U.S.A. and Canadian Operators Accident Rates Hull Loss and/or Fatal accidents - Worldwide Commercial Jet Fleet through 2003 Accident rate (accidents per million departures) 2003 STATISTICAL SUMMARY, MAY 2004 Source: Commercial jet transport has achieved significant improvements in safety in four decades, and has maintained a very low accident rate. Commercial jet transport has achieved significant improvements in safety in four decades, and has maintained a very low accident rate. 1 accident Worldwide (0.4 US) per Million departures

Fire Safety Strategy Summary Similar to other accident causes, fire events were much more frequent in the early years of commercial jet aviation Similar to other accident causes, fire events were much more frequent in the early years of commercial jet aviation Many fire safety improvements have been adopted… cargo systems, seats, cabin materials, lavatories, insulation and so on Many fire safety improvements have been adopted… cargo systems, seats, cabin materials, lavatories, insulation and so on Fire accidents have been reduced to a very low rate Fire accidents have been reduced to a very low rate But today's fire safety strategy remains based on events from early in the history of jet transport But today's fire safety strategy remains based on events from early in the history of jet transport Proposed Strategic Focus Focus on the prevention of frequent ‘precursor’ events to enhance fire safety Focus on the prevention of frequent ‘precursor’ events to enhance fire safety

Olsen (FAA) In the U.S., our focus was set by the White House Commission on Aviation Safety

11 Copyright © 2004 Boeing. All rights reserved. The National Civic Aviation Review Commission (NCARC) on Aviation Safety Provided Additional Direction FAA and the aviation industry must develop a strategic plan to improve safety, with specific priorities based on objective, quantitative analysis of safety information and data Government should expand on their programs to improve aviation safety in other parts of the world Source: Safer Skies Briefing, 6/2003, K. Olsen (FAA)

CAST Goals l Reduce the U.S. commercial aviation fatal accident rate by 80% by 2007 l Work together with airlines, JAA, ICAO, IATA, FSF, IFALPA, other international organizations and appropriate regulatory/ government authorities to reduce worldwide commercial aviation fatal accident rate Dollars/Flt.

Conclusions and Recommendations Post-Crash Fuel-Fed Fire Post-Crash Fuel-Fed Fire  Fire Safety Industry adopt and accept the CAST Risk Reduction plan for accident prevention. Worldwide implementation through ICAO and others Worldwide implementation through ICAO and others In-Flight Hidden Fires In-Flight Hidden Fires  Fire Safety Industry Should Implement: Improved maintenance practices and methods - ATSRAC Improved maintenance practices and methods - ATSRAC Systems ‘over-current’ and ’over-heat’ protection (1) Systems ‘over-current’ and ’over-heat’ protection (1) Non-Essential Equipment standards enhancement Non-Essential Equipment standards enhancement Aftermarket (STC) equipment installation standards enhancement Aftermarket (STC) equipment installation standards enhancement Smart Circuit Breaker (arc fault/GFI) with fault ID servicing tools (1) Smart Circuit Breaker (arc fault/GFI) with fault ID servicing tools (1) Contamination/Aging – Materials and Maintenance Contamination/Aging – Materials and Maintenance  The UK AAIB advocates a similar approach:  Bulletin No: 6/2004, Dated 21 May (2) (2)Source:http://www.dft.gov.uk/stellent/groups/dft_avsafety/doc uments/page/dft_avsafety_ hcsp (1) Priority on non-critical systems
