The objective of this study was to assess the number of serious injuries and fatalities that might have been avoided by the use of 16-g dynamic seats during the period of 1984 to 1998 for survivable accidents involving transport category aircraft operating under 14 CFR Part 121. Twenty-five impact- related accidents involving aircraft operating to 14 CFR Part 121, or equivalent, were identified during the period from 1984 to 1998 that may have had seat-related fatal or serious injuries. Each of these accidents was analyzed in detail and a mathematical technique was used to model each accident scenario. Monte Carlo simulations were used to assess a high, median, and low value for the total achievable benefits over the period 1984 to 1998 to U.S. registered aircraft operating under 14 CFR Part 121. Two methodologies were used. The first was based on worldwide accident data for aircraft operating under 14 CFR Part 121 or equivalent. This analysis results in the following prediction of benefit: (1) Reduction in Fatalities = 51 with a 95 percentile range from 33 to 68; and (2) Reduction in Serious Injuries = 54 with a 95 percentile range from 28 to 79. The second analysis was carried out on the accident data pertaining to U.S. aircraft operating under 14 CFR Part 121 only. The analysis of this smaller data set has resulted in the following prediction of lives to be saved: (1) Reduction in Fatalities = 23 with a 95 percentile range from 12 to 40; and (2) Reduction in Serious Injuries = 18 with a 95 percentile range from - 1 to 32.
