Summary
We are revising Airworthiness Directive (AD) 2018-03-03 for certain Textron Aviation Inc. Models 401, 401A, 401B, 402, 402A, 402B, 402C, 411, 411A, 414, 414A, 421, 421A, 421B, 421C, and 425 airplanes. AD 2018-03-03 required repetitively inspecting the left and the right forward lower carry through spar cap for cracks and replacing the carry through spar cap if cracks were found. This AD addresses the same unsafe condition and requires the same actions as AD 2018-03-03, but clarifies the compliance times for the initial inspection of the carry through spar cap. This AD was prompted by several reports of confusion in interpreting the compliance times for the initial inspection of the carry through spar cap. We are issuing this AD to eliminate confusion in interpreting the compliance times for this inspection.
