Paralock separation carabiner

Many features of separation carabiners offer increased safety, but a safety check is essential when attaching the risers.

In the past there have been several unintentional Paralock releases that have ended without serious consequences. Recently, however, there was a fatal accident during a tandem flight in Italy, yet no evidence of product failure has been found.

The German air sports association DHV has carried out investigations in this regard and concluded that the Paralock 3 can be used safely provided that the prescribed safety check is carried out when attaching the risers.
However, design improvements are required and planned to reduce future risks when using the Paralock.

The cause of some of the unintentional releases of the Paralock 3 was that the foot accelerator lines were wrapped around the release button and the swivel lever was opened when the accelerator was operated. Our instructions in a safety notice to use the Paralock 3 only in blocked mode, even in mono use, were not followed in two cases. We will offer a good retrofit solution to prevent wrappings in early 2025. Paralocks that have not been retrofitted can be safely operated with the swivel lever blocked.

The Paralock's swivel lever principle requires the user to apply counter-pressure to the release button when attaching the glider in order to check that it is securely engaged. The fact that the Paralock swivel lever engages automatically in the locking position is a temptation to use the karabiner carelessly, and it cannot be ruled out that, for example, jammed lines or webbing will prevent it from locking automatically. The safety check is therefore essential. The DHV investigation makes this clear.

Safety note Paralock 3 !

All users of the Paralock 3 are requested to carry out a functional check before the next flight. This is due to several unintentional openings in flight, which are probably due to incorrect operation. However, in order to rule out a malfunction, a check by the user is necessary. This consists of releasing the swivel lever at a deflection of about 45°. It should then lock automatically. Afterwards, correct locking must be checked by applying counter-pressure.
This function check must be carried out regularly. If the function check is negative, the Paralock must be returned to the manufacturer.

We would also like to point out that the safety instructions in the Paralock 3 operating instructions must be observed.
In particular, the secure engagement of the swivel lever must be checked immediately before each launch by pushing against the release button.

In addition, the Paralock 3 may only be flown with the additional blocking mechanism activated. This applies not only to tandem use, but also to mono use.

Furthermore, the pilot must not unblock the carabiner during flight (except after an emergency parachute deployment).

Safety Note Paralock 3

During the use of the Paralock 3 without the additional activation of the release blocking mechanism by means of the securing pin, it has happened that the risers have been released unintentionally. Loose hanging lines of the speed system wrapped around the release button in such a way that when the speed system was subsequently operated, the release lever was turned to the open position. The incident had no serious consequences.

RECOMMENDATION FOR EXCHANGE

Improved inner container for CHARLY reserves available. Also applies to KORTEL Krisis Karré und MAC PARA Houston.
An improved version of the Tom Grabner inner container is now available for all CHARLY Second Chance and DIAMONDcross rescue systems as well as for the KORTEL Krisis Karré and MAC PARA Houston reserves. As before, the new container has two separate compartments for the lines and the canopy, so that the canopy is only released after the lines have been stretched, minimising the risk of entanglements between the reserve and the glider. A new feature is that the canopy compartment is slotted, making deployment more reliable even with low airflow or sub-optimal packing. .... more info!

CHARLY TARGETcross

DIAMONDcross, the patented steerable cross canopy, has been newly revised and is now available again after the supply bottleneck with the waterproof light canopy. It is now supplied with an improved inner container, which not only offers a high level of security against entanglement in the paraglider, as before, but also releases the canopy even more reliably in low inflow conditions.

The CHARLY DIAMONDcross with the new container is now called CHARLY TARGETcross.

DIAMONDcross/ TARGETcross opening safety

Already during the development of the DIAMONDcross, the topic "entanglement of the rescue system with the main glider" was crucial for diverse product details, which have been certified with additional tests far above certification criteria during the summer.

The most dangerous situations for a rescue system becoming entangled with the main glider are SAT-like rotations after tangling up. ... more info!
