Airworthiness Directives; Piper Aircraft, Inc. Airplanes

We are superseding Airworthiness Directive (AD) 95-26-13 for certain Piper Aircraft, Inc. Models PA-28-140, PA-28-150, PA-28-151, PA-28-161, PA-28-160, PA-28-180, PA-28-181, PA-28-235, PA-28-236, PA- 28R-180, PA-28R-200, PA-28R-201, PA-28S-160, PA-28S-180, PA-32-260, PA- 32-300, PA-32-301, PA-32-301T, PA-32R-300, PA-32R-301 (SP), PA-32R-301 (HP), PA-32R-301T, PA-32RT-300, PA-32RT-300T, and PA-32S-300 airplanes equipped with oil cooler hose assemblies that do not meet certain technical standard order (TSO) requirements. AD 95-26-13 required inspections, replacement, and adjustment of the oil cooler hose assemblies, as well as providing for a terminating action. This AD retains all of the requirements of AD 95-26-13 and adds language to clarify those requirements. This AD was prompted by several inquiries asking for clarification of the AD's applicability and compliance requirements. We are issuing this AD to correct the unsafe condition on these products.
