MAINTENANCE MANUAL
CAUTION: IF YOU CAN DRAIN THE FUEL FROM THE DRAIN VALVE AFTER YOU
_______ APPLIED HOT AIR TO THE EXTERIOR FOR 3 TO 5 MINUTES, DO NOT THINK THAT ALL THE ICE IS MELTED. THE ICE ADJACENT TO THE DRAIN VALVE UNIT CAN MELT AND LET SOME WATER AND FUEL FLOW FROM THE DRAIN. BUT, A PIECE OF ICE CAN STAY BEHIND. IF THE FUEL DOES NOT FLOW FROM THE DRAIN, CONTINUE TO APPLY HOT AIR FOR A SHORT TIME, AND FREQUENTLY DO A CHECK OF THE FLOW FROM THE DRAIN. CATCH THE FUEL IN A CONTAINER AND MAKE SURE ALL OF THE WATER IS REMOVED.
THE HEAT APPLIED TO THE SUMP DRAIN VALVES FOR THE OUTBOARD MAIN AND RESERVE THANKS WILL NOT REMOVE THE ICE WHICH HAS COLLECTED IN THE TANK SUMP OR IN THE DRAIN LINE BETWEEN THE TANK SUMP AND VALVE. TO REMOVE THIS ICE, YOU MUST PUT THE AIRPLANE IN A WARM HANGAR FOR SUFFICIENT TIME TO MELT THE ICE. THEN DRAIN THE SUMPS UNTIL THE WATER IS REMOVED.
(3)
In cold weather it is necessary to drain the fuel tank sumps prior to refueling to remove water from the fuel tanks if the airplane has been idle for more then 45 minutes prior to refueling. Drain the fuel tanks sumps again after refueling if the airplane has been idle for 2 hours or more after refueling, prior to departure (AMM 12-11-03/301).
(4)
When adding fuel, you must use these requirements:
(a) Make sure the fuel temperature is at least 6°F (3°C) above the fuel freeze point or -45.4°F (-43°C), whichever is higher. Use the ASTM method to determine the freeze point.
NOTE: The Fuel Quantity Indicator on the wing fuel station can
____ indicate slowly or not show numbers in extreme cold conditions. Use an external fuel flow meter to show the amount of fuel added to the airplane.
(b)
Use fuels that meet specification ASTM D1655; or
(c)
Use fuels that meet specification GOST 10227:
1) RT (PT, Russian spelling)
2) TS-1 (TC-1, Russian spelling)
