Airworthiness Directives; Cessna Aircraft Company Models T210N, P210N, and P210R Airplanes

This amendment clarifies information contained in Airworthiness Directive (AD) 98-05-14, which currently requires revising the FAA-approved Airplane Flight Manual (AFM) to specify procedures that would prohibit flight in severe icing conditions (as determined by certain visual cues), limit or prohibit the use of various flight control devices while in severe icing conditions, and provide the flight crew with recognition cues for, and procedures for exiting from, severe icing conditions on certain Cessna Aircraft Company (Cessna) Models T210N, P210N, and P210R airplanes. That publication incorrectly references the possibility of certain ice accumulation on the ``lower'' surface of the wing, instead of the ``upper'' surface of the wing while operating with the flaps extended. This incorrect statement may result in pilot misinterpretation of the icing effects with the flaps extended, and lead to an incorrect action. This document replaces the word ``lower'' with ``upper'' in this sentence. The actions specified in this AD are intended to continue to minimize the potential hazards associated with operating these airplanes in severe icing conditions by providing more clearly defined procedures and limitations associated with such conditions.
