runway contact’), SCF-NP (‘non-powerplant
component failure’), RE (‘runway excursion’) and
RAMP (‘ground handling’). Accidents are
assigned under the runway excursion category
if during the accident the aircraft veered off
or overran the runway surface. In many cases
runway excursions are consequential events
in accidents and therefore a large number of
accidents are assigned this category. There has
been an increase in the rate of accidents
associated with ‘flight preparation, loading or
ground servicing’ (all categorised under
RAMP). Although this rate has increased to an
average of almost 8 accidents per 10 million
flights, it remains relatively low. ‘System
or component failures not associated with the
engines’ (SCF-NP), also appear to be ever more
present in accidents of EASA MS registered
aircraft. Accidents attributed as ‘controlled
flight into terrain’ (CFIT) appear to have an
overall decreasing rate.
3.2. Helicopters
The following section provides an overview
of accidents in commercial air transport
operations with helicopters (MTOM over
2 250 kg). Comprehensive operation data (e.g.
flying hours) was not available for this report.
In general, helicopter operations differ from
aeroplane operations. Helicopters often
operate close to terrain and take-off or land
in areas other than airports, such as helipads,
private landing sites and unprepared landing
sites. Also, a helicopter has different

aerodynamic and handling characteristics
from aeroplanes. All this is reflected in the
different accident characteristics.
3.2.1. F atal accidents
Figure 3-7 shows that between 1999 and
2008, 25 fatal accidents involving an EASA MS
registered helicopter occurred compared to
124 fatal accidents involving foreign registered
aircraft. As a proportion, EASA MS accidents
represent 17 % of the total. The number
of accidents varies over the decade. When
looking at the three-year moving average, it
appears that the number of fatal accidents
worldwide has increased in the second half of
the decade while the average for EASA MS
registered aircraft remained almost constant.
3.2.2. F atal accidents per
type of operation
Figure 3-8 presents the type of operation
involved in fatal accidents. When reviewing
the type of operation involved in fatal
accidents, a difference can be observed
between the EASA MS registered helicopters
and foreign registered helicopters.
When looking at foreign registered helicopters,
passenger transport is the main type of
operation involved in fatal accidents. Most
fatal accidents (14) of EASA MS aircraft involved
helicopter emergency medical services (HEMS).
This represents 42 % of the total number
of fatal accidents involving HEMS operations
worldwide. These HEMS flights facilitate
emergency medical assistance, where immediate
and rapid transportation of medical personnel,
medical supplies or injured persons is essential.
The ‘other’ category includes operations
such as cargo, commercial training flights
or operations the type of which is unknown.
It is worth noting that in the last decade,
worldwide 24 helicopters involved in fatal
