Does anyone know if there is a list of AD's posted for the LE XL? My drawings for the XL show the vertical stab leading edge as 1/2" but does not state what material. The trailing edge is 3/4" but does not state what material. The narrative part of the plan set states that all tubing in the tail surfaces are aluminum, yet I remember seeing someplace on the website that Steve Kilblinger ( hope I got the spelling right, Steve ) says that the leading edge of the vertical stab should be changed over to 1/2" 4130 steel. Thanks.
