Fuel Drains - Beechcraft Baron G58 Pilot Operating Handbook

Section 8
Handling, Serv & Maint
Caution must be taken when the wet wing
tip tanks are filled with fuel. DO NOT open
the outboard wing leading edge filler cap,
as fuel will exit from that opening. If this
occurs, wash the fuel from the wing surface
to prevent possible paint damage.
Ground the airplane with a static line before refueling and
secure the filler caps immediately after filling. Before letting the
airplane stand for several days, it is a good practice to fill the
wing fuel system to ensure that the cell inner liners do not dry
out and crack, allowing fuel to diffuse through the cell walls.
Also, less moisture condensation will occur when fuel cells are
full. If the cells are to be drained before storage, a coating of
light engine oil should be sprayed or flushed onto the inner lin-
ers of the cells as a preservative.
The 200 gallon fuel system should be filled
from the wing leading edge filler cap when
airplane must stand for several days.
Check and fill to capacity at wet wing tip
filler cap before flight if required for the mis-
sion.
The fuel fillers are equipped with spring-loaded anti-syphon
valves which may restrict large fuel nozzles. Push the valve
plate down carefully to fully insert filler nozzle.

FUEL DRAINS

Open each of the snap-type fuel drains daily to purge any
water from the system. The two sump drains extend through
the bottom of each wing. The fuel strainer in each wheel well is
provided with a drain extending through the wheel well skin.
Two additional flush-type fuel drains are located at the mid-
8-16
