Brief Description: Riveted the Rear Spar stiffeners to rear spar
Riveted the Rear Spar stiffeners to rear spar. I measured the called out rivets for the stiffeners and it showed that the AN-2704-6 rivets were too short and the AN-27004-7 were a good length. After squeezing a quarter of the rivets, on close inspection I noticed that many of the rivets were toppled or slid. I riveted a hole with the called for AN-2704--6 and got better results. I drilled out the -7 rivets and found that event the apparently OK rivets were also not well done. I finished the rest of the riveting without incident.
