Full official abstract
We are superseding Airworthiness Directive (AD) 2013-11-03, which applied to certain Viking Air Limited Model CL-215-1A10 and CL- 215-6B11 (CL-215T Variant) airplanes. AD 2013-11-03 required repetitive detailed inspections for cracking of the left-hand (LH) and right-hand (RH) wing lower skin, and repair if necessary. This AD requires repetitive borescope inspections of the LH and RH wing lower skin and repetitive eddy current inspections of the LH and RH wing front and rear lower spar caps. This AD was prompted by reports of a fractured wing lower rear spar cap and reinforcing strap and a report of cracking of the wing lower skin and rear spar. We are issuing this AD to address the unsafe condition on these products.
