UP разпрати оборотно писмо във връзка с използвани материали в някои модели крила. На някои крила (изброените модели ще намерите по-долу) за C и D линия са използвани Liros DC върви, които променят дължината си, свиват се при излагане на големи температурни разлики. Ето защо UP осигуряват подмяна на старите върви с нови от Aramidе.
Намаляването на дължината на C и D линията може да доведе до различно поведение при излитане на крилото, а също така до по-малка трим скорост и при по-големи изменения на дължината (разбирай скъсяване) до по-лесен срив.
Официалния дистрибутор на UP в България е Милен Дончев – www.4pilotsonly.com, свържете се с него за повече информация по въпроса.
Излагането на крилото на слънце не е добре за промазката на плата а също така и за конците, с които е шито крилото пишат още UP.
Следва оригиналното писмо на UP.
Safety Notice regarding certain paragliders built by UP International GmbH
The following models and series are affected:
UP Pico XXXS – Non-certified
UP Pico XXS – Non-certified
UP Pico XS, DHV certification number GS-01-1743-08
UP Pico S, DHV certification number GS-01-1737-08
UP Pico M, DHV certification number GS-01-1744-08
UP Pico L, DHV certification number GS-01-1761-08
Note that only wings from the so-called revision 1 are affected by this safety notice – these may be identified through their serial numbers, for instance Pico M: XA45M-01-… The number marked in bold reveals the revision number, and Picos marked with 02 are NOT affected by this safety notice.
UP Summit XC S, DHV certification number GS-01-1734-08
UP Summit XC SM, DHV certification number GS-01-1733-08
UP Summit XC M, DHV certification number GS-01-1735-08
UP Summit XC L, DHV certification number GS-01-1736-08
Note that only wings from the so-called revision 1 are affected by this safety notice – these may be identified through their serial numbers, for instance Summit XC M: XA45M-01-… The number marked in bold reveals the revision number, and Summit XC’s marked with 02 are NOT affected by this safety notice.
UP Trango 3 XS – Non-certified
UP Trango 3 S, DHV certification number GS-01-1632-07
UP Trango 3 SM, DHV certification number GS-01-1633-07
UP Trango 3 M, DHV certification number GS-01-1603-07
UP Trango 3 L, DHV certification number GS-01-1634-07
UP Trango 3 XL – Non-certified
The abovementioned wings use Dyneema lines, known as Liros DC series lines, from the first bifurcation up. In certain cases this has resulted in gliders having changed their launch and flight characteristics, as the C’s and D’s have shrunk while the A’s and B’s have maintained their length. The changes have in most cases been subtle (somewhat more sluggish launching and a slightly lower trim speed) but there have also been cases where the changes have been more profound. Our research into the most noticeable cases has shown that gliders exposed to extreme temperatures (like leaving a wing open on hot surfaces/very hot launches, etc.) are most likely to have changed, especially if the glider been flown at a low load (small sizes). It is worth noting here that not only lines suffer from high temperatures, all thermoplastics (including the glider cloth and the thread used to sew wings together) disagree with high temperatures.
For this reason UP International is publishing the following safety notice:
UP International GmbH recommends all owners of paragliders from the affected production series’ (see above) to have their middle and upper Liros DC lines replaced with lines made from Aramide. Owners are supplied with free replacement linesets and are recommended to get in touch with their local UP distributor for the replacement line set.
Please note that there is every chance that there is absolutely nothing wrong with your wing – we just want to be on the safe side! If you have felt no changes in behaviour, if your wing is still launching and flying fine, then don’t panic!
