## The airworthiness directive

88-25-06 McDONNELL DOUGLAS: Amendment 39-6083. Applies to McDonnell Douglas Model DC-9-81, -82, -83, and -87 series airplanes not equipped with autobrakes, as listed in McDonnell Douglas Alert Service Bulletin A27-298, dated October 5, 1988, certificated in any category. Compliance required as indicated, unless previously accomplished.

To prevent the loss of inboard ground spoilers and the resulting decreased braking performance during landing or rejected takeoff, accomplish the following:

A. Within 30 days after the effective date of this AD, inspect the spoiler control circuit breaker located on the lower electrical power center circuit breaker panel, Row P30 or P33, in accordance with the Accomplishment Instructions of McDonnell Douglas Alert Service Bulletin A27-298, dated October 5, 1988.

1. If a 2-amp circuit breaker is installed, prior to further flight, replace it with a 5-amp circuit breaker in accordance with the above McDonnell Douglas Alert Service Bulletin.

2. If a 5-amp circuit breaker is installed, no further action is required.

B. Within 15 days after the inspection required by paragraph A., above, submit a report of findings, positive or negative, to the Los Angeles Aircraft Certification Office, Attention: ANM-181L, FAA, Northwest Mountain Region.

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 may add any comments 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 inspection requirements of this AD.

All persons affected by this directive who have not already received the appropriate service information from the manufacturer may obtain copies upon request to McDonnell Douglas Corporation, 3855 Lakewood Boulevard, Long Beach, California 90846, Attention: Director of Publications, C1-L00 (54-60). This information may be examined at the FAA, Northwest Mountain Region, 17900 Pacific Highway South, Seattle, Washington or the Los Angeles Aircraft Certification Office, 3229 East Spring Street, Long Beach, California.

This amendment, (39-6083, AD 88-25-06), becomes effective December 16, 1988.
