AYA stands for American Yankee Association, an international organisation representing about 2000 "Grumman" owners in 17 countries around the world.
As Solent 01 said he had an AA5 which is a Grumman aircraft, Barbox asked if he was a member. I to am thinking of going to my first AYA event in the near future, I think one is being arranged at Sherbun, so Barbox will not have far to go! Hope to see you there.
Our friend in the IMC weight shift is a lot braver than I am.
