Compliance required as indicated, unless previously accomplished. \n\n\tTo prevent inability to discharge the emergency engine fire extinguishing agent when necessary, accomplish the following: \n\n\tA.\tWithin 30 calendar days after the effective date of this Airworthiness Directive, conduct a one time visual inspection of the emergency engine fire shutoff switch cams for proper installation position, and reposition the cams, if necessary, in accordance with McDonnell Douglas Corporation Alert Service Bulletin A76-43, dated April 14, 1986, or later FAA-approved revisions. \n\n\tB.\tSpecial 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 inspection or repositioning requirements of this AD. \n\n\tC.\tAlternate means of compliance which provide an acceptable level of safety may be used when approved by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region. \n\n\tD.\tUpon the request of an operator, an FAA Maintenance Inspector, subject to prior approval by the Manager, Los Angeles Aircraft Certification Office, FAA, Northwest Mountain Region, may adjust the inspection times specified in this AD to permit compliance at an established inspection period of that operator if the request contains substantiating data to justify the change for that operator. \n\n\tAll persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to McDonnell Douglas Corporation, 3855 Lakewood Boulevard, Long Beach, California 90846, attention: Director, Publications and Training, C1-750 (54-60). These documents also may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Los Angeles Aircraft Certification Office, 4344 Donald Douglas Drive, Long Beach, California. \n\n\tThis amendment becomes effective June 9, 1986.
