Abstract
We are adopting a new airworthiness directive (AD) for certain Piper Aircraft, Inc. Models PA-46-310P, PA-46-350P, PA-46R-350T, and PA-46-500TP airplanes. This AD requires inspecting the fuel vent valves to identify if the nitrile parts are installed and modifying and eventually replacing the fuel vent valves if the nitrile parts are installed. This AD was prompted by nitrile fuel vent valves not providing the correct ventilation. If not corrected, this unsafe condition may lead to structural damage of the wings, which could result in loss of control. We are issuing this AD to correct the unsafe condition on these products.
