Airworthiness advisory Paraglider harness Excalibur DHV GS-03-0233-01

SubjectParaglider harness Excalibur DHV GS-03-0233-01

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:

  1. 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.
  2. 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.

In agreement with Firebird International AG, the DHV has issued the following safety advisory:

The Paraglider Harness Excalibur DHV GS-03-0233-01 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.
