ACTION: Final rule; correction.

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

SUMMARY: This document corrects a typographical error that appeared in 
airworthiness directive (AD) 98-20-35, that was published in the 
Federal Register on September 29, 1998 (63 FR 51803). The typographical 
error resulted in referencing a service bulletin that does not pertain 
to this AD. This AD is applicable to all IAI, Ltd., Model 1121, 1121A, 
1121B, 1123, 1124, and 1124A series airplanes. This AD requires 
repetitive inspections of the trim actuator of the horizontal 
stabilizer to verify jackscrew integrity and to detect excessive wear 
of the tie rod, and replacement of the actuator or tie rod, if 
necessary. This AD also requires accomplishment of the previously 
optional terminating action.

EFFECTIVE DATE: November 3, 1998.

SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 98-20-35, 
amendment 39-10802, applicable to all IAI, Ltd., Model 1121, 1121A, 
1121B, 1123, 1124, and 1124A series airplanes, was published in the 
Federal Register on September 29, 1998 (63 FR 51803). That AD requires 
repetitive inspections of the trim actuator of the horizontal 
stabilizer to verify jackscrew integrity and to detect excessive wear 
of the tie rod, and replacement of the actuator or tie rod, if 
necessary. That AD also requires accomplishment of the previously 
optional terminating action.
    As published, AD 98-20-35 contained an erroneous reference to a 
service bulletin that was approved previously by the Director of the 
Federal Register as of April 10, 1998 (63 FR 11106, March 6, 1998), for 
incorporation by reference in AD 98-05-09, amendment 39-10370. 
Paragraph (f) of AD 98-20-35 and paragraph (g) of AD 98-05-09 
incorrectly reference Westwind Service Bulletin SB 1124-27-046, 
Revision 1, dated May 28, 1997. The correct service bulletin is 
Westwind Service Bulletin SB 1123-27-046, Revision 1, dated May 28, 
1997.
    Since no other part of the regulatory information has been changed, 
the final rule is not being republished.
    The effective date of this AD remains November 3, 1998.
