Airworthiness Directives; The New Piper Aircraft, Inc. (Formerly Piper Aircraft Corporation) Models PA23, PA23-150, PA23-160, PA23-235, and PA23-250 Airplanes

Короткий зміст

This document proposes to supersede Airworthiness Directive (AD) 92-13-04, which currently requires preflight draining procedures on The New Piper Aircraft, Inc. (Piper) Models PA23-150 and PA23-160 airplanes. This proposed action would require installing external fuel ramp assemblies on Piper Models PA23, PA23-150, PA23-160, PA23-235, and PA23-250 airplanes, and incorporating pilots' operating handbook (POH) revisions for Piper Models PA23, PA23-150, and PA23-160 airplanes. Reports of water-in-the-fuel on the affected airplanes, regardless of whether the airplane owners/operators have accomplished preflight draining procedures, prompted the proposed action. The actions specified by the proposed AD are intended to prevent rough engine operation or complete loss of engine power caused by water-in-the-fuel.
