05/03/2009 … 21-6 Steps 1. With the previously assembly Spar A-1003-L in the cradle I lowered the A-1001A-L Nose Skin and attached with clecos the A-1004-L and A-1004-R Nose Ribs. Then using Blind Rivets LP4-3 I riveted the AS-1004-R Nose Rib to the Spar Assembly then riveted just the A-1004-L and A-1015-R with AN470AD4-5 in six places as shown in Figure 1. Time only about 1 hour for both Ailerons.
