FAA WARNS ON AIRCRAFT DISINFECTION RISKS
December 11, 2020
On November 5, 2020, the FAA called to attention risks that disinfection products can have on aircraft interiors urging operators and maintainers to heed manufacturers’ guidance and take extra steps to protect sensitive equipment, wiring, and other high-risk components. According to the FAA, they acknowledge the Environmental Protection Agency’s publication regarding a list of disinfectants effective at inactivating COVID-19, but also note that they may not be suitable for aircraft, except in very limited and localized application.
Specifically, the agency’s area of concern: fogging and misting allows disinfectant to penetrate areas where it could create problems, such as underlying structure or fan-cooled electronics. The FAA recommends electrostatic spraying over fogging, because sprayers offer more directional control.
The FAA also advised increased inspections for corrosion in any areas where disinfectants are used. It notes that any procedure that creates pools of liquid should be avoided, as the “liquids can intrude into flight deck switches and seals…excessive liquid intrusion can lead to electrical shorts in the near term and unexpected corrosion in the long term.”
