RIN 2120-AA64


Airworthiness Directives; Israel Aircraft Industries (IAI), Ltd., Model 1121, 1121A, 1121B,


1123, 1124, and 1124A Series Airplanes


AGENCY:
 
Federal Aviation Administration, DOT.


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.


FOR FURTHER INFORMATION CONTACT:
 
Norman B. Martenson, Manager, International


Branch, ANM-116, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton,


Washington 98055-4056; telephone (425) 227-2110; fax (425) 227-1149.


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
2


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.
