AD Revised on Grob 103 Gliders, 2003-19-14R2, aero

This AD affects the following glider models G 103 Twin Astir, G 103 Twin II, G 103 Twin II Acro, G 103 Twin III Acro.

This AD is a revision based on Grob's completion of analysis of aerobatic flight loads for all models. This AD has now been updated twice. Trying to recap this simply: Twin Astirs go back to original speed and maneuver limits except for a reduction in the rough air speed limit. Twin II (non-acros) go back to original limits. Twin II Acros may be flown as Utility gliders with some simple acro maneuvers approved, but with reduced maneuvering and rough air speed limits. To restore the Twin II Acro to full aerobatic use requires a fuselage stringer kit modification. For Twin III Acros, the prohibition from any aerobatic maneuvers, as well as the reduction of limit airspeeds, remains in place unless the fuselage string kit is installed.

Please note that this AD does not follow exactly the Grob Technical Note.

The effective date of this revision is November 30, 2005.
