ASRS reports are submitted voluntarily. The existence in the ASRS database of reportsconcerning a specific topic cannot, therefore, be used to infer the prevalence of that problemwithin the National Airspace System. Information contained in reports submitted to ASRS may be amplified by further contact withthe individual who submitted them, but the information provided by the reporter is notinvestigated further. Such information represents the perspective of the specific individual who isdescribing their experience and perception of a safety related event. After preliminary processing, all ASRS reports are de-identified and the identity of the individualwho submitted the report is permanently eliminated. All ASRS report processing systems aredesigned to protect identifying information submitted by reporters; including names, companyaffiliations, and specific times of incident occurrence. After a report has been de-identified, anyverification of information submitted to ASRS would be limited. The National Aeronautics and Space Administration and its ASRS current contractor, BoozAllen Hamilton, specifically disclaim any responsibility for any interpretation which may bemade by others of any material or data furnished by NASA in response to queries of the ASRSdatabase and related materials. Becky L. Hooey, DirectorNASA Aviation Safety Reporting System CAVEAT REGARDING USE OF ASRS DATA Certain caveats apply to the use of ASRS data. All ASRS reports are voluntarily submitted, andthus cannot be considered a measured random sample of the full population of like events. Forexample, we receive several thousand altitude deviation reports each year. This number maycomprise over half of all the altitude deviations that occur, or it may be just a small fraction oftotal occurrences. Moreover,not all pilots,controllers,mechanics,flight attendants,dispatchers or otherparticipants in the aviation system are equally aware of the ASRS or may be equally willing toreport. Thus, the data can reflectreporting biases. These biases, which are not fully known ormeasurable, may influence ASRS information. A safety problem such as near midair collisions(NMACs) may appear to be more highly concentrated in area “A” than area “B” simply becausethe airmen who operate in area “A” are more aware of the ASRS program and more inclined toreport should an NMAC occur.Any type of subjective, voluntary reporting will have theselimitations related to quantitative statistical analysis. One thing that can be known from ASRS data is that the number of reports received concerningspecific event types represents thelower measureof the true number of such events that areoccurring. For example, if ASRS receives 881 reports of track deviations in 2010 (this number ispurely hypothetical), then it can be known with some certainty that at least 881 such events haveoccurred in 2010. With these statistical limitations in mind, we believe that thereal powerofASRSdata is the qualitative information contained in report narratives.The pilots,controllers, and others who report tell us about aviation safety incidents and situations in detail –explaining what happened, and more importantly,whyit happened. Using report narrativeseffectively requires an extra measure of study, but the knowledge derived is well worth the addedeffort.
