ACTION: Final rule; correction. ––––––––––––––––––––––––––––––––––– SUMMARY: This document corrects erroneous references that appeared in airworthiness directive (AD) 99-06-08 that was published in the Federal Register on March 12, 1999 (64 FR 12249). That AD contained incorrect references to certain paragraphs. This AD is applicable to certain McDonnell Douglas Model DC-10 and MD-11 series airplanes, and KC-10 (military) series airplanes. This AD requires a one-time inspection for blockage of the lubrication holes on the forward trunnion spacer assembly, and a one-time inspection of the forward trunnion bolt on the left and right main landing gear (MLG) to detect discrepancies; and repair, if necessary. EFFECTIVE DATE: Effective April 16, 1999. FOR FURTHER INFORMATION CONTACT: Ron Atmur, Aerospace Engineer, Airframe Branch, ANM-120L, FAA, Transport Airplane Directorate, Los Angeles Aircraft Certification Office, 3960 Paramount Boulevard, Lakewood, California 90712-4137; telephone (562) 627-5224; fax (562) 627-5210. SUPPLEMENTARY INFORMATION: Airworthiness Directive (AD) 99-06-08, amendment 39- 11072, applicable to certain McDonnell Douglas Model DC-10 and MD-11 series airplanes, and KC- 10 (military) series airplanes, was published in the Federal Register on March 12, 1999 (64 FR 12249). That AD requires a one-time inspection for blockage of the lubrication holes on the forward trunnion spacer assembly, and a one-time inspection of the forward trunnion bolt on the left and right main landing gear (MLG) to detect discrepancies; and repair, if necessary. As published, that AD contained four erroneous references to incorrect paragraphs. Paragraph (a) of the final rule states ''For airplanes listed in McDonnell Douglas Service Bulletin MD11-32-074, dated December 15, 1997: Except as provided by paragraphs (c) and (d) of this AD * * *'' However, the exception referenced in that paragraph should have been only to paragraph (c) because, unlike 2 paragraphs (a) and (c) of the final rule, paragraph (d) applies to certain McDonnell Douglas Model DC-10-30, DC-10, -40, and KC-10(A) military series airplanes, not to Model MD-11 series airplanes. Paragraph (b) of the final rule states ''For airplanes listed in McDonnell Douglas Service Bulletin DC10-32-248, dated December 17, 1997: Except as provided by paragraph (e) of this AD * * *'' However, the exception referenced in that paragraph also should have included paragraph (d) because, like paragraph (b) of the final rule, paragraph (d) applies to certain McDonnell Douglas Model DC-10-30, DC-10, -40, and KC-10(A) military series airplanes. The last sentence in paragraphs (d) and (e) of the final rule states ''* * * accomplish the requirements specified in paragraph (a) of this AD.'' Paragraph (d) of the final rule applies to certain McDonnell Douglas Model DC-10-30, DC-10-40, and KC-10A (military) series airplanes, and paragraph (e) applies to certain McDonnell Douglas Model DC-10-10 and DC-10-15 series airplanes. However, those paragraphs require accomplishment of the requirements specified in paragraph (a) of the final rule, which applies to certain McDonnell Douglas Model MD-11 series airplanes. The correct reference should have been to paragraph (b). 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 April 16, 1999. § 39.13 [Corrected] On page 12251, in the third column, paragraph (a) of AD 99-06-08 is corrected to read as follows: * * * * * (a) For airplanes listed in McDonnell Douglas Service Bulletin MD11-32-074, dated December 15, 1997: Except as provided by paragraph (c) of this AD, within 24 months after the effective date of this AD, perform a one-time visual inspection of the lubrication holes on the forward trunnion spacer assembly on the MLG for blockage by opposing bushings, and perform a one-time visual inspection of the forward trunnion bolt on the left and right MLG for chrome flaking, galling, and corrosion in the grooves; in accordance with the service bulletin. * * * * * On page 12252, in the first column, paragraph (b) of AD 99-06-08 is corrected to read as follows: * * * * * (b) For airplanes listed in McDonnell Douglas Service Bulletin DC10-32-248, dated December 17, 1997: Except as provided by paragraphs (d) and (e) of this AD, within 24 months after the effective date of this AD, perform a one-time visual inspection of the lubrication holes on the forward trunnion spacer assembly on the MLG for blockage by opposing bushings, and perform a one-time visual inspection of the forward trunnion bolt on the left and right MLG for chrome flaking, galling, and corrosion in the grooves; in accordance with the service bulletin. * * * * * On page 12252, in the second column, paragraph (d) of AD 99-06-08 is corrected to read as follows: * * * * * (d) For Model DC-10-30, DC-10-40, and KC-10A (military) series airplanes on which the requirements specified in either paragraph (c)(1)(i) or (c)(2)(ii) of AD 96-03-05, amendment 39- 9502, have been accomplished: Within 48 months after the effective date of this AD, accomplish the requirements specified in paragraph (b) of this AD. * * * * *
