1. 1 International Helicopter Safety Team May 2007 1 Metrics: Are We Meeting the 80% Reduction Goals? 3 May 2007 AHS Forum 63 Roy Fox Chief, Flight Safety Bell Helicopter JHSAT

2. 2 International Helicopter Safety Team May 2007 2 International Helicopter Safety Team (IHST) IHST Goal settings & Worldwide Involvement JHSAT (Joint Helicopter Safety Analysis Team) Identify root causes and interventions –Accident data is regional driven Measure actual fleet effectiveness toward 80% reduction JHSIT (Joint Helicopter Safety Implementation Team) Develop Implementation approaches and implement interventions. Implementation is primarily regional controlled Measure implementation progress.

3. 3 International Helicopter Safety Team May 2007 3 JHSAT Dilemmas Intervention recommendations to be data & frequency driven. Different pockets of accident datasets exist around the world. Some Government reports are not released to the public, (military service, etc.). Accurate fleet flight hours are not available in most countries. Different operating rules, regulations and limitations. Implementation driven within a country regulations although some interventions may be done voluntary. Country stakeholders are part of the solution within their country. Must consider regional limitations.

4. 4 International Helicopter Safety Team May 2007 4 JHSAT Teams US JHSAT Lead Group: Assist regional JHSAT Teams Same analysis technique, format worksheet Using their regional accidents. JHSAT Regional Teams: –Their purpose is to identify root causes and interventions of their accidents so can be passed to their region’s JHSIT Team. US JHSAT Lead Team: Regional Teams’s Outputs used for JHSATs coordination worldwide. We learn from each other. JHSAT to measures IHST progress toward 80% reduction goals Worldwide By country By participation in IHST METRICS: Allow redirection of efforts. Refocus

5. 5 International Helicopter Safety Team May 2007 5 * Last year high “unknown” due to accident investigations still in progress. Likely to end up same % as previous years.

6. 6 International Helicopter Safety Team May 2007 6 Subject Fleet: Manufactured Helicopters Includes: –Civil certificated models (47, R22, 206B, S-76,etc.) –Military helicopter qualified for military but now flying on civil registries (Military Surplus) Not included: –Homebuilt (amateur) helicopters –Kit helicopters –Gyroplane/gyrocopters

7. 7 International Helicopter Safety Team May 2007 7 2016 Start Points ?

8. 8 International Helicopter Safety Team May 2007 8 Year 2000 Accident Slice (Known Minimum) Bell worldwide manufactured helicopter database using common accident definition. Databank being continually updated so situation is worse than shown.

9. 9 International Helicopter Safety Team May 2007 9 JHSAT Dataset Selection – Metrics A dataset must be consistent to have accurate results. Definition and process must be same throughout. Operations under common regulatory rules. 1. Basic US JHSAT dataset: NTSB: US Registered Helicopters –Regardless of country of occurrence (where crashed) –Gyrocopters and amateur kit built helicopter accidents removed –Foreign registered helicopters removed (counted against their country of registry) Accidents only per NTSB 830.2 definition (similar to ICAO). -Incidents are removed. 2. Regional JHSAT dataset: Use their official accident definition for their analyses. Use same dataset criteria as US JHSAT. 3. Worldwide Data/Metrics: US JHSAT worldwide database using same NTSB dataset criteria of US JHSAT.

10. 10 International Helicopter Safety Team May 2007 10 JHSAT Measuring Annual Progress 1.Accident rate/100,000 hr Worldwide and by Individual Country (and region) Compare rates and rate changes: IHST participants vs baseline non-participants Show IHST effectiveness in participant countries. Progress report to IHST each year Interim reports to Regional JHSAT/JHSITs.

11. 11 International Helicopter Safety Team May 2007 11 JHSAT Developing Accurate Flight Hours Track individual aircraft by serial number for flight hours HAI starting using same approach under FAA R&D to accumulate individual hours. Year start and end points calculated, flight hours rolled up to model series, then to major group segment. JHSAT developing flight hours for All civil registered helicopters worldwide.

12. 12 International Helicopter Safety Team May 2007 12 206B Flight Hours - 25 Years Registry Change

13. 13 International Helicopter Safety Team May 2007 13 Flight Hour Example from MMIR

14. 14 International Helicopter Safety Team May 2007 14 Sources of Flight Hour Data MMIRs (Maintenance Malfunction Incident Report – HAI) SDRs, AIDS (USA FAA) Accident Reports worldwide Anytime an individual aircraft total airframe time is known. (Maintenance, registry, Certification of Airworthiness, imported, exported, etc.) Internet, for sale postings, tradeshows, etc. Other sources Working toward “zero burden” on operator: Data mining airframe hours without asking operator.

15. 15 International Helicopter Safety Team May 2007 15 UK CAA has detailed flight hours in website Registry (last 3 years) ICAO starting similar with 4 countries. Will be involving ICAO/CAA into IHST and they can provide flight hours inputs. Need JHSIT assistance of all involved countries

16. 16 International Helicopter Safety Team May 2007 16 Flight Hour Exposure Process Homebuilts Kits Manufactured Helicopters Inactive (US ~ 24%) Active (flew at least 1 hour) Annual Flight Hours of Each Active Helicopter Aircraft Active Helicopter Fleet Flight Hours -Single Piston -Single Turbine -Multi Turbine For Each Helicopter Registered (Done for each country) JHSATs JHSITs

17. 17 International Helicopter Safety Team May 2007 17 Flight Hour Data Points & Registry For each civil registered helicopter, provide the following data point information for airframe flight hour points in time. 1.For a date in late 1999 or early 2000 (or prior to 1999) 2.For a date in late 2006 (or later) 3.For the date that the helicopter entered the country registry. 4.For the date that the helicopter left the country registry. A data point contains the following minimum elements: - Model - Registry Number - A/C Serial Number - Date - Total Time of Airframe Flight Hours (rounded to nearest whole hour) on that date.

18. 18 International Helicopter Safety Team May 2007 18 IHST Goal Starting Point Charter - IHST Goal States: “Reduce the helicopter accident rate by 80 percent by 2016.” US Goal for US Registered Helicopters: Average of 5 years prior to IHST initiation of Jan 2006. NTSB/FAA data on HAI website for 2001-2005 10,663,000 flight hours 974 accidents (Includes helicopters, kits, amateur homebuilts, gyroplanes) US IHST 10-year Goal Starting Point 2016 Goal Average Accident/ 100,000 flt hr9.11.83

19. 19 International Helicopter Safety Team May 2007 19 Worldwide Registered Helicopters Single Piston 40% Single Turbine 45% Multi-Turbine 15% Total Registered: 22,647 (2005 RosterRoster) Total Inactive? Unknown (Destroyed, Displays, Stored, etc.) Total Active? To Be Determined Active A/C Completion Status 1 May 07: 34% Present Registry Potential of 26,000+

20. 20 International Helicopter Safety Team May 2007 20 Worldwide IHST Goal - Set Later Lack of flight hours prevents establishing Goal Starting Point. JHSAT initiated effort in 2006 to determine accurate civil helicopter hours worldwide. Thus far, hours identified for 1/3 of potential fleet. Worldwide goal awaiting completion of flight hour effort underway.

21. 21 International Helicopter Safety Team May 2007 21 Worldwide*Accident Rates Est. After Flight Hours Done Anticipate Worldwide Rate Average to be 10-12/100,000 hr when done *No US DOD

22. 22 International Helicopter Safety Team May 2007 22 Worldwide Flight Hour Program Outputs Annual fleet flight hours to be accumulated into 3 groups within a country registry: –Single piston –Single turbine –Multiple turbine Regional flight hours will be furnished back to regional JHSAT/JHSITs to be used in determining intervention strategies and fleet safety improvements.

23. 23 International Helicopter Safety Team May 2007 23 Summary Data/implementation will be regional whereas analysis process is constant worldwide. Goal Metrics of participating countries & worldwide –Accident rate/100,000 hr Flight exposure information lacking worldwide JHSAT is developing country & worldwide flight hours –Single piston –Single turbine –Multiple turbine US Goal Starting & End Points Set: Reduce present accident rate per 100,000 flt hr of 9.1 to 1.8 by 2016
