Airworthiness advisory  
Paraglider harness Airea System Tube DHV GS-03-0252-02 

Recently, problems have been reported in deploying an emergency reserve 
parachute from the tube-container of this harness. 
It is apparent that many reserve parachute inner bags prevent a correct 
emergency release, even though they may have passed a compatibility test. 

More details may be found here:

The tube container deployment problems were caused by the following:

The compatibility test for the emergency reserve parachute when combined 
with the tube container was inadequate. 
Through small changes to the correct configuration (e.g. by looping the 
deployment handle through a different attachment point to the inner bag) 
deployment may be made more difficult or in some cases impossible.
 
Increased frictional forces may be experienced during deployment when 
using inner bags which utilise a bag-chute to help opening. Bag-chutes 
(gauze/nylon construction combined with possible short line constructions), 
when mounted on the top or side of the inner bag create frictional problems 
and hence require greater deployment forces. 

In both cases a successful deployment may be hindered or made impossible 
in particular for example in an extreme spiral dive, when the induced 
g-forces are acting against the emergency parachute deployment direction. 

The force required for deployment may in such cases, 
exceed the testing criteria of 7 kg.
 
The DHV has issued the following safety advisory:

The Paraglider Harness Airea System Tube DHV GS-03-0252-02 may no longer 
be used with an emergency parachute mounted in the tube container.
An external container must be used in combination with this harness. 

This airworthiness advisory applies from the date of publishing in the 
News for Paragliders and Hang Gliders (NfGH).
 
The precautionary safety measures must be implemented 
before the equipment is flown again.

Lufttüchtigkeitsanweisung  
Gurtzeug für Gleitsegel Airea System Tube DHV GS-03-0252-02 

In der Vergangenheit traten wiederholt Probleme beim Auslösen von 
Rettungsgeräten aus dem Tube-Außencontainer des genannten 
Gleitschirm-Gurtzeugs auf.
 
Es hat sich erwiesen, dass die Kombinierbarkeit des Tube-Außencontainers 
dieses Gurtzeugs mit vielen Rettungsgeräte-Innencontainern 
problematisch und eine einwandfreie Auslösbarkeit auch nach erfolgter 
Kompatibilitätsprüfung nicht in jedem Fall gewährleistet ist.
 
Nähere Informationen hier.

Der DHV erlässt folgende Lufttüchtigkeitsanweisung:

Das Gleitschirm-Gurtzeug Airea System Tube, GS-03-0252-02, 
darf nicht mehr betrieben werden.

Ausgenommen davon ist der Betrieb mit einem extern angebrachten 
Rettungsgeräte-Außencontainer.

Die Lufttüchtigkeitsanweisung tritt mit Veröffentlichung in den NfGH in Kraft.
