## Abstract

This amendment adopts a new airworthiness directive (AD), that is applicable to certain Bombardier Model CL-215-1A10 and CL-215-6B11 series airplanes. This amendment requires repetitive inspections to detect cracking on certain wing to fuselage frame-angles, and repair, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this amendment are intended to detect and correct cracking in the wing to fuselage frame-angles, which could result in reduced structural integrity of the airframe.
