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

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule; correction.

-----------------------------------------------------------------------

SUMMARY: 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.

EFFECTIVE DATE: March 25, 1998.

Directorate, Wichita Aircraft Certification Office, 1801 Airport Road,

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 98-04-37, 
amendment 39-10349, applicable to all Sabreliner Model NA-265-40, -60, 
-70, and -80 series airplanes, was published in the Federal Register on 
February 18, 1998 (63 FR 8086). That AD 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.
    As published, that AD contained an inadvertent omission of the 
complete name of the airplane models in the applicability statement of 
the AD. Throughout the preamble and in the applicability statement of 
that AD, the FAA referred to ``Sabreliner Model 40, 60, 70, and 80 
series airplanes.'' However, the certificate authorizing type design 
authority for these series airplanes identifies the models as 
``Sabreliner Model NA-265-40, -60, -70, and -80 series airplanes.'' 
Although common and standard reference to these models may not include 
the phrase ``NA-265,'' as listed in the type certificate, the FAA has 
determined that omission of part of the official designation of the 
airplane models must be corrected. In all other respects, the original 
document is correct.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
    The effective date of the AD remains March 25, 1998.


Sec. 39.13  [Corrected]

    On page 8089, in the first column, the applicability statement of 
AD 98-04-37 is corrected to read as follows:

equipped with pneumatic deicing boots, certificated in any category.

    Issued in Renton, Washington, on March 19, 1998.
