Fuel Drain Checks
The fuel drain checks should be done before starting each day’s flying.
Acrotank drain is located on the bottom side of the fuselage in front of the main spar.
Wing tank drains are located on the bottom side of the wing.
•
Use a clear container to extract fuel
•
Let it settle in the container before visually checking for signs of water or other contamination
•
Continue at each valve until free of water and / or contamination
After draining, ensure that each valve is closed and does not leak.
Leaking drain valves have to be replaced.
Refueling
Each tank has its own refueling point:
One on each wing, and one for the Acrotank, just forward of the windshield.
Use ignition key grip to open and close fuel caps.

ports and by opening the three drain valves.
