he GA Accident Scorecard is produced by the Air Safety Institute to provide a broad view of GA safety performance and trends. The GA Scorecard precedes ASI’s Joseph

T. Nall Report, which provides much deeper analysis of GA accidents, trends and causes. The Nall Report relies heavily on NTSB accident investigations, which can take up to two years to complete for fatal accidents. The GA Scorecard is produced to provide an earlier view of GA performance to include total numbers of GA accidents, and the GA accident rate viewed in total and broken into several broad categories of GA activity. Each year, the GA Scorecard provides an initial look at the most recently completed year (2017 in this issue), and then completes the data for the initial look that was provided in the preceding year (2016 in this issue).

The news across GA is once again encouraging. For the third straight year, the overall GA fatal accident rate declined. Initial data from 2017 indicates that 2017 will reveal a fourth straight year. GA is benefiting from the combined impact of more activity and fewer numbers of fatal accidents, producing a substantial reduction in the overall fatal accident rate. Such overall performance indicates the constant work by all in the GA industry to drive safety initiatives is producing results in preserving aircraft and saving lives.

There is so much more we can do…must do to drive the GA accident rates even lower. Every fraction of a point improvement in the accident rate represents lives saved. ASI joins others in the GA industry in relentless pursuit of enhancing training, proficiency, equipment and the GA culture to continue these inspiring results.
