Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to all CASA Model C-212-CB, -CC, -CD, -CE, -CF, and -DF series airplanes. This proposal would require supplemental structural inspections, and repair or replacement, as necessary, to ensure the continued airworthiness of these airplanes. This proposal is prompted by a structural reevaluation, which identified certain significant structural components to inspect for fatigue cracks as these airplanes approach and exceed the manufacturer's original fatigue design life goal. The actions specified by the proposed AD are intended to prevent reduced structural integrity of these airplanes.
