I guess you are referring to: 2003 Service Bulletin 315-64/2. (As GFA AD 590)
Furthermore: Didn't Grob do static test and restored the original flight speed limitations and maneuver operations for the Twin II and allowed the Twin II Acro only basic aerobatic maneuvers (spins, lazy eights, chandelles, stall turns, steep turns, and positive loops)? Refer to AD 606 http://2009.gfa.org.au/Docs/ADs/GFA%20AD%20606%20Issue%201.pdf The Astir II was loopable, before the AD. I don't loop the Astir I, because it is placarded no aerobatics! I suspect more a/c will have their aerobatic ratings removed as the fleet ages. Sorry for any confusion. _______________________________________________ Aus-soaring mailing list [email protected] To check or change subscription details, visit: http://lists.internode.on.net/mailman/listinfo/aus-soaring
