| On a paraglider type Stereo from the
manufacturer freeX, several upper gallery lines broke during a commercial passenger flight
in Turkey. The paraglider was not flyable anymore, thanks to the rescue parachute nobody
got hurt.
After the investigation it turned out that the paraglider was strongly
used and several lines were pre- damaged. Furthermore the lines showed a huge number of
thickenings, up to spots where the line core material had come out of the line coat and
created loops. The breaking strength test showed a weakening of the concerned lines.
In agreement with the manufacturer freeX Air Sports GmbH the DHV has
decided on the following precautionary safety measure, according to § 14 LuftBO:
- The upper gallery lines of all paragliders of the types which include the following
letter-number combination in their serial number
