Section 8 – Handling, Service, & Maintenance
• Caution •
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 Ice Protection 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
De-Icing Fluid Tank
Serials before G3 Wing: The ice protection fluid tank is serviced
through a filler cap located on the LH side of the fuselage, just forward
of the baggage door. The tank is drained by actuating the Drain Valve
on the lower LH side of fuselage skin, just forward of fluid tank.
Serials w/ G3 Wing: The ice protection fluid tank is serviced through a
filler cap located on the upper LH wing skin. The tank is drained by a
lock-open/lock-close drain valve, located on an access panel in the
lower LH wing skin.
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.
