The FAA proposes to adopt a new airworthiness directive (AD) for certain Learjet Inc. (Learjet) Model 45 airplanes. This proposed AD was prompted by reports of corrosion found on the upper surface of the lower center wing mid spar splice plate. This proposed AD would require repetitively inspecting the center wing area for corrosion and deterioration of protective treatments, removing any corrosion, and treating any deteriorated areas. The FAA is proposing this AD to address the unsafe condition on these products.
