b. Place a container under the fuel sump drain outlet, which is located under the fuselage.
c. Drain the fuel strainer by pressing down on the lever located on the right-hand side of the cabin
below the forward edge of the center seat. The fuel selector must be positioned in the following
sequence: off position, left tip, left main, right main, and right tip for PA-32-260 and 300, and off
position, left main and right main for PA-32R-300 and PA-32-300 (
S/N 32-7940001 and up ) while
draining the strainer to ensure that the fuel lines between each tank outlet and fuel strainer are
drained as well as the strainer. When the fuel tanks are full, it will take approximately 11 seconds to
drain all the fuel in one of the lines between a tip tank (PA-32-260 and 300 models only) and the
fuel strainer and approximately six seconds to drain all the fuel in one of the lines from a main tank
to the fuel strainer. When the fuel tanks are less than full, it will take a few seconds longer.
d. Examine the contents of the container placed under the fuel sump drain outlet for water and
sediment and dispose of the contents.
CAUTION: WHEN DRAINING ANY AMOUNT OF FUEL, CARE SHOULD BE TAKEN TO
ENSURE THAT NO FIRE HAZARD EXISTS BEFORE STARTING ENGINE.
NOTE: After using the underseat quick drain, it should be checked from outside to make sure it has
closed completely and is not leaking.
2-38. DRAINING FUEL SYSTEM.
Fuel may be drained from the system by opening the valve at the inboard end of each fuel tank. Push up
on the arms of the drain valve and turn counterclockwise to hold the drain in the open position. The flush
type drain valve requires the drain cup pin to hold valve open. The remaining fuel in the system may be
drained through the filter bowl. Any individual tank on a PA-32-260 and 300 or tank set on PA-32R-300
and those PA-32-300 with
S/N 32-7940001 and up , may be drained by closing the selector valve and
then draining as desired.
2-39. ANTI-ICING FUEL ADDITIVE. (Refer to the latest revision of Lycoming Service Letter No. L172.)
CAUTION: ASSURE THAT THE ADDITIVE IS DIRECTED INTO FLOWING FUEL STREAM.
THE ADDITIVE FLOW SHOULD START AFTER AND STOP BEFORE THE FUEL
FLOW. DO NOT PERMIT THE CONCENTRATED ADDITIVE TO COME IN
CONTACT WITH THE AIRCRAFT PAINTED SURFACES OR THE INTERIOR
SURFACES OF THE FUEL TANKS.
CAUTION: SOME FUELS HAVE ANTI-ICING ADDITIVES PREBLENDED IN THE FUEL AT THE
REFINERY, SO NO FURTHER BLENDING SHOULD BE PERFORMED.
CAUTION: THIS ADDITIVE SHOULD NOT BE USED AS A REPLACEMENT FOR PREFLIGHT
DRAINING OF THE FUEL SYSTEM DRAINS.
The operation of the aircraft is approved with an anti-icing additive in the fuel. When an anti-icing
additive is used it must meet the specification MIL-DTL-27686, must be uniformly blended with the fuel
while refueling, must not exceed 0.15% by volume of the refueled quantity, and, to ensure its
effectiveness, should be blended at not less than 0.10% by volume. One and one half liquid ozs. per ten
gallon of fuel would fall within this range. A blender supplied by the additive manufacturer should be
used. Except for the information contained in this section, the manufacturer’s mixing or blending
instructions should be carefully followed.
