Methodology
1. Annual Accident Assessment
IBAC contracts annually to Robert Breiling and Associates to assess and collate business avia-tion accidents. The Breiling Report provides IBAC with operating hours for each aircraft type as well as accident statistics by aircraft type, by operator type and by area of the world. IBAC uses the information to publish a summary report in the annual Business Aviation Safety Brief.
To date the Brief has provided only limited information on accident by operator type due to the lack of acceptable exposure data in terms of hours of operation for each operator type.
It has always been recognized that achieving safety improvement is highly reliant on the knowl-edge base and understanding of the operations of greater risk so that mitigation can be deter-mined and applied. As an indicator applied to assessing risk, business aviation places impor-tance on statistical comparisons of the accident rate between the different business aviation op-erational types, namely accident rates for operations of corporate aviation, on-demand commer-cial and owner operated. Given the difficulty in obtaining exposure data for the hours attributed to each operational type, in the past it has been difficult to obtain with any degree of confidence the accident rates for each operation. However, with recent changes in the methodology and accuracy of an annual survey of general aviation and on-demand Part 135 operators by the US Federal Aviation Administration, IBAC has now concluded that data developed from the Survey is sufficiently accurate to serve as a methodology to provide a global perspective of the differ-ence in rates between the operator types.
