Notes

2011 data are preliminary.
Flight hours, miles, and departures are compiled by the Federal Aviation Administration.
Since March 20, 1997, aircraft with 10 or more seats used in scheduled passenger service have been operated under 14 CFR 121.
Years followed by the symbol * are those in which an illegal act was responsible for an occurrence in this category. These acts, such as suicide, sabotage and terrorism are included in the totals for accidents and fatalities but are excluded for the purpose of accident rate computation.Table 12 contains a list of illegal act occurrences involving US air carriers for the period covered by this table.
Based on a February 2002 FAA legal interpretation provided to the NTSB, any 14 CFR 135 operation conducted with no revenue passengers aboard will be considered an on-demand flight operation.This interpretation will be applied to accidents beginning with the year 2002.It has not been retroactively applied to 36 accidents, nine of them fatal that occurred during the period 1983 - 2001.
U.S. air carriers operating under 14 CFR Part 135 were previously referred to as Scheduled and Nonscheduled Services. Current tables now refer to these same air carries as Commuter Operations and On-Demand Operations, respectively, in order to be consistent with definitions in14 CFR 119.3 and terminology used in 14 CFR 135.1. On-Demand Part 135 operations encompass charters, air taxis, air tours, or medicalservices (when a patient is on board).
