Such harnesses may not be used for flying anymore if their delivery dates back to more than 4 years. The following products by Finsterwalder & Charly are equipped with chest strap buckles of this type, which is why we issue a safety notice for all of the following products:ĭHV GS-03-0293-04 (not affected if equipped with SIL (Safe-In-Lock)!)ĭHV GS-03-0290-03 (not affected if equipped with SIL (Safe-In-Lock)!)ĭHV GS-03-0289-03 (not affected if equipped with SIL (Safe-In-Lock)!)ĭHV GS-03-0234-01 (not affected if equipped with SIL (Safe-In-Lock)!)ĭHV GS-03-0229-00 (not affected if equipped with SIL (Safe-In-Lock)!)įinsterwalder & Charly limits the service life of CLICK-LOCK and T-LOCK buckles to 4 years when they are used in paraglider chest straps. Safety notice: Harnesses equipped with Finsterwalder CLICK-LOCK and T-LOCK buckles In the following, you can find the safety notices for our harnesses an for the CL and TL buckles: The manufacturers were informed accordingly by the DHV. Afterwards, pulling out the plug by force was no longer possible. In the meantime, the DHV has reworked the SAT harness whose buckle could be opened by force according to our instruction and in the presence of Turnpoint. Please note: The manufacturers of the affected harnesses can provide for airworthiness within the stated period only if reworking was done by themselves or by an authorized third party. For reworking, the plug heads are clamped vertically aligned in a vise (see picture: reworking in the vise) and filed according to the rework instruction using a half round file. The harness manufacturers are responsible for the authorization and control of the rework service workshops. Woody Valley and Advance made this suggestion. Harnesses with expired service lives can temporarily continued to be used when a webbing loop is installed as a provisional backup security. The respective harness manufacturers will provide this information in their safety notices. How long the service life of inspected and reworked buckles can be extended depends on whether they are used in chest or in leg straps. The processing time currently takes 4-8 days but might become longer. We can only start reworking after we have received the original signed order. As a goodwill gesture, we offer the service free of charge for our Charly harnesses. This price includes VAT, the reworking and return shipping costs within Germany. Usually, we charge 38,- € for the service. Please print the order form and enclose it in the package with the harness or the chest strap plugs that are to be reworked. In any case, we need a signed order from the harness owner. At the moment, we rework only Charly harnesses and Advance harnesses from Germany. We can only rework other manufacturers' buckles if a maufacturer authorizes us to do so and if we accept his order. Hang glider harness manufacturers have the possibility to rework their harnesses' CL and TL plugs and therewith extended the buckles' service life from 10 years to a maximum of 20 years in total. We therefore limit the service life to 10 years also for this application. However, wearout after a longer time of use might lead to failure here, too. When the buckles are used in paraglider- and hang glider leg straps, they are subject to such dynamic loads only during takeoff and landing. Our later developed P-LOCK buckles do not have this disadvantage. In the case of heavy wear, the plug can be pulled out by force. When a plug is worn out, the buckle's closure might gradually be pushed open against the spring pressure of its lock buttons. They are, however, not optimally designed for this kind of stress and the effects of wearout play a role. The reason is that CL and TL buckles installed in paraglider chest straps are under permanent load and subject to frequent diagonal load changes. Due to the latest insights on their use in paraglider chest straps, we had to limit their permissible service life for this kind of application. Update on the safety notice about CLICK-LOCK and T-LOCK buckles in paraglider and hang glider harnessesĪfter having informed 43 paraglider harness manufacturers about how to rework their grounded harnesses, we would like to to give you an update on the status quo.ĬL and TL buckles have been developed 30 years ago.
