Airworthiness advisory Tow release freeX Control DHV 06-0027-98

SubjectTow release freeX Control DHV 06-0027-98

During a towing seminar it was recognised that the gluing of the cotter pin (stainless steel tube) on the Bowden cable could free itself as a result of faulty production batch and this can lead to the tow - release becoming jammed.

In agreement with the manufacturer freeX Airsports GmbH, Harmating 2, D-82544 Egling, Tel: 0049 (0) 8176 9302-0, Fax: 0049 (0) 8176 9302-044, Internet:, email:, the DHV has decided on the following precautionary safety measures: 

  1. All tow - releases of the type "freeX Control" must undergo a check of the gluing of the cotter pin. It is to be determined by a load test of 15kg if the cotter pin comes loose from the Bowden cable. Furthermore it is to be determined if the cotter pin aligns with the plastic sheathing of the wire releaserope. Both checks can be carried out by the pilot, or the tow - release can be sent to the company freeX Airsports GmbH who will carry out the check free of charge.
  2. If the cotter pin comes loose from the Bowden cable or the distance between the cotter pin and the plastic sheathing is greater than 1mm then the tow - release must be returned to freeX Airsports GmbH where it will be repaired free of charge.

This airworthiness instruction comes into force when it is published in the News for Paragliders and Hang Gliders (NfGH). The precautionary safety measure must be carried out before the equipment is flown again.
