Abstract
The FAA is adopting a new airworthiness directive (AD) for all Boeing Model B-17E, B-17F, and B-17G airplanes. This AD was prompted by a report indicating that the left front spar lower fitting had completely separated at the wing-to-fuselage joint, and the equivalent joint on the right side of the airplane was cracked. This AD requires inspections of the wing terminal-to-spar chord joints, and repair if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
