REGULATORY TEXT:  
90-16-05 MCDONNELL DOUGLAS: Amendment 39-6614. Docket No. 89-NM-196-AD.

Applicability: Model DC-8 series airplanes, as listed in McDonnell Douglas Report No. MDC K1579, Revision A, dated March 1, 1990, certificated in any category.

Compliance: Required as indicated, unless previously accomplished.

To prevent structural failure, accomplish the following:

A. Within one repetitive inspection interval specified in the service bulletins listed in Table 2.1 of "DC-8 Aging Aircraft Service Action Requirements Document", McDonnell Douglas Report MDC K1579, Revision A, dated March 1, 1990 (hereinafter referred to as "The Document") after the effective date of this AD, or at the inspection threshold specified in McDonnell Douglas Report No. MDC K1579, Revision A, dated March 1, 1990, whichever is later (unless currently being accomplished), begin performing inspections for cracks in accordance with the service bulletins listed in Table 2.1 of The Document. Repeat these inspections at intervals specified in the applicable service bulletins listed in Table 2.1 of The Document.

1. If cracks are found during any inspection, prior to further flight, either accomplish the terminating modification in accordance with the applicable service bulletin, or repair in accordance with data approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: Detection of discrepancies other than cracking necessitates appropriate corrective action in accordance with the provisions of Part 43 of the Federal Aviation Regulations (FAR).

2. Modification in accordance with paragraph B. of this AD terminates individual inspection requirements of the applicable service bulletin.

B. Except as provided below, prior to reaching the incorporation thresholds listed in The Document or within 4 years after the effective date of this AD, whichever occurs later, accomplish the structural modifications in accordance with the service bulletins listed in The Document. Modifications whose time for accomplishment is specified in The Document by a calendar date must be accomplished by that date in lieu of the 4 years specified in this paragraph.

NOTE: The modification required by this paragraph does not terminate the inspection requirements of any other AD unless that AD specifies that any such modification constitutes terminating action for the inspection requirements.

C. An alternate means of compliance or adjustment of the compliance time, which provides an acceptable level of safety, may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region.

NOTE: The request should be forwarded through an FAA Principal Maintenance Inspector (PMI), who will either concur or comment, and then send it to the Manager, Los Angeles Aircraft Certification Office.

D. Special flight permits may be issued in accordance with FAR 21.197 and 21.199 to operate airplanes to a base in order to comply with the requirements of this AD.

The inspections and modifications shall be done in accordance with "DC-8 Aging Aircraft Service Action Requirements Document," McDonnell Douglas Report MDC K1579, Revision A, dated March 1, 1990, which incorporates the following list of effective pages:
