based on data obtained from ICAO.
In ICAO documents, the term ‘aerial work’ is defined as an aircraft
operation in which an aircraft is used for specialised services such as
agriculture, construction, photography, surveying, observation and
patrol, search and rescue, or aerial advertisement. ICAO defines as
‘general aviation’ all civil aviation operations other than scheduled
or non-scheduled air transport operations for remuneration or hire
or aerial work. For the decade 1999 – 2008, the distribution of fatal
accidents by type of operation is as shown below.

Table 4-1 provides an overview of the number
of accidents and fatal injuries since 1997. The
number of accidents in aerial work operations
is similar for aeroplanes and helicopters for
‘the decade 1997 – 2006. In general aviation the
small number of accidents involving helicopters
in comparison to aeroplanes is probably
a reflection of the relatively lower number
of helicopters used in this type of operation.

4.1. Accident categories — General
aviation — A eroplanes
It was observed that several accidents obtained
from ICAO had not been classified in terms
of the accident categories. Consequently, the
numbers presented provide a low estimate
of the frequency for all accident categories. All
data refer to the decade 1999 – 2008.
Figure 4-3 presents that for general
aviation aircraft worldwide and within
the EASA MS, LOC-I (‘loss of control in flight’) is
the leading accident category. The number of
CFIT (‘controlled flight into or towards terrain’)
occurrences worldwide is about half of that
of ‘loss of control in flight’, while for EASA MS
it is about one third. Technical issues appear to
play a much smaller role.
In general, the experience for general
aviation is similar to that of commercial air
transport operations in that CFIT and ‘loss of
control in flight’ are the leading categories
for fatal accidents.
