Airworthiness Directives; Sabreliner Model NA-265-40, -60, -70, and -80 Series Airplanes

This document corrects a typographical error that appeared in the applicability statement of airworthiness directive (AD) 98-04-37, amendment 39-10349, that was published in the Federal Register on February 18, 1998 (63 FR 8086). Although the AD referred to the airplane models by using the commonly accepted designations, the typographical error resulted in the omission of the correct and complete type certification name of the specific airplane models addressed by this AD. This AD is applicable to all Sabreliner Model NA- 265-40, -60, -70, and -80 series airplanes and requires revising the 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.
