Airworthiness Directives; McDonnell Douglas Model DC-10 and MD-11 Series Airplanes, and KC-10 (Military) Series Airplanes

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 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.
