Narrative:
During #2 engine change I was assisting on the connection of the thermal anti-ice (tai) ducting for the engine anti ice valve where the tool in question was used. After completion of the duct install I picked up tool and started to return to the floor when I saw that the thumbnail fairing needed installation. I then set the tool down on the wing to help with the fairing install. After installing the fairing I returned to the floor leaving the tool on the wing. The prybar was resting on a black stripe marking the border for the emergency exit pathway partially concealing it from view. The tool was subsequently discovered by a passenger on taxi to the runway.
