Riveted last two aileron spar rivets. Had to use a different bucking bar due to closeness of rivet to stiffener. Riveted last two rivets in end of each end rib with no-hole pneumatic squeezer. Lined up brackets onto #9 right wing rib. Drilled holes in .125 brackets at one end. Discovered that the 2 center holes in both .063 brackets were not properly positioned.
