# 1.0 Introduction
Business Aviation hasestablished a record asone oftheworld's safest forms oftransportation. Professionally flown aircraft of all sizes are operated on unscheduled routes to all corners of the globe, yetthe safety record continues to beexcellent inspite ofthevery challenging operatingenvironment. The exemplary safety record of business aviation can be attributed to professionalism and attention to safe operating practices. The business aviation community promotes safety through industry standards and good training, aswell asthrough monitoring and analysing safety information tofacilitate continuous improvement. The business aviation representative associations assist operators by providing safety data and programs in their respective countries. The Council representing the national and regional associations atthe global level, the International Business Aviation Council (IBAC), has in turn developed a program to collect and analyse worldwide information. To that end, IBAC has contracted with Robert Breiling and Associates todevelop global data on business aircraft accidents. Summary information presented in this Brief is taken from the analysis conducted by Robert Breiling and Associates in 2003. Breiling's detailed Report contains information on accidents from all regions oftheworld, including dataforeach aircrafttype. This Business Aviation Safety Briefcovers afiveyear period from 1998to 2002. IBACwill update the Brief annually and the IBAC Planning and Operations Committee (POC) and Flight Operations and SafetyWork Group will reviewthe information continuously to determine useful trend data. In addition, the IBAC Governing Board has determined that the Safety Briefwill b~ scrutinized from time totime by independent organizations and feedback will beconsidered by IBAC's POC andthe Briefwill beamended for Issue No.3 in2005. This summary data includes all accidents involving aircraft when used in conducting business operations. Itdoes not include accidents of business aircraft when used in airshows and other non-business related flying.

## 2.4 Organization of the Community Business Aircraft operations are classified intothree (3)separate categories: 1. Business Aviation Commercial Aircraft flown for business purposes by an operator having a commercial operating certificate (generally on-demand charters). 2. Corporate Non-commercial operations with professional crews employed toflythe aircraft. 3. Owner Operated Aircraft flown for business purposes bythe ownerofthe business. (Note: Consult IBAC for formal definitions ofthe three categories. Two additional classifications are included in the Breiling Report, namely Government (public operations) and Manufacturer aircraft. These are not, by their use, considered to be "business aircraft", butare included in the data for completeness.)

# 3.0 Business Aircraft Global Accident Data

(5 year period 1998 - 2002) 

## 3.1 Accidents by Operator Type A summary of the total accidents over five (5) years by type of operator is as follows:

Commercial 61 (54.5%) 20 (58.5%) 12.2 4.0 Corporate 24 (21.4%) 5 (14.7) 4.8 1.0 Owner Operated 17(15.2%) 7 (20.6%) 3.4 1.4 Government 4 (3.6%) 2 (5.9%) 0.8 0.4 Manufacturer 6 (5.4%) 0 1.2 0 Table 3.1a

Commercial 169 (57.6%) 57 (52.3%) 33.6 11.4 Corporate 25 (8.5%) 10 (9.2%) 5,0 2.0 Owner Operated 88 (30.0%) 38 (34.9%) 17.6 7.6 Government 10(3.4%) 4 (3.7%) 2.0 0.8 Manufacturer 1 (.03%) 0 0.2 0 Table 3.1b Analysis The majority of business aircraft accidents occur in the commercial category, where operations are governed by commercial regulations (such as FAA Part 135 and JAR OPS 1). The next most frequent number of accidents occurs with aircraft flown by business persons. Accidents of corporate aircraft remain rare.

### Analysis The trend over a period of 35years demonstrates asubstantive decrease inthe percentage of taxi accidents, and a notable decrease inaccidents inthe landing phase, although landing accidents remain asthe most prevalent. The trend indicates an increase in the number of accidents occurring in the approach phase. The percentage ofaccidents inthe climb phase hasalso increased substantively forturbo prop aircraft. The distribution ofaccidents inthe other phases has remained relatively unchanged. (Note: Supplementary data collected by Robert Breifing overa35 yearperiod was used to develop this trend.)

# 4.0 Global Accident Rate Data
4.1 Accident Rate byAircraft Type The accident rate per 100,000 flight hours for each year over a five year period, as well as for the total, is as follows:

Business Jets 0.55 0.16 0.62 0.18 0.43 0.17 0.58 0.20 0.50 0.10 0.53 0.16 Turboprops 1.40 0.62 1.62 0.46 1.72 0.61 1.29 0.49 1.31 0.55 1.47 0.53 All BusAle 0.98 0.40 1.12 0.32 1.06 0.38 0.92 0.34 0.88 0.31 0.99 0.35 Table 4.1a 

## 4.2Accident Rate by Operator Type Global data for the numbers of aircraft in each of the business aviation operational categories (commercial, corporate and owner-operated) proved difficult to obtain as few States collect this information. Similarly, flight hours by type of operation are not available. Due to the lack of good exposure data, itwas not possible to calculate, without some error, the rate of each category of operation. Additionally, the operational status of a single airframe may legally vary from flight to flight (Le., an aircraft may be commercial on one flight and private on a flight made later on the same day or vice versa). Nevertheless, by applying US data relevant to the division between categories of operator, and by making the assumption that the division is relatively similar for the rest of the world, an estimate of the rate by operator type can be made. Given that the North American data represents approximately 72% of the global total, it is unlikely that the distortion generated by the assumption will be very large. The percentage of flight hours for each of the three categories in the USA is as follows: Commercial (Air Taxi) Corporate Owner-operated Total 22.6% 38.3% 39.1% 100.0% (Averaged over 4 years)March 10.2004 Business Aviation Safety Brief

Assuming a similar division globally, the accident rates per 100,000 flight hours are as follows (based on data over 5years):

Commercial 9,248,590 230 77 2.48 0.83 (AirTaxi) Corporate 15,673,494 49 15 0.31 0.09 Owner-operated 16,000,878 109 45 0.68 0.28 All Business Aircraft 40,922,963 405 143 0.98 0.34 Table 4.2a Analysis The accident rates calculated in Table 4.2 include both turbo-prop and jet aircraft. The rate data indicates an excellent level of safety in corporate operations, whereas the accident rates in the commercial sector warrants increased attention by the business aviation community. 

## 4.3Accident Rate by Departures There is a growing trend for organizations reporting safety data to do so using accident rates per number of departures given that safety exposure is greatest during departure and arrival. Accidents of aircraft en-route are rare except for flights in low level flight in marginal visual conditions. Accident rates per departure, or flight segment or cycle, therefore provide more realistic safety correlations. The accident rate per 100,000 departures is as follows:

Large JetAircraft 3,046,816 13 3 0.42 0.09 Medium JetAircraft 4,536,569 27 9 0.60 0.20 Light Business Jets 7,760,927 72 22 0.93 0.28 All Business Jets 15,344,312 112 34 0.73 0.22 Table 4.3a Page 10 International Business Aviation Council (/BAC)Business Aviation SafetyBrief March 10,2004

Large Turbo Prop 627,459 54 22 8.61 3.50 Medium Turbo Prop 12,313,651 223 80 1.81 0.65 Light Turbo Prop 587,830 16 2.72

### If an assumption is made that the distribution of departures for operator types of commercial (22.6%), corporate (38.3%) and owner-operated (39.1%) is relatively the same asthe distribution between flight hours, the accident rates bytype ofoperation can becalculated asfollows:

Commercial 6,337,396 230 77 3.62 1.21 (Air Taxi) Corporate 10,739,923 49 15 0.45 0.13 Owner-operated 10,964,256 109 45 0.99 0.41
All Business Aircraft 28,041,576 405 143 1.44 0.50 Table 4.3d

International Business Aviation Council (IBAC) Page 11March 10,2004 Business Aviation SafetyBrief



### If it isfurther assumed that the distribution between operator types is proportional forjets and turboprops, the accident rate for jet aircraft by operational category can be extrapolated as follows:

### OAO 0,08 Owner-operated 5,984,081 17 7 0,28 0,11 All JetAircraft 15,304,556 112 34 0,73 0,22 Table 4.3e 

### Analysis A number of assumptions have been made related tothe distribution of exposure data, and as a resultthe data should be usedwith some caution, Nevertheless, noother ratedata is known to exist forworldwide business aviation. The results ofthe extrapolation should be sufficiently accurate to provide a reasonable comparison with accident information from other aviation sectors. The accident rate data demonstrates that corporate aviation has an excellent safety record overthe years measured. The corporatejet accident rateof0.08 accidents per 100,000 departures compares favourably with the scheduled airline rateof0.112 for hull lossand/orfatal accidents per 100,000 departures ofjet aircraft over 60,000 Ibs and 0.241 for non-scheduled and all other operations ofjet aircraft over 60,000 Ibs (Source: Boeing - Statistical Summary of Commercial JetAirplane Accidents, Worldwide Operations 1959-2002). The rateforscheduled operations ofjet aircraft as published by ICAO has shown a steady decrease year over year with thefatal accident rateofscheduledjet airline operations in2002 being .081. The data inthis Briefdemonstrates that there is room for improvement inthe commercial business aviation sector.
