Abstract:

Due to the COVID-19 worldwide pandemic, aircraft owners and operators may find it necessary to more frequently and thoroughly disinfect airplanes. The increased use of disinfectants on aircraft materials leads to the possibility of material degradation or negative impacts on equipment. This report investigates and discusses the effects of more frequent disinfection on properties of the test articles. The researchers identified eight materials commonly found in flight decks as well as four line replaceable units (LRUs) for this study. Four commonly used disinfection methods were identified and utilized to condition the test articles: fogging, electrostatic spraying, wiping, and UV-C disinfecting. After conditioning was complete, the test articles were evaluated for changes in their tensile strength, flammability properties, physical properties, and material properties. It was determined that all of the chemical disinfectants evaluated caused changes in at least one material property in the plastic and coating coupons tested in this study. Likewise, LRUs also experienced changes from each chemical disinfectant. Certain display coating configurations passed eight years of UV-C exposure at 254 nm and 280 nm with no change to the measured material properties while other coating configurations experienced changes at only one year of UV-C exposure.
