Narrative:

On aircraft X arrival walk around found signs of delamination to right wing outboard trailing edge aft flap lower skin at inboard corner. A line technician and a lead line technician performed a tap test and agreed that flap shows signs of delamination. This was confirmed by a line sheet metal technician with a tap test and found out of limits per [manual] and updated the log page with details. But after all this; a maintenance supervisor signs off this log just by saying flap appears to be previously repaired; and provided no evidence and/or documentation of previous repair. Not only that but the maintenance supervisor also failed to mention in the sign off which trailing edge flap was inspected; left wing or right wing; inboard or outboard?this [report] is filed to report an FAA violation. The review of the log shows a trailing edge flap and also a bearing placed on aog (aircraft on ground) since they were not in stock. A review of maintenance log history was also performed and showed no record of repair done to this right wing outboard trailing edge aft flap. So let's get this straight: a line technician; a line lead technician and a line sheet metal technician agreed that this flap is delaminated with [manual] reference; but a maintenance supervisor can just say; appears to be; and sign it off! Really? Is this how we do maintenance? The union steward was informed of this and is investigating.
