MAS plane with duct tape on the wing

This week I flew from Kuala Lumpur to Phuket on Malaysian Airlines. I had a window seat by the wing and was a bit perturbed to see part of the wing was stuck together with 'duct tape'.

There were several layers of tape that looked like they had been there for some time.

I emailed a friend about it and he looked it up and found this article from askthepilot . It seems it is OK to use tape as a temporary measure, but I wonder how long it had been on this MAS plane.

The article says "What you’re actually seeing is a heavy-duty aluminum bonding tape known as “speed tape.” It’s a temporary fix and it’s used only on superficial or noncritical components, until more substantive repairs are made later on. The tape is extremely durable and is able to expand and contract through a wide range of temperatures. We never use, and don’t even stock, duct tape,” explains a veteran airline mechanic. “Some of the tapes we use cost hundreds, even thousands, of dollars per roll."

I just hope that MAS have used this "speed tape" and that it is just a temporary measure!!!!!!!
