Thermal Acoustic Insulation Contamination Research

This report summarizes the research work carried out on behalf of Transport Canada and the UK Civil Aviation Authority into the potential threat that might exist from contaminated thermal acoustic insulation materials). The research has been conducted in the light of related activities carried out by the industry which are also described or referenced in this report. The study is based on data analysis, literature searches, aircraft surveys, consultation with the industry, and flammability testing carried out on a test rig developed especially for this study.
This report addresses the nature of contaminants found on thermal acoustic insulation on in-service airplanes, the potential fire threat that they might present, and the actions taken by the industry to mitigate these threats. The report also makes ten recommendations aimed at improving the resistance of the airplane to hidden fires that might be fueled by contaminants.
