This paper examines factors that have influenced the average accident rate per million departures in Taiwan
from 1985 to 2011 involving turbojet aircraft hull loss. Our analysis is based on the nature of rare events,
used to find the importance of the International Civil Aviation Organization occurrence categories. The
most significant occurrences were in order of importance are: takeoff, landing, and ground operations;
aircraft; miscellaneous; weather; and airborne. The subcategory of runway incursiondvehicle, aircraft, or
person was the most significant effect for accidents; runway excursion for serious incidents; system/
component failure or malfunction in non-power plant; turbulence encounter for occurrences; and
controlled flight into or toward terrain for fatal accidents.
Between 2002 and 2011, the average accident rate per million
departures in Taiwan involving turbojet aircraft hull loss was 2.57
times the world’s average (Civil Aeronautics Administration (CAA)
(2012)); the average rate of hull loss occurrences on commercial
jets was 1.75 per million departures and on turboprop aircraft was
1.31. The International Civil Aviation Organization’s (ICAO) (2009)
safety targets include reduction in fatal airlines accidents, serious
incidents, runway excursion events and ground collision events and
here we look at the causes of these events and how they relate to
the safety targets set out in Taiwan’s Civil Aviation Administration’s
(2011) Sate Safety Program (SSP) using the fixed-wing aircraft
investigation reports of aviation accidents in which the aircraft
were registered in Taiwan. These accidents are classified according
to the International Civil Aviation Organization (2008) Aviation
Occurrence Categories (AOC). There were 55 aviation occurrences by
fixed-wing aircraft in Taiwan, where 32 were accidents, including
14 fatal, and 23 serious incidents.
