10.2.1 Fuel piping should be accessible, protected
from mechanical damage, be effectively secured against excessive movements
and vibration, and so routed that it does not pass through passenger,
cargo, or crew compartments. Flexible fuel pipes should have suitable
connexions, be resistant to salt, water, oil and vibration, be visible,
easily accessible and should not penetrate watertight bulkheads.
10.2.2 Fuel tank filling, vent and drain lines
should be of adequate size and terminate in a manner that will not
constitute a hazard.
10.2.3 Provision should be made for the management
and control of the fuel system from a position readily accessible
to the crew. Where gravity tanks are arranged, remote controlled shut-off
valves should be provided at the tank.
