safety advisory DHV - legs straps

leg straps where they pass through the seat board inside the seat of the harness need a periodic check for wear, particularly in the case of kevlar or carbon seat boards.

This issue occurance could possibly be reduced by using an edge strip of something less abrasive than carbon.

Possibly thin rubber or even propeller tape or "helicopter" tape (the tape that is used on the leading edges of props or helicopter blades). The weight gain would be negligable. What do you think Francis?

I think Francis would agree that, even if your seat board is wooden, the straps should be periodically checked anyway just to be sure.

Yes Martin, the dhv notice i posted refers to a particular sup air harness that was recalled and exactly that solution was applied by the manufacturer;

Again, yes absolutely; a periodic check on the condition of the straps inside the fold of the seat where that seat board fits is very wise. even a smooth plywood edge can rub a nylon webbing over extended use. Our aircraft components alll have a finite life and their condition needs periodic checking Edited March 23, 2008 by Guest

The 'fluffy' half of self adhesive velcro is good for this.

another good solution, anything that smooths the edges and reduces the abrasion.

Of course even after fitting these protective strips we still need to periodically check the condition of the leg straps inside the seat and ensure our rubbing strips are doing their job.
