Our Club has a Grob Twin Astir I located in New Jersey with a tail skid and a standard type airworthiness certificate. We're looking for a pneumatic tail wheel conversion for this ship. I contacted Lindner who indicated that they did not support conversions. I know that some ships of this type have pneumatic tail wheels. Does anyone have any information about how our Club might legally convert this ship to a pneumatic tail wheel?

Thanks in advance,

Rob
