Speed Tape
Speed tape is indeed used for running repairs but purely to prevent water ingress or to allow sealant cure beneath it.It has no structural integrity.Structural Repair Manuals tend to allow it for the above reasons but with strict limits to the damage allowed beneath and deadlines to repairing that damage.Not sure what they were using it for on that Airbus flap,maybe the Tech Log would tell us.......I'll get me coat
