CHANGES TO OPERATIONAL LIMITATIONS
Issue 1 of this AD followed investigations of the Grob Twin Astir / Twin Astir Trainer fuselage structure that suggested that the safety margins against damage under limit loads might be inadequate and, to prevent possible damage, reduced operational limits were put in place. Issue 2 revises these limits. Vne is re-instated to 135 Knots IAS although Vb remains limited to 92 Knots IAS. Some aerobatic restrictions also remain. The German LBA has issued AD 2003-231R3 & GROB has issued Alert Service Bulletin 315-64/3, which forms part of this AD.
