Narrative:

To perform the lube of the aft trunnion pins; I cleared person X to lower the flaps. Person X was in the cockpit and I was on the ramp. Remembering the flaps were cleared and fully extended a short time prior during the flap inspection for the MV2; I failed to look and double check that the area was safe for the flaps to be extended. As person X lowered the flaps; I walked to the right wing to continue with the lube card. 2 minutes later person X approaches me and informs me the flaps were lowered onto the golf cart which was located beneath the left wing. The flap had a 2x1 inch delamination on the inboard trailing edge corner. A temporary repair was performed and logged in a non-routine with a permanent repair required within 150 flight hours.
