The lever batten tips used in Aeros hang gliders and trike wings Profi TL, Profi and Still are manufactured by Airborne Australia. Airborne has posted a service advisory regarding the lever tips:
The advisory addresses adjustment, maintenance and inspection issues with regard to the lever tips. There have been incidents recently in which lever tips opening in flight have compromised the pilotís control of the glider. Aeros has reviewed the contents of the advisory, and we agree with Airborneís recommendations. We encourage the pilots flying Aeros hang gliders and trike wings equipped with lever tips to read the advisory.
