This document makes a correction to Airworthiness Directive (AD) 2004-23-02, which was published in the Federal Register on November 9, 2004 (69 FR 64842), and applies to all Raytheon Aircraft Company (Raytheon) 65, 90, 99, 100, 200, and 1900 series airplanes and Models 70 and 300 airplanes. AD 2004-23-2 requires repetitive inspections of the nose landing gear (NLG) fork for cracks with replacement if cracks are found (replacement terminates repetitive inspections). Current language in paragraph (e)(3) of AD 2004-23-02 references Part III of the Accomplishment Instructions of the service bulletin instead of Part II. This document corrects that paragraph by changing the reference from Part III to Part II.
A correction restates part of an AD that was published incorrectly. It is not an additional requirement and it does not change the AD number or its effective date.

Full official abstract
The FAA supersedes Airworthiness Directive (AD) 87-22-01 R1, which applies to certain Raytheon Aircraft Company (Raytheon) 65, 90, 99, 100, 200, and 1900 series airplanes, and Models 70 and 300 airplanes. AD 87-22-01 R1 currently requires you to repetitively inspect the nose landing gear (NLG) fork for cracks. If cracks are found that exceed certain limits, AD 87-22-01 R1 requires you to replace the NLG fork with a serviceable part or an improved NLG fork (Kit No. 101-8030-1 S or Kit No. 114-8015-1 S, as applicable). Incorporating an improved NLG fork kit terminates the repetitive inspection requirements. This AD is the result of FAA's policy (since 1996) to disallow airplane operation when known cracks exist in primary structure. This AD retains the inspection requirements of AD 87-22-01 R1, requires you to incorporate an improved NLG fork kit anytime a crack is found, and adds additional airplanes to the applicability section of this AD. We are issuing this AD to detect and correct cracks in the NLG fork, which could result in reduced structural integrity and inability of the NLG fork to carry design limit and ultimate loads. The reduced residual strength may cause separation failure of the NLG fork, which could result in loss of control of the airplane during take off, landing, and taxi operations.
