Components purchased prior to January 1, 1979, are not affected by this AD. B. If any components listed in Table I are found, replace them with approved parts before further flight. C. Future use of any components listed by serial number in Table I is prohibited, unless it is determined by the manufacturer or demonstrated to the FAA that thecomponent is in conformity to type design. D. Upon request of the operator, an FAA Principal Maintenance Inspector may adjust the compliance times if the request contains substantiating data to justify the change, and subject to prior approval by the Manager, Seattle Aircraft Certification Office, for the Boeing Model 747, or the Manager, Los Angeles Aircraft Certification Office, for the McDonnell Douglas Models DC-9 and DC-10. E. Alternate means of compliance with the AD which provide an equivalent level of safety may be used when approved by the Manager, Seattle Aircraft Certification Office for the Boeing Model 747, or the Manager, Los Angeles Aircraft Certification Office for the McDonnell Douglas Models DC-9 and DC-10. F. Aircraft may be ferried to a base for maintenance in accordance with Sections 21.197 and 21.199 of the Federal Aviation Regulations. This amendment becomes effective March 19, 1984.
