Unsafe Condition
In case of a lightning strike, an ignition source can develop in the wing tank vapor space during fuel transfer from the center wing tank (CWT), if the electrical power for refueling is not switched off after refueling. Additionally, the cam on the access panel that operates the power switch can pivot away during closing, potentially leaving the switch in the 'ON' position.
