Abstract
The FAA is superseding Airworthiness Directive (AD) 2017-11-09 for certain Learjet, Inc. (Learjet), Model 60 airplanes. AD 2017-11-09 required a one-time fluorescent dye penetrant inspection of the fuselage skin for corrosion, additional related inspections and corrective actions as necessary, and reporting the inspection results to the FAA. This AD clarifies the compliance time for the inspection and corrects an error in the inspection area of the fuselage skin. This AD was prompted by the identification of an error in the fluorescent dye penetrant inspection of the fuselage skin and an ambiguity in the compliance time for the fluorescent dye penetrant inspection. The FAA is issuing this AD to address the unsafe condition on these products.
