Amdt 3

Fuselage Structural Fatigue 12/2000

Applicability: Models 65-90, 65-A90, B90, C90, C90A and E90.

Requirement: Inspect the fuselage structure, and retire the fuselage life-limited components, in accordance with Section 5-11-00, Fuselage and Associated Structure, in the Beech King Air 90 Maintenance Manual P/N 90-590012-13B7 as Revised July 30 1999.

Compliance: Not later than the times shown in the Beech King Air 90 Maintenance Manual.

Note: Compliance with previous issues of this Directive, satisfies the initial inspection requirements of this issue.

This Amendment becomes effective on 30 November 2000.

Background: The original issue of this AD promulgated a fatigue life limitation for the fuselage. It became effective on 31 March 1981.

Amendment 1 became effective on 7 October 1999 and allowed continued operation beyond the previous life limitation, based on an inspection program developed by the manufacturer and published in the maintenance Manual.

Amendment 2 was issued on 2 December 1999 to correct administrative problems which occurred during processing of Amendment 1.

Amendment 3 corrects a minor error and reflects the current amendment status of the Maintenance Manual.
