Summary
This document proposes to supersede Airworthiness Directive (AD) 98-04-27, which currently requires incorporating certain icing information into the FAA-approved airplane flight manual (AFM) of The New Piper Aircraft, Inc. (Piper) PA-23, PA-30, PA-31, PA-34, PA-39, PA- 40, and PA-42 series airplanes. The Federal Aviation Administration (FAA) inadvertently omitted Piper Models PA-31P, PA-31T, PA-31T1, PA- 31T2, and PA-31P-350 airplanes from the Applicability section of AD 98- 04-27. The proposed AD would retain the requirement of incorporating the icing information into the AFM for all airplanes affected by AD 98- 04-27, and would add the Piper Models PA-31P, PA-31T, PA-31T1, PA-31T2, and PA-31P-350 airplanes to the Applicability of that AD. The actions specified by the proposed AD are intended 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.
