Section 8 – Handling, Service, & Maintenance
During long periods of non-use, the porous panel membranes
may dry out which could cause uneven fluid flow during
subsequent operation. Perform the Pre-Flight Inspection every
30 days to keep porous panel membranes wetted.
Use only approved deicing fluid. See Section 2, Limitations. To
prevent fluid contamination, maintain a clean, dedicated
measuring container and ensure mouth of fluid container is
clean before dispensing. Secure the filler cap immediately
after filling
Certain solvents may damage the panel membrane. Use only
soap and water, isopropyl alcohol, or ethyl alcohol to clean
panels. Do not wax leading edge porous panels.
Storage
To prepare the Anti-Ice System for flyable storage, fill the deicing fluid
tanks and perform the Pre-Flight Inspection to verify evidence of ice
protection fluid along the length of all porous panels. The tanks may
then be drained until the next service interval (30 days minimum) or
operation of the system is desired.
Servicing
Deicing Fluid Tanks
The deicing fluid tanks are serviced through filler caps in the upper
wing skins. Each tank is individually drained and vented by lock-open/
lock-close valves in the lower wing skins.
Porous Panels
Periodically clean porous panels with soap and water using a clean,
lint-free cloth. Isopropyl alcohol may be used to remove oil or grease.
