In the February issue of King Air magazine, in Dean Benedict’s maintenance article titled “Wing Bolts,” the photo displaying two wing bolts (pictured again below) shows one in tension (top) and one in shear (bottom). The bolt in shear has the brassy stripes. It was held in place by “fingers” that gradually wear off the brassy finish. The remaining brassy stripes indicate the spaces between the wrap-around “fingers.”
Our apologies for any confusion this may have caused.
