rehmwa 2 #1 October 23, 2014 I know I can send my expired Cypres in for trade in. or someone will buy it. But is the cutter still good? Should I sell it separately? What's it worth? I have questions,,,,lots of questions ...

hackish 8 #2 October 23, 2014 I think if it's over the 12 year time limit then it's not airworthy. A number of guys buy expired cypres units to jump in unregulated countries. I think there is the discount program to get these units out of circulation. -Michael Quote Share this post Link to post Share on other sites

I think there is the discount program to get these units out of circulation. so something as simple as the cutter also expires in addition to the main unit.....well, that seems like overkill (or more overkill) thanks, hoping someone can confirm definitively rather than with "I think" - but I appreciate the info regardless ...

cs_troyk 0 #4 October 23, 2014 Is the propellant in the cutter subject to degradation? It is sealed, but could environmental factors compromise the seal? If so, what type of time frame are we looking at? http://www.cypres.cc/?option=com_content&view=article&id=304&Itemid=95&lang=en Quote Share this post Link to post Share on other sites
Deyan 31 #5 October 23, 2014 rehmwaI know I can send my expired Cypres in for trade in. or someone will buy it. But is the cutter still good? Should I sell it separately? What's it worth? I have questions,,,,lots of questions The Cypres cutter has a life time of 15 years. It must receive a check every 4 years in order to stay airworthy. The 15 years life time info comes from a factory tour I did in 2011. I can't find any written info about that, so you can consider that as a"rumor"! The answer on your other question you can check here: http://www.cypres.cc/index.php?option=com_content&view=article&id=153&Itemid=104&lang=en Based on that, I'd say it's worth 30 $"My belief is that once the doctor whacks you on the butt, all guarantees are off" Jerry Baumchen Quote Share this post Link to post Share on other sites
koppel 3 #6 October 24, 2014 Deyan The Cypres cutter has a life time of 15 years. "The Check of Safety and Reliability Would you like to know how old your cutter is? No problem. You will find a number on your cutter cable. Compare this number with our list, and it will provide you with the exact date of when your cutter was built. On Cutters produced before September 2000, the date of manufacture is engraved on the plug. All CYPRES cutters have a 14.5 year lifetime when properly maintained. Comprehensive technical checks with each maintenance, complying with the required intervals for maintenance and respect for the maximum lifetime of a device are crucial to ensure the correct function of each CYPRES component. http://www.cypres.cc/index.php?option=com_content&view=article&id=157&Itemid=109&lang=enI like my canopy... ...it lets me down.

pchapman 261 #7 October 24, 2014 It isn't just a rumour... but the information is pretty hard to find and they don't seem to advertise it much. Cutters are good to 14.5 years... but from its own manufacture date which might be older than the Cypres it is attached to. (I just looked at a my stock of expired Cypres 1's, and saw cutter dates of 4, 8, and 10 months older than the main units.) Pretty much only helps if someone local has a Cypres fire and you want to get them back in the air quicker and have a recently expired Cypres lying about. (Cypres 1 manual says nothing about 4 year checks on cutters separately, but the Cypres 2 manual does, but the attached document doesn't mention it. So one can argue about whether a 13 year old cutter than hasn't had a "12 year check" would be legal. I doubt few would worry until the actual 14.5 year point is hit.) In a quick google search I can't find where I got the Airtec document so I'll just attach it. Would be nice to have an original source to confirm. [Edit: Koppel obviously found another Airtec info source] Quote Share this post Link to post Share on other sites

erdnarob 1 #9 October 26, 2014 The question is : is the cutter still good at expiration ? I understand, does the cutter still able to fire...and cut... The answer is YES. AADs cutters contain an explosive charge just like any kind of ammunitions. As I wrote already on this forum, few years ago I have phoned a store selling everything for fishing and hunting. When I asked about the life of ammunitions, they told me that at a local riffle range, some members were still shooting with ammunitions made during WWII. It was more than 60+ years ago. I have personnaly fired several cutters from the two leading AADs makers, using a charged capacitance. To make it more obvious, I put a ripcord cable into the hole. They not only fired properly but they also cut the steel cable. Cutters with a tapered blade or a circular one do the same job. The cutters mentioned in the thread question were from early AAD models and were more than 15 years old (probably around 20 years old). See the picture of two types of the fired cutters.Learn from others mistakes, you will never live long enough to make them all. Quote Share this post Link to post Share on other sites
jurgencamps 0 #10 October 27, 2014 And, AIRTECH uses all those old and expired cutters for their demonstrations. I think that they have fired several thousand without failure. Quote Share this post Link to post Share on other sites
