If you have an Aerodyne canopy I urge you to be on the look out for this possible slider grommet damage.
This was discovered on my slider by inspection after I noticed a new small hole had developed in my slider after a jump. Looking closely at how the hole lined up nicely with a grommet at first I shook it off as material just getting stuck during deployment. Upon asking my rigger to take a closer look for good measure he looked at the plastic ring under the grommet and found it was not only cracked but easily pulled away from the grommet leaving a nice channel for a line or lines to get caught.
Needless to say I took my canopy out of service until getting the slider replaced.
The first picture shows what the cracks look like. With no pressure at all I was able to lift the plastic away from the grommet. The third picture with the line placed in the space shows how much room there is for potential bad juju. This did not happen, but easily could. The final image is the new slider and how that plastic ring should look, no gaps all the way around.
Please inspect your slider grommets for damage regularly, if you notice this damage consider it not airworthy and get it replaced!
