1 GA JSC SAT and Working Group Processes GA JSC SAT and Working Group Processes Corey Stephens Co-Chair, GA JSC SAT GA JSC SAT Meeting March 22, 2011 Washington, DC

2 GA Joint Steering Committee Evolve GA JSC to a CAST like Model – Voluntary commitments – Consensus decision-making – Data driven risk management – Implementation-focused The GA JSC is a means to… Focus Limited Government/Industry Resources on Data Driven Risks and Solutions

3 What is CAST? Work began in 1997 after two significant accidents in 1996 (TWA 800 & ValueJet 592) CAST focus was set by: – White House Commission on Aviation Safety – The National Civil Aviation Review Commission (NCARC) Opportunity for industry and government to focus resources on one primary aviation safety initiative

4 What is CAST? Vision Key aviation stakeholders acting cooperatively to lead the world-wide aviation community to the highest levels of global commercial aviation safety by focusing on the right things. Mission Enable a continuous improvement framework built on monitoring the effectiveness of implemented actions and modifying actions to achieve the goal. Goal Reduce the US commercial aviation fatal accident rate 80% by 2007 and Maintain a continuous reduction in fatality risk in US and International commercial aviation beyond 2007.

5 CAST Safety Strategy Influence Safety Enhancements - Worldwide Data Analysis Set Safety Priorities Achieve consensus on priorities Integrate into existing work and distribute Implement Safety Enhancements - U.S. Agree on problems and interventions How CAST Works

13 GA JSC Working Group Process Step 1: Analysis

14 Typical CAST JSAT Membership ALPA/APA FAA (AIR, AFS, ASA, AAI, ATO) Airbus EASA ATA Transport Canada NASA Engine companies – (PW, GE, RR-Allison) Boeing RAA NACA AIA NATCA

15 5.5-24 GA JSC WG Process Charter Development Establish Team Select Data Set Review Data Identify Intervention Strategies Assign Standard Problem Statements Record Characteristics/ Indicators Develop Event Sequence Evaluate Intervention Effectiveness Prioritize Interventions Technical Review & Report Results Identify Problems (what/why) Global Review of Characteristics/ Indicators Evaluate Problem Importance

16 Developed Event Sequence Facts and data Pilot - controller voice events Missed calls Events that occurred or should have Time coded each event

17 Develop Problem Statements Problem statements –What went wrong –Deficiency definition –Potential reason –Something which happened or didn’t happen

18 Sample Standard Problem Statements CAST Examples 10 FLIGHTCREW – Failure of flight crew to follow established procedures (SOP) 39 AIRCRAFT EQUIPMENT – DESIGN NOT ERROR TOLERANT System design does not provide adequate redundancy to counteract errors or alerting of the effects of errors 44 FLIGHTCREW – Flight crew failure to recognize and correct unstable approach 100 REGULATORS – INSUFFICIENT AIR CARRIER OVERSIGHT. Insufficient regulatory oversight of air carrier operations including management and training practices

19 Identify Intervention Strategies Intervention strategies –Suggested solutions –Things to do to prevent or mitigate the problem –Etc.

20 Intervention Effectiveness Power – Effectiveness of a specific intervention in reducing the likelihood that a specific accident would have occurred (“Perfect World”) Confidence – Confidence that this specific intervention will have the desired effect Future Global Applicability – How well the intervention can be extrapolated to apply to a world- wide fleet in the future

21 Effectiveness Rating Scales POWER This scale is to be used to judge the effectiveness of a specific intervention in reducing the likelihood that a specific accident would have occurred had the intervention been in place and operating as intended. (“perfect world”) Hardly any effect Slightly effective Moderately effective Quite effective Highly effective CONFIDENCE This scale is to be used to define the level of confidence that you have that this specific intervention will have the desired effect. Hardly any confidence Slightly confident Moderately confident Quite confident Highly confident 01 2 3 4 5 6 Not at all effective Completely effective 01 2 3 4 5 6 Not at all confident Completely confident FUTURE GLOBAL APPLICABILITY This scale is to be used to estimate how well the intervention can be extrapolated to apply to a world-wide fleet in the future. (for example: how often the situation it addresses occurs in accident scenarios; whether its impact is on present and future operations (equippage, traffic, regulatory differences); and whether it is applicable across airlines/airplanes/regions. Hardly any applicable Slightly applicable Moderately applicable Quite applicable Highly applicable 01 2 3 4 5 6 Not at all applicable Completely applicable

22 GA JSC Working Group Process Step 2: Implementation

23 GA JSC Feasibility Scales Technical Financial Operational Schedule Regulatory Sociological

24 GA JSC Safety Enhancements Develop Safety Enhancements from Interventions Collect detailed resource information Prepare Detailed Implementation Plans (DIP’s)

25 GA JSC WG Reports Standard Problem Statements Interventions Prioritized Recommendations Detailed Implementation Plans (DIPs)

26 What’s a DIP?

27 GA JSC SAT (Safety Analysis Team) Process Safety Plan Development

28 Develops a Prioritization Methodology (GA JSC SAT) Identifies the most effective solutions derived from all accident categories Considers effectiveness vs. resources Tests solutions against fatal and hull loss accidents Creates draft master strategic safety plan Identifies areas for future study/mitigation

29 Effectiveness that an intervention has for reducing the accident rate if incorporated Portion of world fleet with intervention implemented (),  Accident Risk Reduction = General Methodology for Calculating the Potential Benefit of a Safety Enhancing Intervention

30 Spreadsheet Example – Historical Airplane Accidents & Proposed Safety Enhancements – CAST Example

31 Basics of the Selection Spreadsheet Effectiveness Each safety enhancements is evaluated against each undesired condition in the set to determine how effective the enhancement would be at eliminating these conditions if the enhancement were put in place. Implementation Implementation level is based on the portion of the affected population with the enhancement incorporated or predicted to be incorporated by a future date. Severity Weighting To account for differences in severity or significance of the undesired conditions, a weighting value can be entered so that the relative risk of the undesired conditions is realized.

32 To account for differences in fatality risk associated with each accident in the data set, a severity value was applied. In this assessment, the severity value represented the portion of people onboard that perished in the given accident. Example: Comparison of two fatal accidents 757 CFIT accident, 98% perished. Weighting factor is.98 747 Turbulence accident,.6% perished. Weighting factor is.006 Hypothetically assume an assessment showed that the chance of these accident occurring would have been reduced by proposed safety enhancements by 50%. The associated portion of fatality risk eliminated can be determined using the severity weighting factor as follows: 757 CFIT.98 x.5 =.49 747 Turbulence,.006 x.5 =.003 Severity Weighting Overview CAST Example

33 Analysis Tool Output The spreadsheet output can be set up to show the effect that an individual safety enhancement, or group of safety enhancements have on reducing exposure to the undesired condition.The spreadsheet output can be set up to show the effect that an individual safety enhancement, or group of safety enhancements have on reducing exposure to the undesired condition.
