Contamination and Aging Task Group
Define Deliverables

• 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
