Airworthiness Directives; Boeing Model 707 Series Airplanes

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 707 series airplanes. This proposal would require modification of certain areas of the upper skin of the wing. This action is necessary to prevent cracking of the upper skin of the wing, which could result in reduced structural integrity of the wing. This action is intended to address the identified unsafe condition.
