Requires replacing all hydraulic hoses with hydraulic hoses of an improved design on certain The New Piper Aircraft, Inc.

Full official abstract

This amendment supersedes Airworthiness Directive (AD) 86-17- 07, which currently requires replacing all hydraulic hoses with hydraulic hoses of an improved design on certain The New Piper Aircraft, Inc. (Piper) PA23, PA31, PA31P, PA31T, and PA42 series airplanes. This AD action will require inspecting for improperly manufactured hydraulic hoses replaced during a specific time frame and replacing all affected hydraulic hoses. An incorrect designation of a Piper Model PA31-310 and a Piper Model PA23-150 airplane prompted the proposed AD action. The actions specified by this AD are intended to prevent hydraulic hose failure which could cause loss of hydraulic capabilities resulting in a gear-up landing and possible loss of the airplane.
