AAD fires

Recommended Posts

They seem to be a lot more common than one would think. Cypress' website says ' The first life saved by a CYPRES dates back to April of 1991. Since then, more than 4,000 lives have been saved!'. Vigil reports 329 saves so far. Not sure how many MARS has.

I have not personally witnessed an AAD fire, but I've talked to a few instructors who have.

I looked up what seems to be the topic of discussion, for anyone (like me) who isn't closely watching USPA board meetings:

Quote

Other meeting highlights include:

  • To improve reporting of non-fatal incidents, especially those involving students, the board instituted the following new Basic Safety Requirement: “On any student jump, the supervising instructor, or both instructors if a two-instructor jump, must submit a completed incident report to USPA within 48 hours if any automatic activation device was activated on the jump. No disciplinary action will result from this self-report.”

Ref: https://uspa.org/Information/News/uspa-board-meets-in-dallas

Edit for sarcastic comment:
Although the rule hardly seems to be a BASIC safety requirement at all. Seems to be an administrative / data collection / reporting / paperwork requirement. Fair enough if the USPA is curious about the stats. (Is it just put into the BSR's because few bother with doing other incident reports? Are incident reports supposed to be mandatory in the USPA?)
'Before your jump, make sure to have some reporting forms stuffed in your jumpsuit, to make sure you have a safe jump! '

According to their website, they have an estimated 4000 saves. Out of an estimated 123,000,000 jumps (as of 2016), that equals approx. 1 save every 37,750 jumps. Hardly a "Problem" like the BOD and the new Safety and Training director are saying. Now, to be fair, we don't know how many of those were on a tandem or a training jump but, I'd be willing to bet very few

I got a reply from Aitec today. According to their rep, they've shipped 4750 replacement cutters to the US since 2011. This includes all their dealers and the military. The person I contacted felt the vast majority of these went to the military. That wude make sense. I find it difficult to believe 678 (average) per yr have been fired by sport use.

Airtec will also replace cutters that have been cracked or damaged where the wires enter the cutter body.  They provide a reinforcing stick on protector along with the replacement cutter.  This could account for a reasonable number of replacement cutters as well.

In the last 10 years I’ve seen or been on the jump at big way events where at least 6 AAD activations have occurred because of low openings. In that time I know of at least 2 AFF students losing height awareness resulting in AAD activation whilst I was on the DZ. it does happen more often than reported.

I watched an AAD fire on a student AFF jump and I also witnessed one from the air while I was under canopy, watched a guy go by in free fall and he pitched his main the same instant the AAD fired. He claimed that he was not low and the AAD malfunctioned. Take it from me he was that low!

As a rigger, over about the last decade, I've packed at least four Cypres saves, one of them a student on a level 1 AFF (many years ago - I don't know the specifics, nor would I tell you what they were if I did know, so don't ask). Two of the others were the same fun jumper. I feel like there was a fifth, but I'm not positive I packed that one (I did the repack and cutter replacement afterwards), so I'm not including it in the count...
