Abstract
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires removing affected propeller blades from service. This AD was prompted by reports of blades with corrosion pits in the tulip area of the blades. We are issuing this AD to prevent cracks from developing in the tulip area of the blade, which could result in separation of the blade and possible loss of airplane control.
