Narrative:
While working in l-hand wing, fuel spar area, I noticed loose safety wire on the #1 forward boost pump pressure transmitter line. If this transmitter works loose, fuel could leak into enclosed area of the inboard leading edge, possibly sticking a bleed air duct in area. Should be re-safetied.
