## Abstract

We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200PF, and -300 series airplanes. This AD was prompted by reports of cracking found at a certain fuselage frame inner chord. This AD requires repetitive inspections for any cracking of a certain fuselage frame inner chord; identification of the material of a certain fuselage frame inner chord for certain airplanes; and applicable corrective actions. We are issuing this AD to address the unsafe condition on these products.
