Based on the 27 years of aviation data in Taiwan, we found that
the ICAO grouping categories e takeoff, landing, and ground
operation and aircraft, and the subcategories of icing, turbulence
encounter, and other most significantly affected aviation occurrences.
The subcategories, controlled flight into/toward terrain and
system/component failure or malfunction (non-power plant) most
significantly affected fatal accidents, and runway incursion-vehicle,
aircraft or person, ground collision most significantly affected
accidents. Runway excursion and ground collision were the top two
causes affecting serious incident rates.
