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.
4.2 Accident categories—Aerial work—Aeroplanes
As mentioned above, aerial work involves specialised operations such as fire fighting,
agricultural operations and aerial observation.

24 ANNUAL SAFETY REVIEW 2007
There is a particular problem in obtaining data related to accidents in aerial work.
One of the most hazardous types of operation in this regard is related to fire fighting.
However, in some States, this activity is carried out by State organisations
(e.g. the Air Force) and consequently the related activities are not classified as
aerial work but as “State flights” and consequently related accidents were not included
in this review.

The high number fatal accidents related to low altitude operations (LALT) is no
surprise as the nature of aerial work frequently involves operations close to the
ground, e.g. agricultural operations. Operating at low altitudes makes recovery
from a loss of control or an unforeseen event more difficult. The high number of
accidents assigned the category “unknown” is testimony that the investigation and
reporting of such accidents can be improved.

4.3 Business aviation—Aeroplanes
Under the ICAO definitions, business aviation is a subset of general aviation.
Data on business aviation are presented separately in light of the importance of
this sector.

The number of fatal accidents in business aviation for aircraft registered in EASA
MS is low. Nevertheless, it would appear that worldwide the number of fatal accidents
has been increasing in recent years.

26 ANNUAL SAFETY REVIEW 2007
Data on light aircraft accidents was requested from EASA MS in January 2008.
By the middle of April 2008, most States had supplied the information. Data were
missing from the Czech Republic, Ireland, Austria and Romania.
Reporting by States is uneven. Some provided data for accidents to parachutists,
para-motors and hang-gliders, others did not. Some used a mass limit of 454 kg
(1 000 pounds) to delineate “microlight” aircraft from “normal” aeroplanes, others
did not. Data from some States showed that for the same aircraft manufacturer
and model, two different classifications for the aircraft category were used. It would
appear that more work is required to harmonise these definitions.
Table 4 provides the number of accidents and their related fatalities for the years
2006 and 2007 based on the data reported.
