REGULATORY TEXT:  
88-01-09 BOEING: Amendment 39-5818. Applies to Model 737-300 series airplanes listed in Boeing Service Bulletin 737-34-1220 dated April 30, 1987, certificated in any category. Compliance required within one year after the effective date of this AD, unless previously accomplished.

A. Replace the EFIS symbol generators in accordance with Boeing Service Bulletin 737-34-1220 dated April 30, 1987, or later FAA-approved revisions.

B. An alternate means of compliance or adjustment of the compliance time, which provide an acceptable level of safety, and which has the concurrence of an FAA Principal Maintenance Inspector, may be used when approved by the Manager, Seattle Aircraft Certification Office, FAA, Northwest Mountain Region.

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

All persons affected by this directive who have not already received the appropriate service documents from the manufacturer may obtain copies upon request to the Boeing Commercial Airplane Company, P.O. Box 3707, Seattle, Washington 98124. These documents may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington, or the Seattle Aircraft Certification Office, 9010 East Marginal Way South, Seattle, Washington.

This amendment becomes effective February 16, 1988.
