EASA 2020-0160

AD requires replacement of certain cockpit and cabin evaporator filters with serviceable parts and prohibits installation/reinstallation of affected parts. Prompted by reports that during production cockpit and cabin evaporator filters were installed on some PC-24s that were not the proper parts for the affected configuration. If not corrected, this condition could degrade the fire retardant properties of the filters, possibly resulting in an increase in smoke in the cockpit/cabin in case of electrical heater over-temperature.
