We use both CAA and Aviation Safety Council (ASC) (2009)
investigation reports to classify the aviation occurrence categories
in accordance with the ICAO’s classification standard. Referring to
the definition of occurrences by the ICAO, the ASC investigates
aviation occurrences that involve fatality, injury, or substantial
damage to aircraft. Because there are few records of aviation
occurrences or accidents per ten thousand departures, we used the
CAA reports from 1985 to 1998 as well as the ASC reports from 1999
to 2011.1 The common taxonomy and definitions established by the
ICAO include six groups of incidents (Table 1). According to Aviation
Safety Council (2012), between 2002 and 2011 runway excursions
caused one accident and eight serious incidents; turbulence
encounter (TURB), four accidents, other two accidents and two
serious incidents; and fire/smoke (Non-Impact) (F-NI), one accident
and three serious incidents (Fig. 1). We focus on the accident,
serious incident, and fatal accident rates, respectively, as measures
of safety performance (Chang and Yeh, 2004) to build relationships
between aviation occurrence rates and AOC.
