Looks abit worrying, but if the FAA approve it then it can't be that bad...

I remember this stuff as far back as patching bulletholes in helicopter rotor blades. The trick there was you had to start at the trailing edge, wrap it around the leading edge and back to the trailing edge, covering both entry and exit holes. Then you had to put a piece of tape the same length - and therefore the same weight at the identical station on the opposite blade for balance purposes.
This was only a valid repair for honeycomb construction blades as they should lose no mass and weight when a bullet passes through them.

speed tape or 600 mph tape

its speed tape! alumium duct tape!

Hi 777, Buzz here. Funny, i was a about 10 or 12 when my Dad was flying SH-3A's
|Quoting Buzz (Reply 18):|
I recall that was called the "BIM Blade Indicator", it had black and white stripes if the pressure in the blade was good, all white if it had leaked. So if there was a crack in the blade, the pressure would leak down and somebody would notice before the blade came apart.

Could anyone explain what exactly is going on in this picture? Is this guy actually duct taping the covering of the engine pylon? Funny picture either way.

Gray tape known as "duct" tape is "pit" tape when you enter aviation. I still call it pit tape at home
|Quoting 777 (Reply 15):|
During one of those pre-check I remember that, looking at the join between the main rotor and each blade there was a sort of “pressure indicator” subject to accurate check by the pilot before each flight.
If I remember well (at that time I was only 10-12 years old), he told me that this indicator it’s so important to be checked because, in case of loss of internal pressure due to an hole (for instance), your blade will stall and you will crash… Now I’m quite sure that the blades of the Sea King are made with honeycomb construction, so I’m a bit confused…
Maybe the Sea King has a different system or maybe my memory it’s wrong… what’s your opinion?

I've heard duct tape (the regular, cloth, hardware-store variety) called a lot of things over the years... but never "pit tape". Interesting...

Pit Tape" is cargo PIT tape
