The DNAA Master List was developed to support the following objectives: 1. Identify a set of fields that are common across airlines supporting ASAP programs 2. Enable an airline to share ASAP reports through the DNAA. The DNAA The DNAA database is composed of ASAP event reports that have been reviewed and closed by airline ASAP managers and made available in a de-identified format to a dedicated server that resides on the airline premises. The information contained within these reports includes demographic fields, event types and contributing factors, as well as, a full narrative description of the event provided by the reporting pilot. January 2005 through October 2006 marked the first phase of development of the DNAA and the successful demonstration of the establishment of the archive as a national resource for sharing pilot reported ASAP events across the commercial aviation industry. During this first phase of development, the fundamental hardware, software and networking structure that supports the DNAA was developed, implemented and demonstrated to the industry. The DNAA network currently includes participation of 8 airlines and as of September 2006, the DNAA will process airline data at a rate of approximately 650 ASAP event reports per month. Development of the DNAA Master List The establishment of the DNAA required the development of a common framework for enabling the review and assessment of ASAP reports across varying airline data collection formats and databases. This framework and a supporting industry standard taxonomy of ASAP demographic fields, event types and contributing factors was developed through the assessment of 16 ASAP programs. The ASAP taxonomy, referred to as the DNAA Master List is used to map each participating airline's ASAP categorizations and database structure to a common format. At the airline level, data residing in a pilot report is mapped to the DNAA Master List fields and reformatted to a common file format. This process enables the information provided by the airlines to be retained but standardizes the information across the industry.
The DNAA Master List Dictionary In the past, lack of clear definitions of domain concepts have lead to varying interpretations of common event types and contributing factors associated with aviation incidents. This is especially true when one considers that these concepts are categorized by multiple ASAP analysts with varying backgrounds and over several years. To expand the utility of the DNAA Master List the following objectives have been identified for the development of a DNAA Master List Dictionary:
