2. Contamination and Aging Task Group Risk Matrix - Ray Cherry

3. Contamination and Aging Task Group Task ; Obtain contamination survey information * Airline surveys * Benefit from EWIS Wiring Surveys Task ; Summarize survey information * Provide to Operations/Maintenance working groups * MSG3/Zonal information Task ; Down select “contamination” types and test * Perform flammability testing and analysis Task ; Collecting precursor event data Information & activities required from other organizations; * Obtaining MSG3 Zonal Analysis for specific airplanes * Electrical equipment locations & risk of ignition potential

4. Hidden Areas Contamination and Aging Task Group I. Risk Assessment and impact (probability) on overall airplane safety Age of aircraft. Accumulation over-time? Size - impact of fire based on aging II. Recommendations on contaminate types and test method Known contaminates (CIC, pesticides, etc.) and recommendations on use (hydrocarbons) Standard material test method for contaminated in-service blankets III. Recommendations for Contamination Mitigation Type of aircraft / age of aircraft Location / Zonal / Targeted IV. Recommendations for Material Selection Test for contaminate resistance Location specific Type of film / Film thickness Address known issues with materials (e.g.. non-shrinking materials) - Polyimide film - Ceramic papers - Foams (open vs. closed cell) - Susceptibility to aging V. Future technology recommendations for hidden areas Risk assessment based for further technologies Arc fault, detection, suppression, new fire resistant materials, etc… Define Deliverables
