The most common types of incidents involving general aviation aircraft in 2011 were largely airspace related (particularly airspace incursions and non-compliance with published procedures, information, or verbal ATC instructions, which were the most and second most common reported incidents). The top five was rounded out by wildlife strikes (animals and birds), reduced aircraft separation, and runway events (Table 27).
The significant reduction in miscellaneous airspace-related events over the last 10 years is a result of refinements in the classification of incidents by the ATSB.
