Airworthiness Directives; McDonnell Douglas Model DC-10 and MD-11
Series Airplanes, and KC-10 (Military) Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
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 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.
