Moyes wishes to warn pilots that a Slovenian company intends to produce and distribute uprights which closely resemble their Zoom uprights. These models can be mounted into Moyes gliders, but Moyes urges its pilots against this, as they have been found to be signifcantly lighter and thinner than the true part, with an estimated 30- 50 % less compression strength (buckling resistance) respectively than the original and newer Zoom uprights.
They have similar concerns over the use of retrofit home-made or backyard-produced, untested speedbars and wish to remind pilots that uprights and speed bars are a crucial factor for any hang glider to sustain the +6G load test required to grant a hang glider airworthiness. They warn, “Using retrofit, non-original, non-tested components in your hang glider will in general inevitably put you outside this requirement for airworthiness. In case of an unfortunate accident this might not only harm your health, but likely deprive you of otherwise legitimate insurance claims, if your accident can be related to the presence of such non-tested components”.
