Publication of the Air Safety Institute’s annual Joseph T. Nall Report, which contains detailed analysis of a single year’s GA accidents, has been postponed while the National Transportation Safety Board completes its investigations of 2010’s fatal accidents. In the meantime, the Air Safety Institute has compiled a concise statistical summary of the GA accident record of 2010 and a preliminary tally of accidents in 2011. The report is available for download.

There were 1,160 accidents on noncommercial fixed-wing flights in 2010, a decrease of 21 from 2009, and 19 fewer fatal accidents (214, down from 233). Unlike most recent years, when decreasing numbers of accidents resulted chiefly from reduced flight activity, FAA estimates indicate that the number of hours flown actually increased by 3 percent. The estimated rate of 6.30 accidents per 100,000 flight hours was 4.5 percent lower than the previous year’s estimate of 6.60, but remained in line with the average of the past 10 years. The estimated fatal accident rate decreased by more than 10 percent, from 1.30 to 1.16 per 100,000 hours, one of the lowest on record.
