• Mar 9,2007  Be advised that the dimensions for the seat ribs on sheet 5 are not the same as those on the full size drawing on sheet 9. Sheet 9 is the correct size for the ribs.
• Mar 9,2007   Please change the size of the rivet on the canopy latch from 3/32" to 1/8", and do not countersink the rivet. The rivet should be an AN470-4 rivet.
• Mar 22, 2007 the 8" rod going from the brake arm on the rudder pedal to the brake master cylinder should be increased to 8 1/4" Reference sheet 5. The rudder pedal and brake arm can be brazed to the 5/8" tube instead of welding, if you wish.
• Mar 29, 2007 in order for the elevator to reach 22 degrees up travel the stabilizer should be set to 2 3/4" from F12 bulkhead not 2 3/8" as currently shown on sheet 4. This problem is due to the elevator horn not being welded the same on all planes.
• Corrections to Sheet 3: The lower rudder rib should be 27" not 30". The rudder spar flange should face aft. The end view of the rudder spar drawing ( lower end) shows it facing forward, which is a mistake on the drawing.
