Goals and Objectives of SWAP

The System-Wide Accident Prevention (SWAP) project goal is to address aviation safety issues associated with human error and procedural noncompliance.

Human error is attributed as a factor in 60 to 80 percent of aviation accidents. Reducing or mitigating human error effects should result in significant aviation accident rate reductions.

SWAP consists of three sub-elements that emphasize human error mitigation research: (1) Human Error Modeling, (2) Maintenance Human Factors, and (3) Training. These sub-elements represent the highest priority topics identified in the ASIST process, as reported by the Human Error Consequences Subteam. This work breakdown structure (WBS) does not reflect all topics relevant to human factors, rather it identifies three broad domains that address human error prevention and mitigation. Although the focus during the ASIST process was on reduction of errors leading to catastophic accidents, SWAP also focuses on smaller errors, or chains of errors, that may lead to aviation incidents.
