A pilot reported that the seam of the webbed strap that connects the brake pulley to the riser tore during ground handling his Skywalk Mescal5. The seam may not be strong enough if it was sewn with too few stitches. This can reduce the breaking load to approx. 35 kg. This is adequate for flying, but may not be enough for ground handling in strong conditions and large deflection angles. It is possible that the seam may tear during ground handling or at least be damaged. This could pose a danger for the next flight.
Skywalk has therefore issued the following safety notice: MESCAL5 paragliders with the serial numbers listed must have their risers checked or re-sewn before the next flight.
Since you can not tell from the outside whether the seam underneath the cover was correctly sewn, Skywalk recommends sending these paragliders to the importer in the respective country, or directly to skywalk in Germany and Austria. They will be checked and repaired free of charge.
