Narrative:

After departing refuel/dispatch base; dispatch contacted pilot of fuel smell after helicopter departure. Helicopter landed at home base 2 minutes later and the pilot found that the fuel cap had not been seated properly and the pressurized fuel was escaping. Ten gallons of fuel was lost during the repositioning. Aircraft was taken out of service while maintenance was contacted and pressure checked to verify that no seals were damaged during the venting. Don't become complacent with mundane operations. Carry adequate lighting to verify even simple tasks; especially if the current lighting at the refuel pads are not being maintained.
