U.S. Air Carrier(a) Fatal Accidents by First Phase of Operation(b)
KEY: R = revised.
(a) Carriers operating under 14 CFR 121. Before Mar. 20, 1997, 14 CFR 121 applied only to aircraft with more than 30 seats or a maximum payload capacity of more than 7,500 pounds. Since Mar. 20, 1997, 14 CFR 121 includes aircraft with 10 or more seats that formerly operated under 14 CFR 135. This change makes it difficult to compare pre-1997 data with more recent data.
(b) NTSB changed its reporting of phase of accidents. Data after 2008 is reported by Defining Event associated phase of flight leading to the accident. Before 2008 data is reported by first phase of operation, the phase of flight where the problem leading to the accident first occurs.
(c) Cruise (in-flight) numbers for 2001 are unusually high because of the incidents occurring on September 11, 2001.
