Aging/Contamination Task Group Status • Discussed Contamination Survey Results • Age of Airplane? Original intent was general survey to validate types of contamination to implement some controlled tested. • Results are believed to align with Aging Wiring task group results. Will contact Aging Wiring group for data samples will be and photos of in-service locations of areas that accumulate dust/lint. Determine if testing was done with various levels of dust/lint/contamination. • Revise survey form to be specific about locations. Consider a web-based survey form. Align this survey with request for general in-service blanket samples across the fleet. These blankets will define the as-is condition of blankets; contamination level, thermal/analytical testing, and flammability properties. Results will be compared to lab tests on various levels of contamination types.
Aging/Contamination Task Group Status • Contamination Survey Results (continued) • Generally agreed with the priority of contamination types; dust/lint, CIC's, and fluids. CIC's will be easiest to start some controlled tests on different products. Boeing & Airbus will define the list of CIC's and that have been used and define a proposed test plan to run some tests. Airlines will define what CIC products that have used. • Dick Hill discussed some specific incidents that had very specific fire fuel sources; isopropyl alcohol, etc… illustrating that fluids and the processes used by airlines will be difficult to define common items. • Airlines will initially identify the common cleaning solvents that are used during maintenance.
Aging/Contamination Task Group Status • Contamination Survey Results (continued) • In the future need to look at other types of “contamination” such as insecticides and disinfectants (SARs). • “Quickest Completed Action Item Award” • Before the working meeting was over! Peter Short, BAB
Aging/Contamination Task Group Status • Discussed In-service Blanket Sample Collection • Agreed to have OEMs define very specific locations, Airlines identify heavy maintenance schedules 2 – 3 months in the future, so replacements blankets can be fabricated. • Breif Discussion on next material/part types to evaluate • from an aging/contamination effect. • Align with Hidden Materials task group. • Determine if a “data driven” approach can be used by reviewing in-service events and fire event participators.
Aging/Contamination Task Group Status • Aging: • Aging of PET films; review data with Evan Chu (Lamart) • for discussion with Eli Peirce. • Film Production and Usage Timeline
