Several breakings of red aerotow - lines distributed by Sunglide (Sybille Baeumer-Fischer), Schilcherhof, 87463 Dietmannsried, have been reported to the DHV -Tow office. One pilot got injured in the face.
Examinations revealed that the used line material has a maximum breaking strengh of only 140 daN, instead of the provided 200 daN minimum strength.
Under load, the sharp edged shackle and the knots can weaken the tow rope additionally, and result in a much lower breaking strength. (see foto).
The DHV warns all hangglider pilots to use this tow rope anymore.
